Use in a stable drill press, CNC machine, milling machine, PCB drill holder, or other controlled setup. Not recommended for handheld electric drills or unstable setups. Secure the workpiece and keep the drill properly aligned. Use proper feed pressure, spindle speed, and chip clearing for the material being drilled.
