Troubleshooting
Countersink hole is too large or too small.
Ensure you are using the correct countersink size for your screw. The drill bit size may also need adjustment; use the hex key to set the drill bit depth for your desired pilot hole size.
Drill bit is not cutting effectively.
Check if the drill bit is dull. For best results, ensure the bit is sharp. Also, verify that you are using the appropriate speed setting on your drill for the material.
Bit is slipping in the drill chuck.
Ensure the 1/4" hex shank is fully inserted and the chuck is tightened securely. Use a drill with a keyless chuck for optimal grip.
Countersink is not sitting flush with the surface.
Adjust the depth of the countersink by slightly reducing the drilling pressure or ensuring the drill is not set to an excessively high speed. The drill bit's depth can also be adjusted for shallower or deeper pilot holes.
