How to use

Secure the drill bit in the chuck of the drill or drill press, ensuring the bit is centered and tightened. Select an appropriate rotational speed and feed rate for the material being drilled. Use cutting fluid or lubricant when drilling metal to reduce heat and wear. Apply steady pressure and allow the tool to cut without forcing; withdraw periodically to clear chips if required. After use, clean the bit and store it in a dry place to prevent corrosion and damage.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. Match drill speed and lubrication to the workpiece material for best results, and ensure the chuck is compatible with a straight-shank bit of this size.
