Diamond Coated File
The diamond coated file is a 4mm (5/32″) diameter file. The teeth of the 4 and 6 tooth chains are coated with tungsten carbide and because of the hardness of this material a diamond coated file is required to sharpen the teeth. A standard chain saw file just won’t work. You can also use the he Diamond Coated File for our 8-tooth chain disc, keeping your manual hoof knife sharp and sharpening any chainsaw blade you may have.
