Bosch GDR impact drivers drive screws and bolts with rapid rotational blows, so long screws go in quickly without the tool twisting your wrist. They are the go-to tool for roofing, steel framing, decking and any job with a lot of repetitive fastening.
How to choose a Bosch impact driver
- Torque (Nm): around 100Nm to 110Nm handles most screws in wood and light steel. 160Nm and above drives lag bolts, tek screws and long coach screws.
- 12V or 18V: 12V models are compact for tight work and all-day overhead use. 18V models give more power and speed for heavy fastening.
- Brushless motor: brushless GDR models run longer per charge and need less maintenance.
- 1/4" hex chuck: impact drivers use 1/4" hex bits, so make sure your bits are impact-rated.

Impact driver or impact wrench?
An impact driver is built for screws. For nuts and bolts on vehicles, machinery and steel structures, a Bosch impact wrench with a square drive gives far higher torque. For precise work where you need a clutch, use a drill driver.
Pair your impact driver with impact-rated screwdriver bits and spare 18V batteries.
All Bosch tools from KHM Megatools are genuine units covered by the official Bosch warranty in the Philippines.
