Bosch UNEO 12 LI 12v Cordless Rotary Hammer Drill

The Bosch UNEO 12 LI is a compact 12V cordless rotary hammer drill offering three functions in one tool: hammer drilling, drilling, and screwdriving.

Powered by a pneumatic Bosch hammer mechanism, it delivers an impact rate of up to 4,800 bpm with a single impact force of 0.5 J, making it capable of hammer drilling in concrete up to 10 mm diameter. The two-speed gearbox (0–280 rpm in first gear, up to 900 rpm in second) lets the user switch between higher torque for demanding materials and higher speed for faster work through wood or metal.

The SDS-System chuck accepts both SDS quick bits and 1/4" hex accessories, with bit changes taking as little as three seconds — practical on site where time matters. At just over 1.1 kg net weight, the tool is well suited to overhead work, tight spaces, and jobs where a full-size SDS drill would be excessive.

As part of the Bosch 12V POWER FOR ALL system, the battery is compatible with tools across 10+ brands and 150+ products, making it a sound investment for tradespeople already working within this platform.
