Finishing Point Carbide #7903
The 7903 is 3.6mm long .005 of an inch on the tip, which makes this the finest tip carbide. This carbide is great for scrimshaw (detailed lines on ivory, horn and bone) but also works on metals. The finishing burs also sand and smooth the surface as you carve.
Be extra careful when inserting into the collet, the tip is very fragile and could snap off. It is best to use needle nose pliers when inserting and removing the bur.
For use in high speed tools such as the NSK Presto and others requiring friction grip, 1/16″ shank burs.
