Cylinder Diamond Bur – #836
1/16″ Friction Grip Shank bit for use in high speed engravers such as the NSK Presto.
Diamond head is .6mm in length and 1.4mm in diameter.
This bur is used to carve wood, stone, metal, eggs and more. It’s great for sanding ridges and small areas because of the cylinder shape.
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”.
