This video shows how to sharpen a HSS drill bit using a diamond coated file. These files are inexpensive and can be used to sharpen most items. It’s not always possible to use a bench grinder to sharpen drill bits so this is a quick and effective way of sharpening the drill bit so that you can drill metal with ease. The important thing is keeping the included angle of the drill bit at 118 degrees, which can be difficult if using a bench grinder.
