Why buyers pick this one
- Universal 1/2" Reduced Shank
- The precisely machined 1/2-inch (12.7mm) or 13mm round shank fits perfectly into all standard drill chucks, offering secure gripping power and preventing slippage during heavy-torque applications.
- Premium Black Oxide Finish
- The industrial black oxide surface treatment effectively retains cutting fluids, reduces friction, and provides excellent corrosion and rust resistance.
- Industrial Grade HSS Material
- Available in HSS 4241 for economical general-purpose use, or HSS M2 (6542) for prolonged life and increased wear resistance on harder metals.
- Precision Cutting Edge
- Engineered with a 135-degree split point (or 118-degree standard point upon request) to ensure quick penetration and reduce "walking" on the workpiece.
