AS-H GENERAL PURPOSE POLISHING STONE

General Purpose Polishing Stone · Aluminum Oxide · Soft Structure with Fast Breakdown

AS-H is similar to the AM-K finishing stone but is slightly softer and works well on tool steels as well as non-ferrous materials. It conforms quickly to varied pre-shaped surfaces. We suggest always using lubricants like our Premium Stoning Oil or BORI-LUBE 10 with this stone. AS-H polishing stones are more suitable for hand stoning with one of our Hand Holders but may be used with reciprocating profilers like our U-Lap and Turbo-Lap Air Profilers.

Available in 100-1200 grit and a wide variety of sizes.
Also available in a kit.
