Manufactured to the same exacting standards as the rest of their equipment, Husqvarna's 3/16" Chainsaw Sharpener Round File is a great way to keep your chainsaws running at peak performance. It features an aggressive spiral cut tooth pattern that's less likely to load up like fine cut teeth, meaning it will leave an even, scratch-free cutting edge with minimal effort. | Husqvarna 3/16" Round Chainsaw File
