Modern Abrasive Combination Fine/Coarse Grit Bench Stone, Oil-Filled Aluminum Oxide #112A, 4″ x 1-3/4″ x 5/8″

When more than one grit size is necessary to resharpen a cutting edge, a craftsman will often use a combination stone to lessen both the expense and the inconvenience of using two single grit stones. Use a silicon carbide stone for sharpening quickly or an oil-filled aluminum oxide stone for restoring a long lasting edge.

Features:

• Aluminum oxide stones are used for finishing of hardened steel.
• Silicon carbide stones are used for finishing of soft steel, cast iron, non ferrous metals as well as for edging of cemented carbides.
