Drill Bit Sharpener

I have wanted to try re-sharpening drill bits for a long time. I think it would be a good way to reuse something instead of throwing it away too soon. I had seen one called the Drill Doctor on Youtube that has its own motor, but it was too expensive. I found a drill bit sharpener at Harbor Freight that was a reasonable price and decide to try it out.

You can buy it online through Amazon, but it costs more. Here's my affiliate link: https://amzn.to/2ExXew8

The sharpener is a grindstone with a jig attached. It works on 2 mm to 12.5mm bits. To use this, you need a drill that spins between 2000 and 3500 RPM. There's a typo on one side of the package that says it could work at 35000 RPM, but I don't think that would be safe. I used my drill press at 2100 RPM and it worked on my first try. It got the bit sharper, but the point and edges aren't perfect. I think I could get better at using it with more practice.

I saw a video on Youtube about a giant automated drill bit sharpener. It was really cool, but it is meant for much larger drill bits in an industrial environment. Here's the link: https://www.youtube.com/watch?v=jx_9GK3sF6g&t=4s
