The drill is an essential tool for woodworks, repairs and home DIY projects. But with frequent use, the drill bits get blunted and ineffective. The continued use of a blunt drill causes the drill holes to go all wrong or uneven, damages your materials, wears your arms out, and generally ruins the output quality of your projects.
If you don’t know how to sharpen your drill, or don’t have the gadgets to do that, you end up buying new drill bits every time your old ones get blunted. And that can only cost you more money than you ever need to spend. However, if you have a simple bench grinder in your workshop, you can sharpen the drill bits on your own—freehand without the use of any drill sharpening gadgets like drill jigs or drill doctors.
All you need for this process is your bench grinder and two bolt nuts to serve as an angle guide. This DIY basic drill sharpening guide will show you how to do the job using only your bench grinder and those two bolt nuts.
