4-Facet Drill Bit Grinding Jig for Precision Drill Bit Sharpening

The 4-Facet Drill Bit Grinding Jig is a precise tool for easy and symmetrical grinding of all 4 facets of your drill bit. This drill bit sander eliminates the need for an expensive machine like a Tormek sander with DBS-22 attachment, as sanding is done with a 180-grit sandpaper on a flat surface. With this jig, you can choose the rake angle that suits the diameter of the drill bit and the material to be drilled - soft material requires a higher angle than hard steel.
