Bosch PRO Impact P2R2 Screwdriver Bits, 55 mm, 5 Pieces, 2608522527
Bosch 2608522527 is a set of 5 double-ended impact bits from the PRO Impact range, 55 mm long. Each bit carries PH2 on one end and R2 (Robertson square) on the other. The shank is an impact-rated 1/4" hex.
What P2R2 means
The designation describes the two ends: P2 = Phillips 2 - the classic cross recess - and R2 = Robertson 2, a square recess. Robertson is the North American standard and turns up in Europe mainly on imported deck and timber screws, on furniture fittings from American makers and in some fixing systems. A double-ended bit covers both without changing accessories - you just flip it.
Up to 50 times more robust
Bosch states up to 50 times the durability of its standard 2607001528 Extra Hard bit. The difference comes from two things:
Heat-treated modified steel - resistant to high torque instead of twisting permanently.
An extended torsion zone - a narrowed section of the shank that absorbs the impact pulse before it reaches the tip. An impact driver delivers torque in blows; without a torsion zone every blow goes straight into the tip and eventually snaps it.
Magnetic tip
The tip is magnetic, with a black phosphate coating. The magnet holds the screw while you place it one-handed - working at height or in a tight spot, that often decides whether the job is possible at all. The phosphate finish cuts glare and helps the surface hold lubricant.
Colour coding and shank
The bits are colour coded, so you find the size you need without reading it off. The shank is an impact-rated 1/4" hex - it works in an impact driver and in an ordinary drill driver alike.
When bits break - and how to stop it
A bit is a consumable, but most breakages come not from wear but from three specific mistakes. The first is misalignment: if the driver is not square to the screw axis, the angled load concentrates in one corner of the tip. The second is a worn recess - in a screw whose head is already rounded the bit spins in the void, heats up and wears out within minutes. The third is running the impact on too long after the screw has seated - from that point every further blow only fatigues the bit without doing work.
The practical rule is simple: press along the axis and release the trigger the moment the head seats. Follow it and one bit outlasts the pack's rating several times over.

Questions and Answers
How many bits are in the pack?
5 pieces. Each is double-ended, so in practice you have 10 working tips.
What does P2R2 mean?
The two ends of the bit: P2 = Phillips 2 (cross) and R2 = Robertson 2 (square). You flip the bit instead of swapping it.
Where is the Robertson square recess used?
It is the North American standard. In Europe it appears mainly on imported deck and timber screws, on furniture fittings from American makers and in some fixing systems.
What does the torsion zone do?
It is a narrowed section of the shank that absorbs the impact pulse before it reaches the tip. Without one, every blow from the driver goes straight into the tip and eventually breaks it.
How much more durable are they?
Bosch states up to 50 times the durability of its standard 2607001528 Extra Hard bit - the result of heat-treated modified steel and the extended torsion zone.
Do they work in an ordinary drill driver?
Yes. The shank is a 1/4" hex - the bits run in an impact driver and in an ordinary drill driver alike.
Do they hold the screw?
Yes - the tip is magnetic. The screw stays on the bit while you place it one-handed, which at height or in a confined space often decides the job.

Bosch PRO Impact PH2 Screwdriver Bits, 55 mm, 15 Pieces, 2608522523
Bosch 2608522523 is a pack of 15 impact bits in PH2, 55 mm long, from the PRO Impact range. The shank is an impact-rated 1/4" hex.
Why 15 pieces
PH2 is the most-used bit size there is - it covers the bulk of cross-head screws in construction and installation. That is why it is sold in large packs: under heavy use a bit drives a certain number of screws and then gets replaced, and having no spare stops the whole crew. Fifteen pieces means a box that does not run out halfway through the job.
Up to 50 times more robust
Bosch states up to 50 times the durability of its standard 2607001528 Extra Hard bit. It comes from:
Heat-treated modified steel - resistant to high torque instead of twisting permanently.
An extended torsion zone - a narrowed section of the shank that absorbs the impact pulse before it reaches the tip.
An impact driver delivers torque in blows, not smoothly. Without a torsion zone every blow goes straight into the tip; with one, the shank takes the energy by twisting elastically. That is why ordinary bits break in an impact driver within hours while impact-rated ones last months.
The 55 mm length
55 mm is the middle length. Short 25 mm bits are for tight spots, but the driver's nose fouls the workpiece. Long 90 and 150 mm bits reach into deep holes and recessed seats, but they are less stable and wobble as you drive. 55 mm gives enough clearance without losing precision - it is the everyday length.
Magnetic tip and colour coding
The tip is magnetic, with a black phosphate coating - the screw stays on the bit while you place it one-handed. The bits are colour coded, so you find the size in the box without reading labels.

Questions and Answers
How many bits are in the pack?
15 pieces, all PH2 at 55 mm. PH2 is the most-used size, which is why it comes in large packs.
Why 55 mm specifically?
It is the middle length. At 25 mm the driver's nose fouls the workpiece; at 90 and 150 mm the bit wobbles. 55 mm gives clearance without losing precision.
What does the torsion zone do?
It absorbs the impact pulse by twisting the shank elastically before the energy reaches the tip. That is why ordinary bits break within hours in an impact driver while impact-rated ones last months.
Do they work in an ordinary drill driver?
Yes - the shank is a 1/4" hex and the bits run in an impact driver and in an ordinary drill driver alike.
How much more durable are they?
Bosch states up to 50 times against its standard 2607001528 Extra Hard bit - from the heat-treated modified steel and the extended torsion zone.
Do they hold the screw?
Yes - the tip is magnetic with a black phosphate coating. The screw stays on the bit while you place it one-handed.
Does the PH / PZ distinction matter?
Yes. PH (Phillips) and PZ (Pozidriv) look similar but the profile differs. A PH bit in a PZ screw sits at an angle, does not seat fully and chews out the recess - and vice versa. These bits are PH2.

Bosch PRO Impact PZ2 Screwdriver Bit, 150 mm, 1 Piece, 2608522548
Bosch 2608522548 is an impact bit in PZ2, 150 mm long, 1 piece per pack,, from the PRO Impact range. The shank is an impact-rated 1/4" hex.
The PZ2 recess
PZ2 is the most-used Pozidriv size. Pozidriv looks like a cross head but carries four extra smaller ribs between the main arms. They increase contact area and stop the bit camming out the way Phillips does. That is why PZ2 is the standard for timber and furniture screws in Europe.
Up to 50 times more robust
Bosch states up to 50 times the durability of its standard 2607001528 Extra Hard bit. It comes from:
Heat-treated modified steel - resistant to high torque instead of twisting permanently.
An extended torsion zone - a narrowed section of the shank that absorbs the impact pulse before it reaches the tip.
An impact driver delivers torque in blows, not smoothly. Without a torsion zone every blow goes straight into the tip; with one, the shank takes the energy by twisting elastically. That is why ordinary bits break in an impact driver within hours while impact-rated ones last months.
The 150 mm length
150 mm is the longest in the usual range. It replaces a holder plus extension when only one recess is needed: the screw is deep in a bore, between sections or behind an obstruction. The trade-off is stability - at that length any tilt of the machine is multiplied, so it must be held strictly on the screw axis.
Magnetic tip and colour coding
The tip is magnetic, with a black phosphate coating - the screw stays on the bit while you place it one-handed. The bits are colour coded, so you find the size in the box without reading labels.
When a long PZ2 bit is indispensable
Timber and furniture screws in Europe are almost entirely Pozidriv, and it is exactly there that the need for length appears. The classic case is assembling a timber structure: the screw goes through a thick member and its head ends up 8-10 centimetres in from the surface. The second is fixing through a cabinet or box, where the machine cannot get close. In both, the alternative is a holder plus extension - but for a single recess a long bit is more stable: there is no intermediate joint to develop play.

Bosch PRO Impact T20 Screwdriver Bit, 90 mm, 1 Piece, 2608522535
Bosch 2608522535 is an impact bit in T20, 90 mm long, 1 piece per pack,, from the PRO Impact range. The shank is an impact-rated 1/4" hex.
The T20 recess
T20 is a six-lobe Torx recess. Its advantage over a cross head is geometric: force is transmitted perpendicular to the walls of the recess rather than at an angle. So a Torx bit does not cam out, needs no constant end pressure and practically never chews the head. That is what made it the standard on structural screws, furniture fittings and decking.
Up to 50 times more robust
Bosch states up to 50 times the durability of its standard 2607001528 Extra Hard bit. It comes from:
Heat-treated modified steel - resistant to high torque instead of twisting permanently.

The 90 mm length
90 mm is the long bit. It is used where the screw sits recessed, in a deep counterbore or behind an edge - furniture fittings, fixings in a deep hole, or where the driver nose must not touch the visible surface. A long bit is also less stable: it needs the machine held square to the screw axis.
Magnetic tip and colour coding
The tip is magnetic, with a black phosphate coating - the screw stays on the bit while you place it one-handed. The bits are colour coded, so you find the size in the box without reading labels.
Where T20 turns up
T20 is the middle Torx size and appears most often on lighter structural screws, furniture fittings, hinges and electrical boxes. The 90 mm length has a concrete reason there: many of those fixings sit in deep recesses or behind an edge - a hinge in a deep mortice, a screw at the bottom of a box, a fixing through a spacer.

Why two per pack
T30 is among the most heavily loaded Torx sizes - it is used on structural timber screws, where torque is high and the bit works near its limit. Under that duty one bit does not last long, and a two-piece pack is the practical answer: one in the machine, one waiting in the box, instead of the job stopping at the first breakage.

DeWalt EXTREME IMPACT T10 Bits, 57 mm, 5 Pieces, DT7393T-QZ
DeWalt DT7393T-QZ is a pack of 5 impact bits in T10, 57 mm long. The bits have an extended torsion zone and are made for impact drivers.
The T10 recess
T10 is a small Torx size. The six-lobe profile transmits force perpendicular to the walls of the recess rather than at an angle - so a Torx bit does not cam out and needs no constant end pressure on the machine.
At small sizes like T10 that matters even more: a thin cross recess would chew out at the first serious load, while Torx takes it. That is why T10 turns up on furniture fittings, electrical boxes, appliances and housings.
The torsion zone
An impact driver delivers torque in pulses, hundreds of times a minute. Without a torsion zone every pulse goes straight into the tip and eventually snaps it. An extended torsion zone is a narrowed section of the shank that twists elastically and absorbs the blow before it reaches the tip.
The 57 mm length
57 mm is the middle length. It gives more clearance than a short 25 mm bit - the driver nose does not foul the workpiece - and stays more stable than the long 90 and 157 mm bits, where any tilt of the machine is multiplied.
Why five pieces
A bit is a consumable, and small Torx sizes like T10 are also the most fragile: the tip is thin and unforgiving of a tilted machine. Five pieces means a broken bit does not stop the job.
T10 versus TX10
T10, TX10 and Torx 10 are the same profile - only the maker's notation differs. Watch out for TR10 though: that is the security version with a pin in the centre, which will not accept a normal T10 bit and turns up on covers and housings the maker would rather you did not open.

Questions and Answers
How many bits are in the pack?
5 pieces, all T10 at 57 mm.
What is the difference between Torx and a cross head?
Torx transmits force perpendicular to the walls of the recess rather than at an angle. The bit does not cam out, needs no constant pressure and practically never chews the head.
Can I use a hex key instead of Torx?
No. A hex bears on only three points in a Torx recess and rounds it out at the first serious load.
What does the torsion zone do?
It twists elastically and absorbs the impact pulse before it reaches the tip. Without it every blow goes straight into the tip and snaps it.
Why 57 mm?
57 mm gives more clearance - the driver nose does not foul the workpiece - and stays more stable than the long 90 and 157 mm bits.
Do they work in an ordinary drill?
Yes. The fitting is a standard 1/4" hex and the bits run in either type of machine.
Why do small Torx bits break more often?
Because their tips are thin and unforgiving of a tilted machine. At T10 any angled load concentrates in a very small area - which is why they are sold in multi-packs.

DeWalt EXTREME IMPACT PZ2 Bits, 50 mm, 5 Pieces, DT7391T-QZ
DeWalt DT7391T-QZ is a pack of 5 impact bits in PZ2, 50 mm long. The bits have an extended torsion zone and are made for impact drivers.
The PZ2 recess
PZ2 is the most-used Pozidriv size in Europe. Pozidriv looks like a cross head but carries four extra smaller ribs between the main arms. They increase contact area and stop the bit camming out of the screw - the difference from Phillips, where constant end pressure on the machine is mandatory.
That is why PZ2 is the standard on timber screws, plasterboard, furniture fittings and very nearly everything in installation work in Europe.

50 mm is the middle length. It gives more clearance than a short 25 mm bit - the driver nose does not foul the workpiece - and stays more stable than the long 90 and 150 mm bits, where any tilt of the machine is multiplied.
Why five pieces
A bit is a consumable. Under heavy use PZ2 wears out fastest because it is used most - and that is exactly when having no spare stops the work. Five pieces means a box that does not run out halfway through the job.
Impact driver or drill driver
These bits are designed for an impact driver but work in a drill driver too. The reverse does not hold: an ordinary bit in an impact driver snaps at the shoulder within the first few screws, because it has no torsion zone to absorb the blows. If both kinds are mixed in a case, the impact ones are the ones with the thinner waist.

Questions and Answers
How many bits are in the pack?
5 pieces, all PZ2 at 50 mm.
What is the difference between PZ and PH?
Pozidriv (PZ) has four extra ribs between the arms of the cross. They stop the bit camming out - with Phillips (PH) that is compensated by constant end pressure on the machine.
Can a PH bit go in a PZ screw?
It can, but it should not. A PH bit sits at an angle, does not seat fully and chews out the recess - after which nothing will remove the screw.
What does the torsion zone do?
It twists elastically and absorbs the impact pulse before it reaches the tip. Without it every blow goes straight into the tip and snaps it.
Why 50 mm rather than 25?
50 mm gives more clearance - the driver nose does not foul the workpiece - and stays more stable than the long 90 and 150 mm bits.
Do they work in an ordinary drill?
Yes. The fitting is a standard 1/4" hex and the bits run in either type of machine.
Why does PZ2 run out first?
Because it is used most - it is the standard on timber screws, plasterboard and furniture fittings. That is why it is sold in multi-packs.

Bosch PRO Impact Double-Ended Bit, T30, 65 mm, Pick and Click
Bosch 2 608 522 542 is one double-ended impact bit from the PRO Impact range, size T30 at both ends, 65 mm long, on the Pick and Click system. The T30 marking is laser-etched at both ends of the bit itself.
Double-ended - why it matters
The bit has working tips at both ends. When one wears out, turn the bit round and carry on with the other. In practice that doubles the life of a bit. With an impact driver, wear comes fast - the tip takes thousands of blows a minute - so the difference shows within a single job.
Steel made for impact
PRO Impact bits are made from modified steel intended for impact drivers. An ordinary bit is hard and brittle: under impact it simply shatters at the tip. An impact bit is tougher and has a narrowed section in the middle that absorbs the twist like a torsion spring instead of passing it to the tip.
Pick and Click
Pick and Click is Bosch's system of boxes with sized holes: every bit sits in its own slot with the size printed beside it. The point is not having to hunt for the right size in a pocket - on site that is the time most often lost while driving screws.
The laser marking
The size is laser-etched, not printed. Print rubs off within a week in a tool bag; laser marking stays readable for the life of the bit. In a box of fifteen bits of different sizes that matters more than it sounds.
T30 - which screws
T30 is a Torx size found on structural timber screws, ironmongery, furniture connectors and decking screws. A Torx head does not cam out the way a Phillips does, which with an impact driver is essential - a bit that slips destroys the head in a fraction of a second.
Compatibility
The shank is 1/4 inch hex - the standard on drivers, impact drivers and bit holders.

Questions and Answers
How many bits are in the pack?

Impact bits
Impact bits for screwdrivers, impact wrenches, and heavy-duty applications
Impact bits are used with screwdrivers and impact drivers where torque is higher and the load on the tip is significantly greater than during standard fastening. They are designed for installation, repair, assembly of structures, working with fasteners in wood, metal, drywall, profiles, furniture, machinery, and service work. A properly selected bit reduces slippage in the screw head, protects the fastener, and helps ensure more precise power transfer from the tool to the screw.
In impact mode, a standard bit often wears out quickly, bends, or breaks under peak load. Impact bits are designed to absorb the sudden impulses from the machine. In many models, this is achieved through a torsion zone that absorbs part of the stress and protects the tip from premature damage. Such bits are a practical choice for professional installers, technicians, construction crews, carpenters, auto mechanics, and demanding DIYers.
What do impact bits include?
The range includes bits for various types of fasteners and tasks. Options range from individual bits to small sets for everyday installation and more comprehensive sets for workshops or service centers. When selecting, consider the profile shape, size, length, material, fit with the holder, and compatibility with the power tool being used.
- PH and PZ bits-for Phillips-head screws used in furniture assembly, woodworking, paneling, and light-duty construction.
- Torx bits-for six-point star screws used in machinery, automobiles, metal assemblies, and wooden structures.
- HEX bits-for internal hex heads on fasteners, furniture screws, mechanical assemblies, and service operations.
- Flat bits - for standard slotted screws in repair and assembly work.
- Long impact bits - for deeper access, working in profiles, corners, housings, and hard-to-reach places.
- Short bits - for compact work with a holder, extension, or directly in a chuck with a 1/4'' hex drive.
Differences between the various types
Impact bits differ not only in the shape of their tips. The profile must match the screw exactly, because even a slight mismatch accelerates wear and increases the risk of damaging the head. For example, PH and PZ look similar but are designed for different cross-head fasteners. The Torx profile transmits torque more reliably when the size is correct, while HEX is required for screws with an internal hexagon.
Length also affects performance. Short bits are more stable for direct tightening and take up little space in a toolbox or pocket organizer. Bits measuring 50 mm, 75 mm, or longer facilitate access when working in recesses, channels, and assembled components. In tight spaces, a long bit often eliminates the need for an additional extension.
The material and heat treatment are important for long-term use. Tool steel is often used, including S2 steel for heavier-duty series. Coatings such as black oxide, phosphate coating, or a titanium finish can help protect against corrosion and reduce wear on the working part. Magnetized tips facilitate screw positioning, especially when working with one hand or overhead.
Selection Based on the Tool and Task
When working with an impact driver, it is advisable to choose a bit designed for impact loads. Such bits are designed for high torque and are better suited for driving long screws, self-tapping fasteners, screws for wood construction, and metal profiles. Impact bits can also be used with a standard cordless screwdriver, provided the shank and size match.
The most common bit shank is 1/4" hex, compatible with most holders, magnetic adapters, extensions, and bit sockets. For impact wrenches with a square drive, an adapter is often required. When using a holder, it is best for the bit to fit securely without excessive play, as this improves control and reduces wear on the tip.
For serial tightening of the same fasteners, it is better to select several identical bits in the exact size rather than working with an unsuitable profile. For mixed tasks, sets of impact bits with different profiles and lengths are a practical option. This way, the toolbox contains ready-to-use bits for furniture assembly, building wooden frames, fastening metal strips, repairing appliances, or workshop maintenance.
Practical criteria when buying
Good compatibility between the screw, bit, and tool is crucial for clean work. A bit that is too small will slip in the screw head, while one that is too large will not fit into the profile. For Torx fasteners, sizes T10, T15, T20, T25, T30, and T40 cover various applications, while PH2 and PZ2 Phillips screws are very common in assembly work. Smaller sizes are also used for furniture and appliances.
- Check the screw head type-PH, PZ, TX, HEX, or flat slot.
- Match the size-the tip must fit snugly into the fastener head.
- Choose the length-a short bit for stability, a long bit for access.
- Check for impact drive marking-required for impact drivers and heavy-duty tightening.
- Consider the drive-1/4" hex or use an adapter.
- Plan for spares-in continuous use, bits are consumables and wear out over time.
Operation, Safety, and Maintenance
Even a sturdy impact bit needs to be used correctly. The tool must be guided along the screw's axis, without tilting sideways. The pressure should be sufficient to prevent the tip from slipping, but not excessive. With hard materials and long fasteners, pre-drilling often protects the screw, the bit, and the workpiece. A worn bit with rounded edges should be replaced, as it begins to damage the fasteners and makes removal difficult.
After use, it is best to clean the bits of shavings, dust, and coating residue. Storing them in a holder, case, or box protects the tips from impact and prevents mixing up sizes. When working outdoors or in a damp environment, dry storage reduces the risk of corrosion. This keeps the bits organized and ready for the next task.
Impact bits for precise and secure installation
The impact bits selected at Toolsbox.bg assist with daily installation, construction, service, and repair tasks. Choose the right profile, size, and length based on the fastener and the tool you're using. This will give you better control when tightening, fewer damaged screws, and a more organized workspace in the workshop, on the job site, or at home.
