RYOBI R18CK4F-252S 18V ONE+ 4-Piece Cordless Combo Kit with 2 Batteries and Charger - 5133004771

RYOBI R18CK4F-252S 18V ONE+ 4-Piece Cordless Combo Kit (article 5133004771)

RYOBI R18CK4F-252S is a set of four cordless machines on the ONE+ 18V platform, supplied with two batteries, a charger, a 55-piece bit set and a fabric carry bag. The kit contains a percussion drill-driver R18PD31-0, a jigsaw R18JS-0, an angle grinder R18AG-0 and a palm/delta sander R18PS - drilling and driving, straight and curved cutting in wood, cutting and grinding metal, and fine surface finishing, all covered by a single battery standard. The manufacturer publishes the kit under article number 5133004771 and EAN 4892210186584.

The point of a kit like this is the battery, not only the discount: all four machines run on the same packs, charge from one charger and travel in one bag. The two batteries differ in capacity - 5.0 Ah and 2.0 Ah.

R18PD31-0 percussion drill-driver

The drilling and driving machine in the kit delivers 50 Nm of maximum torque and has a percussion function, so besides wood and metal it also drills masonry. It has two gears that set the maximum speed to suit the material - low gear for high torque when driving screws, high gear for drilling. The chuck is a 13 mm keyless type with a lock, and the spindle has an automatic lock, so changing a drill bit or a screwdriver bit is a one-handed job.

R18JS-0 jigsaw

The jigsaw cuts wood up to 101 mm, aluminium up to 10 mm and steel up to 6 mm. Stroke length is 25 mm and the stroke rate is variable between 1100 and 3000 min^-1, which lets the same saw handle both cladding boards and thin sheet metal. The four-stage orbital action is selected to match the material: off for a clean edge and scroll cuts, on for fast straight cutting in thick stock. Blades change without tools and the machine accepts both T-shank and U-shank blades. Weight without battery: 2.1 kg.

R18AG-0 angle grinder

The angle grinder takes a Ø115 mm disc with a Ø22 mm bore and an M14 spindle thread - the most common size, for which discs are available everywhere. No-load speed is 7500 min^-1. The guard rotates and locks without tools, and the side handle mounts in three positions, so the machine sits comfortably for cutting and for rough grinding, left-handed or right-handed. A spindle lock makes disc changes quick. Weight without battery: 2.5 kg.

R18PS palm/delta sander

The delta (triangular orbital) sander is intended for light to medium paint removal and finishing work. The orbital movement is 1.8 mm, and the compact body with its triangular pad reaches into corners, skirting and narrow spaces where a random orbit sander will not fit. Abrasive sheets attach with hook-and-loop and change in seconds. The machine has a dust extraction adapter that connects to an ordinary vacuum cleaner, and a lock-on switch for continuous running.

Batteries, charger and the ONE+ platform

All four machines are part of the RYOBI ONE+ 18V system. That means the battery is shared across the whole range - the same packs power the other ONE+ tools, the brand's garden machines and its lighting, with no adapters. The kit includes RB18L50 (18V, 5.0 Ah Lithium+) and RB18L20 (18V, 2.0 Ah Lithium+), together with an RC18120 fast charger. The manufacturer states a charging time of 75 minutes.

Why the machines carry a "-0" suffix although the kit does include batteries

This is the most common misunderstanding with RYOBI, so we state it plainly. The "-0" suffix on an individual machine (as do the words SOLO and body) means that machine is sold without a battery and without a charger. Inside this kit the machines genuinely are bare tools - R18PD31-0, R18JS-0 and R18AG-0 have no batteries of their own. The kit as a whole, however, is NOT a SOLO item: it contains two batteries and a charger, listed separately in the contents below. In other words, R18CK4F-252S is ready to work straight away, with no power source to buy on top.

Applications

The set covers typical household and workshop work: assembling furniture and running electrical fittings with the drill, holes in brick and concrete using the hammer mode, cutting boards, cladding and chipboard with the jigsaw, shaped cut-outs for a sink or a socket, cutting profiles, rebar and sheet metal and removing rust and weld beads with the angle grinder, and preparing window frames, skirting and furniture for painting with the delta sander. The kit suits home improvers, property maintenance and fitters who need a light set of machines sharing one battery system.

Technical specifications per machine

A dash means the value does not apply to that machine or is not published by the manufacturer. Figures for R18PD31-0 and R18PS come from RYOBI's description of the kit, those for R18JS-0 and R18AG-0 from the official pages of the individual machines.
