Aluminum Oxide 6" x 5/8" Triangular File

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. Oil-Filled These Aluminum Oxide Stones are filled with oil in manufacturing, reducing the need for additional oil to be applied during use.
