Small Diamond Disc #825
This small disc is great for reaching into tight areas and sanding flat surfaces. It is just a little smaller than the 826 Large Diamond Disc
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”.
