Aluminum Oxide Round Combination Stone

Aluminum Oxide Stones Aluminum oxide stones excel at refining surfaces, offering a finer finish than silicon carbide stones. Their durability and ability to hold their shape well make them ideal for precision tasks such as sharpening, shaping, leveling, or deburring after machining. These stones are a good choice when a high-quality finish and accuracy are critical. Coarse and Fine Combination This stone combines a coarse side and a fine side on one stone. Whether multiple grits are required to do one job, or if one stone must handle multiple jobs, this aluminum oxide stone offers the convenience of two grits in one. Use the coarse side for fast material removal and the fine side for surface refining. Fine - 400 Grit Coarse - 120 Grit Dimensions 4" Diameter x 1" Thickness
