|A new idea - sanding sticks which are tapered and half-round! They are available in 6 grits from #3 down to #6/0. One sit is flat and the other is half round for the inside of rings. Excellent for all precious metals and PMC. They have a total length of 9-1/4" with a sanding surface of 6". They also taper from 3/4" wide down to 5/16" wide at the tip.
The 2/0 grit corresponds to 500 mesh/grit
|EMERY is a hard, rock-like material consisting largely of corundum (aluminum oxide). Iron oxides are often mixed in giving it that familiar dark brown to black color. Emery is an aggressive abrasive, but due to the mixture of materials, it typically has a hardness of approximately 6-8.
