06415 15-Piece S2 Steel Screwdriver Bit Set | ½” Dr. Star

06415 Series is built for mission-critical mechanical service:

• Premium S2 Alloy Steel: The defining technical feature. Every bit is forged from S2 steel, which offers higher shock resistance and hardness (HRC 58-62) than standard Chrome Vanadium. This ensures the Star points do not “cam-out” or shear under high torsional loads.
• 10mm Hex Shank Architecture: Unlike consumer-grade bits, these utilize a 10mm hex base. This larger surface area provides a more secure interface with the holder, allowing for the transfer of high torque from 1/2″ drive tools without the risk of the bit spinning in the socket.
• Dual-Length Strategic Loadout: * 30mm Length: Optimized for maximum rigidity and high-clearance tasks where tool-stack height must be minimized.
  • 75mm Length: Calibrated for “Deep-Reach” applications such as cylinder head bolts or recessed sensor housings.
• 1/2″ Drive Bit Holder Socket: Includes a precision-machined 1/2″ square drive to 10mm hex adapter. This allows the bits to be used directly with professional-grade ratchets, breaker bars, and torque wrenches.
• Precision Star (T-Series) Spectrum: Covers the most critical industrial sizes: T20, T25, T30, T40, T45, T50, and T55.
