Drill Doctor 500x
This thing is awesome, I have now sharpened over 100 drill bits (it took a while) but they are all sharp now and cut through 1/8 in steel very quickly. I go through drill bits so quickly but never threw them away I just kept sharpening them on my grinding wheel it does an alright job but not nearly as good as this thing, now I’m wishing I hadn’t waited so long to get this thing. You have two degrees to choose from 118 and 135 degrees and then on top of that you can turn you drill bits into split point bits which allow you to drill without the bit walking (big bonus). Before I got the Drill Doctor I was burning bits up and causing the metal to become harder but with the Drill Doctor I’m turning all my drill bit into split point bits and it’s even drilling stainless steel it wasn’t as easy as drilling thick steel but it still did the job.
