Diamond Supreme Diamond Point- Round 4.0mm On 3/32" Shank

The Diamond Supreme Diamond Point in a 4.0 mm round profile delivers premium professional-grade performance for stone carving, cleanup work, glass, ceramics, and metals. Diamond particles are electroplated onto a stainless steel form, creating a precise, durable cutting instrument built 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 — making it a seamless fit in any professional setup. The 3/32" stainless steel shank ensures compatibility with standard handpiece collets used throughout the trade.

Always use water or a diamond lubricant when working with diamond instruments of any kind.
