Product Specification
T15 x 1" STAR / TORX® INSERT BIT - 1/4" HEX - 10 PACK
Benchmark Abrasives T15 x 1" Star / TORX® Insert Bits are professional-grade driver bits built for contractors, technicians, fabricators, and maintenance professionals who need accurate fastener engagement and dependable torque transfer. 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 applications.
The T15 star tip is CNC precision-ground to exact dimensions for a secure, consistent fit with compatible T15 star and TORX® screws. Precise tip geometry helps improve contact with the fastener recess, transfer torque efficiently, and reduce unnecessary slipping or premature wear. A standard 1/4" hex shank makes these compact 1" insert bits easy to use with compatible bit holders, screwdrivers, drills, and other properly equipped driving tools.
