What it does
- Holds your drill bit at the right angle so you get sharp, even edges every time you sharpen.
- Works with all standard drill bits up to 1/4 inch, so you keep your whole collection sharp and ready.
- Two bite angles in one jig; flip it over to switch between 61 and 59 degrees for different sharpening needs.
- Guides your bit straight and steady, so sharpening takes less practice and gives better results than freehand work.
- Made from durable 3D-printed material, so it lasts through years of workshop use without wearing out.
Sharp drill bits make your work faster and cleaner. This sharpening jig helps you sharpen your own bits on a bench grinder or angle grinder, so you spend less money on new ones and always have sharp tools ready to go.
The jig holds your drill bit in a groove that keeps it at the right angle while you grind. Grooves face up, and you hold the long part of the jig straight across from your grinder wheel. This steady position means you get a consistent angle on the tip every time. Your bit stays sharp longer because the angle is precise.
All SAE drill bits up to 1/4 inch fit snug in the grooves. Flip the jig over and you switch from a standard 61 degree bite to a more aggressive 59 degree bite, depending on what you need. One side stays with you through countless sharpenings, and it works on your bench grinder or in a vise with an angle grinder.
