The Bosch SG250 TEK Screwgun features a compact, design for lighter weight and better tool balance. Its ergonomic contoured grip provides maximum comfort and minimal fatigue by evenly distributing gripping pressure. The Posi-Lok™ nose piece retains the depth setting when removed from the tool, eliminating time-consuming depth readjustment. The SG250 also features a high-torque gearbox that allows for the continuous driving of screws into hardwoods and engineered materials, as well as drywall and soft woods. It includes both TEK and drywall nose pieces.
