(Pack of
1.0)
Modified relief angles on a 135° point penetrate the workpiece easier while maintaining a durable outside cutting edge
Titanium CarboNitride (TiCN) coating improves heat resistance and reduces wear to the cutting edges; outperforms Titanium Nitride (TiN) coatings
Three-flute design removes chips effectively
No cutting fluids are needed for Cobra™ Drill Bits
Three flats are ground on the shanks (size 1/4" and greater) to reduce the chances of slippage and breaking
For use on heat-treated, hardened material up to Rc 65
