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

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.
