How to use

Select the bit with the required diameter for the task and secure it in the drill chuck, making sure the shank is fully inserted and tightened. Start drilling at low speed to establish the hole, then increase speed as appropriate for the material. Use steady pressure and maintain the drill perpendicular to the work surface for accurate holes. For plastics and soft metals, reduce speed and clear chips regularly to avoid melting or clogging.

Usage recommendations

Wear appropriate eye protection and follow safe drilling practices. For clean holes in wood, use a backing piece to reduce tear-out. When drilling metal, secure the workpiece and use cutting fluid or lubricant if recommended for the material to extend bit life.
