    Diamond Drill Bits

    Important: When using diamond coated drills, points, wheels etc:

    Always completely submerge, both drill bit cutting surface and object being drilled, in water.
    Use light pressure
    Between 5,000-20,000 rpm
    Lift often
    Best results when used in a drill press
    Use bur lubricant or beeswax on cutting surface
    If diamonds are being worn off too quickly or bit becomes hot and discolors, you are not using the above guidelines.
    Because of the nature of the diamond coating process, drill bit diameters may vary by as much as ±0.5 mm
