How to use

Install the drill bit in a compatible handheld or stationary drill with an appropriate chuck size, ensuring the shank is fully seated and tightened. Select drill speed and feed appropriate for the material: lower speeds for metals, medium to higher speeds for wood and plastics. Apply steady pressure without forcing the bit; withdraw periodically to clear chips when drilling deeper holes. After use, remove debris from the flute and store the bit in a dry place.

Recommendations

Use appropriate personal protective equipment (safety glasses, gloves) and clamp workpieces securely. Match drill speed and lubrication to the material — use cutting oil for ferrous metals to extend bit life. Replace the bit if it becomes dull or damaged to maintain drilling quality.
