#3 X 2" Square Power Bit - 1/4" Quick-Change Hex - 10 Pack

Benchmark Abrasives #3 x 2" Square Power Bits are professional-grade driver bits built for secure fastener engagement, dependable torque transfer, and added reach in construction, maintenance, assembly, woodworking, fabrication, and general shop applications. Each bit is manufactured from heat-treated S2 shock-resistant tool steel hardened to HRc 60 for the strength, toughness, and wear resistance required in repeated screwdriving work.

The #3 square tip is CNC precision-ground to exact dimensions for a tight, consistent fit with compatible #3 square-recess fasteners. Precise tip geometry helps maximize contact inside the fastener recess, transfer torque efficiently, and reduce unnecessary slipping or premature wear. The 2" overall length provides additional reach over standard 1" insert bits, while the 1/4" hex ball-groove quick-change shank provides secure retention, faster bit changes, and easy removal from compatible chucks and quick-change systems.

Applications & Performance

Designed for driving and removing compatible #3 square-recess screws and fasteners in construction, maintenance, assembly, woodworking, fabrication, repair, equipment service, and other professional or DIY fastening applications.

The 2" length provides added reach around fixtures, hardware, recessed fasteners, and other areas where a shorter insert bit may be less convenient. For best performance, match the #3 square tip to the correct fastener recess and keep the bit square to the screw during operation.
