How to use

Secure the countersink drill bit in the drill chuck and tighten firmly. Mark the screw centre on the workpiece and position the tip of the countersink at that mark. Drill at a steady, controlled speed, applying moderate downward pressure until the desired recess depth is achieved. Periodically check the screw seating and adjust depth as required. After use, remove any chips and store the bit in a dry place to preserve cutting edges.

Usage recommendations

For best results, start at a low speed when countersinking metals and increase speed slightly for wood and plastics. Use appropriate personal protective equipment and clamp the workpiece to prevent movement. If cutting performance decreases, dress the hole and remove burrs before final assembly.
