Description

This 4.0 mm round diamond point carves stone and cleans up work in glass, ceramics, and metals at the bench. Diamond Supreme builds it by electroplating diamond particles onto a stainless steel form, creating a precise, durable cutting instrument made to last many times longer than cheaper alternatives.

At 1-3/4" (44.5 mm) in total length, this diamond point matches the standard length of popular tungsten vanadium burs from Pfingst, Fox Germany, and Otto Frei Swiss, so it drops straight into an existing setup. The 3/32" stainless steel shank fits standard handpiece collets used throughout the trade.

Features

  • Premium professional grade, manufactured to outlast cheaper diamond points
  • 4.0 mm round profile for versatile material removal and contouring
  • Diamond particles electroplated onto stainless steel for consistent, reliable abrasion
  • Medium Fine grit (120–140) for controlled stock removal with a refined finish
  • Standard 1-3/4" (44.5 mm) overall length matches popular industry bur lengths
  • 3/32" stainless steel shank fits standard handpiece collets
  • Suitable for stone carving, cleanup work, glass, ceramics, and metals

Notes

  • Always use water or a diamond lubricant when using diamond instruments of any kind to extend tool life and protect the work surface.
  • Do not exceed the maximum rated speed of 35,000 RPM.
