#3 x 6" Square Power Bit - 1/4" Quick-Change Hex - 10 Pack

Benchmark Abrasives #3 x 6" Square Power Bits are professional-grade driver bits built for long-reach fastening applications where standard-length bits cannot easily access the screw. 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 construction, maintenance, assembly, woodworking, fabrication, and repair work.

The #3 square tip is CNC precision-ground to exact dimensions for a tight, secure 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 extended 6" overall length provides substantial reach into recessed, obstructed, and hard-to-access areas, while the 1/4" hex ball-groove quick-change shank provides secure retention, fast 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 extended 6" length is especially useful for deep recesses, confined spaces, recessed hardware, and applications where additional clearance is needed between the driving tool and the workpiece. For best performance, match the #3 square tip to the correct fastener recess, keep the bit aligned squarely with the screw, and use controlled speed and torque appropriate for the application.

Safety Tips

• Always wear appropriate eye protection and other PPE required for the application.
• Match the #3 square tip to the correct fastener size before applying torque.
• Keep the long bit aligned squarely with the fastener to reduce slipping, tip damage, and side loading.
• Make sure the quick-change shank is fully seated and securely retained before operating the tool.
• Use controlled speed and torque appropriate for the fastener and work material.
• Avoid excessive lateral pressure on the extended 6" bit during operation.
• Inspect bits before use and replace any that are bent, cracked, excessively worn, rounded, or otherwise damaged.
• Follow all operating and safety instructions supplied with the power tool.
