How to use

Mark the screw position and secure the workpiece. Use a drill or drill press with appropriate speed for the material, clamp the countersink bit in the chuck and carefully drill to the required depth so the screw head sits flush with the surface. For metal, use cutting fluid where appropriate and apply steady, moderate pressure to avoid overheating.

Recommendations

Choose the correct countersink size to match the screw head and test on scrap material before final drilling. Keep the bits clean and store them in the blister pack to prevent damage. For prolonged life when working with metal, control speed and use coolant as needed.
