Solid Drill Bit Carbide 5/16"
(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
• Recommended for drill press operation only
NOTE: Cobra™ Drill Bits should be run at higher speeds than standard high-speed steel twist drills. It is also recommended that a woodpeckering technique be used to prevent chips from clogging in the flutes.
CAUTION: Any cutting tool may break or shatter under improper use. Government regulations require use of safety glasses and other appropriate safety equipment at all times in the vicinity of use.
