The Stihl hexa file has been designed with an innovative shape that complements the teeth of the 3/8 in hexa saw chain, providing professional and domestic users with a hassle-free way of sharpening the saw chain accurately. The Stihl hexa file's shape ideally matches the cutting tooth angle on the Stihl saw chain, making it easier for users to sharpen the depth gauge with speed and precision. With this convenient feature, users can save time while ensuring that the full chisel chain has a longer service life.
