12-Piece Chainsaw Chain Sharpening Set. Chainsaw files last longer. Assorted sizes: 5/32", 3/16", 7/32". Sharpen chainsaw blades quickly and easily.

Made from high-hardness emery, a hard and coarse mineral, this sharpener is a fine natural abrasive for metal stripping, descaling, and deburring. It makes sharpening an easy and efficient task. The package includes six 3x4mm stones, three 3x4.8mm stones, and three 3x5.5mm replacement stones. It can be used to sharpen the chains of both gas and electric chainsaws. This makes sharpening much easier since you don't need to disassemble and assemble a new chain; you can sharpen your chainsaw to like-new condition in just a few minutes. Using a sharpener to sharpen your chainsaw chain will cut wood with less effort because the chain will make a cleaner cut with sharper blades. The sharpening is excellent, and the sharp chain cuts quickly and relatively straight. A sharp chain will prolong the life of the chainsaw engine.
