When used with a bench grinder, a drill bit sharpening jig helps the operator keep the bit at a consistent angle for grinding the bit. The jig attaches to the grinder's tool rest, and can be adjusted for various types or bits, or to create a more or less aggressive cutting angle. No twisting of the bit is necessary, as only the tip of the bit needs to be sharpened.

Skill level:

  • Bench grinder with tool rest

  1. 1

    Mount the jig on the tool rest so that the angled end of the jig is parallel to the face of the grinding wheel. Clamp the jig in place with the C-clamp.

  2. 2

    Adjust the angle of the tool rest (with the jig attached) so that the tip of the drill bit is flat against the grinding wheel.

  3. 3

    Turn on the grinder. Hold the bit firmly against the side of the jig and ease it forward until it engages the grinding wheel.

  4. 4

    Ease the bit forward, raising the tip simultaneously until you complete cutting the entire face of the land, or the cutting tip.

  5. 5

    Repeat the previous step with the opposite land.

  6. 6

    Inspect the tip of the bit. If the two lands are not the same width, regrind the shorter land until the two are of the same length.

Tips and warnings

  • When cutting the lands, do not twist the bit.
  • When working with power tools, always wear appropriate safety equipment, including safety glasses.
