Description:
Electroplated diamonds have high hardness and wear resistance. Beveled round shank provides easier clamping and more stable working process.
Suitable for polishing jade, amber, stone, beeswax, glass, etc. It is especially used for shaping and polishing spherical beads. Produces clean and accurate spherical beads in minutes with little or no chipping.
Always use lubricant (water or cutting liquid) to cool the workpiece when grinding bit is working. Lower drill pressure and increased use of water lubrication extend the life of the mounting point.
Works with bench drills, hand drills (not included). For general purpose grinding in a wide range of applications, the recommended speed is 2000-3000 rpm/min.
In combination with materials to be processed to select the appropriate feed and cutting speed to improve tool life and improve machining accuracy and performance.
