How to use

Install the 4mm cylindrical shank into a compatible drill chuck and tighten securely. Adjust the countersink to the desired diameter and set the depth stop for the required drilling depth. Drill at a steady speed appropriate for the workpiece material—lower speeds for hardwood and higher speeds for plastic and softwood—applying moderate pressure until the depth stop contacts the surface.

Recommendations

For best results, use appropriate drill speeds for each material, clamp thin or flexible workpieces, and clear chips regularly. Inspect bits for wear and replace when cutting edges become dull to maintain clean holes and prevent material damage.
