How to use

Secure the drill bit in the chuck of a drill driver or drill stand using the cylindrical shank. Select appropriate speed and feed for the material being drilled; lower speeds are recommended for harder metals. Apply steady pressure and allow the drill to cut without forcing. Periodically withdraw the bit to clear chips and prevent overheating.

Recommendations

For best results when drilling metal, use cutting lubricant or coolant, select a suitable drill speed for the material hardness, and maintain a firm grip or stable clamping of the workpiece. Inspect the bit before use and replace it when the tip shows significant wear.
