Bosch GSB 18V-25 Professional Cordless Impact Drill/Driver, 56 Nm, Bare Tool - 06019K9300

Bosch GSB 18V-25 Professional Cordless Impact Drill/Driver, Bare Tool

The Bosch GSB 18V-25 Professional is a compact cordless impact drill/driver on the Bosch Professional 18 V system. It delivers 56 Nm in hard driving (up to 60 Nm maximum torque) and weighs 1.2 kg without a battery - a combination that lets the machine be carried all day without noticing it, while still handling work that usually calls for a bigger drill.

Two gears - and why the slow one matters

The gearbox is two-speed: 0-440 and 0-1,650 rpm. The high speed is for drilling, the low one for driving. The difference is not comfort but torque: in first gear the machine has the force to drive a long screw into hard timber without stalling, and does it slowly enough to stay controllable. Speed is variable from the trigger.

Hammer action for masonry

Unlike a plain driver, the GSB has a hammer mode - the chuck adds axial blows to the rotation and the machine drills brick, aerated concrete and block. For an anchor in a wall that is the difference between a usable and a useless tool. It switches with a collar on the body.

Chuck and torque

The chuck is keyless, 1.5-13 mm - the full range, so the machine takes both a thin metal bit and a 13 mm wood bit without an adaptor. The torque limiter works through a stepped collar, so driving stops at the set force instead of shearing the screw head or punching through plasterboard.

Vibration - the figures that decide how long you work

Drilling in metal measures 1 m/s² - effectively unnoticeable. Impact drilling in masonry rises to 12.8 m/s², which is normal for hammer action but means continuous hammer drilling should be broken up with pauses. For driving and plain drilling this is a calm machine.

What "bare tool" means

Article 0 601 9K9 300 is supplied in a cardboard box, without battery and without charger. It is intended for people already on Bosch Professional 18 V batteries, which are common to the whole blue 18 V range.
