Description

This tapered wheel diamond point does precise edge work and contour grinding on stone, glass, ceramics, and metals, and cleans up detail areas at the bench. The Diamond Supreme tapered wheel delivers controlled material removal in a 0.8 mm diameter by 4 mm width profile mounted on a standard 3/32" shank. Diamond particles are electroplated onto a stainless steel substrate, producing a durable, consistent cutting surface suited to detailed work across a range of hard materials.

Diamond Supreme diamond points are premium professional grade, manufactured to last many times longer than cheaper diamond points. Each instrument measures 1-3/4" (44.5 mm) in total length, identical to popular tungsten vanadium burs from Pfingst, Fox Germany, and Otto Frei Swiss, making them a direct drop-in replacement for existing handpiece setups.

Features

  • Tapered wheel profile for precise edge work and contour grinding
  • 0.8 mm diameter by 4 mm width
  • Diamond particles electroplated onto stainless steel for consistent grit distribution
  • Premium professional-grade construction for extended service life
  • Medium Fine grit (120–140)
  • Standard 3/32" stainless steel shank fits most flex-shaft handpieces and rotary tools
  • Uniform 1-3/4" (44.5 mm) length matches popular tungsten vanadium bur sizing
  • Suitable for stone carving, cleanup, glass, ceramics, and metals

Notes

  • Always use water or a diamond lubricant when operating diamond instruments of any kind.
  • Do not exceed the maximum rated speed of 35,000 RPM.
