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
plus or minus 0.5 mm
