Valve grinding compounds.

3M oil mixed

3M valve-grinding compounds are a product of the laboratories of the world’s largest manufacturer of surface coated abrasives. Superior equipment for grading and testing abrasive materials makes it possible to deliver a more uniform quality of valve grinding compounds than ever before offered to the trade.

3M valve grinding compounds are made exclusively from silicon carbide. Silicon carbide is a mineral next and hardness to a diamond. This gives unusual cutting paower to these compounds.

3M valve grinding compounds must not be confused or connected with any other valve-grinding compounds on the market today. Laboratory tests prove that 3M compounds have these outstanding qualities.
