Bosch GBM hand drills are corded rotary drills for clean holes in wood, metal and plastic. With no hammer action, they give precise control for fabrication, carpentry, furniture and installation work, and the larger models also handle mixing and big-diameter bits.
How to choose a Bosch hand drill
- Chuck size: 6.5mm (1/4") drills are light and quick for small holes. 10mm (3/8") is the all-round size. 13mm (1/2") models take larger bits and hole saws.
- Power: 320W to 450W suits light and everyday drilling. 600W to 850W handles large bits, hole saws and mixing paint or mortar.
- Reverse and variable speed: "RE" models have variable speed and reverse, so you can start holes slowly and back out stuck bits.

Hand drill or impact drill?
A hand drill gives the cleanest holes in metal and wood. For brick and masonry, choose a Bosch impact drill with hammer action. For screws, a drill driver with a clutch is easier to control.
Pair your drill with metal drill bits, wood drill bits or a drill bit set.
All Bosch tools from KHM Megatools are genuine units covered by the official Bosch warranty in the Philippines.
