Installation Notes

This bit is installed by machinists and trade technicians using standard 3-jaw or keyless drill chucks. Ensure the workpiece is securely clamped before drilling and that the drill chuck is fully tightened to prevent bit slippage. Use appropriate cutting fluid when drilling steel or superalloys to extend bit life. Inspect the cutting edges for wear before use and replace the bit if chipping or dulling is present.
