Vevor 13A Drill bit sharpener
This machine is perfect for sharpening Metric or SAE 3-13 mm/1/2 inch. Far exceeds Dr. Doctor in accuracy and is much more accurate than hand sharpening. I have used it to sharpen a few bits, and it does an excellent job and great for split points. It is in excellent condition, and I'm selling it since I bought the Vevor 3-20 that I needed to sharpen larger bits from 1/2 inch -3/4
