Round Diamond Cutters – Burs for High Speed Engraving and Carving in High Speed Rotary Tools such as the NSK Presto.
Quality round sphere burs in sizes from 1 to 8.
They can be used on metal, glass, eggs, wood, tile and even stone. High speed carving tools and burs give you superior control over all other rotary tools for ultra precision work. Use these diamond bits for etching in glass, metal, bone, antler, wood, and virtually any other material. Diamond burs will often give you a softer cut compared to carbides and can also be used for sanding.
They are to be used in most high speed tools such as the NSK Presto, Ney Hurricane, Shofu Lab Z Air and any other that uses 1/16 shank friction grip burs.
How long will they last? This depends on the pressure applied and how “heavy” your hand is and your application. Many wood carvers use worn diamond burs for sanding even after they’ve been “worn out”. It is very important when using high speed tools to allow the speed of the tool to do the work and not be too “heavy handed”.
