Use in Engraver's Chuck XT1 (see "Related Products" below).
Apply Gesswein Stoning and Lubricating Oil on the stone’s sharpening surface prior to each use. This will prevent the pores of the stone from filling with material removed from the object being stoned.
India Stones are available in course, medium and fine grits. Use coarse grit for restoring badly worn cutting edges and for all sharpening not requiring a keen edge; use medium grit for producing an average edge on a broad range of tools, such as carving tools, milling cutters, lathe tools and die chasers; and use fine grit for producing sharper-than-average edges on gouges, reamers, taps and twist drills.
