Pyramid Point Tool

This tool is shown ground with 3 cutting edges, approximately 120° wide. The diagram on the top at the right shows the tool, looking down at one of the cutting edges. The diagram at the bottom at the right shows that tool rotated 90°, and the same cutting edge is now on the top.


This tool is one where reshaping the cutting surface can be onerous, and the Tormek BGM-100 Bench Grinding Mounting Set can be quite useful. When grinding on a high speed grinder, all the settings remain the same.

Notes & Comments
  • The late Bill Jones has a really good description of how to use this tool in his 1997 book, Further Notes from the Turning Shop.

  • David Reed Smith wrote really this article about the pyramid point tool. In it, he goes the making, sharpening, and use of it. Note how David modifes the handle, adding a notch to make it easier to sharpen on the Tormek.

  • Sean Rubino's video below shows how to make a point tool, and it is quite good.

    • The jig that Sean made is worth considering for sharpening this tool. If you do make one of these jigs, consider making it from metal (e.g., aluminum). And add a brass tipped set screw to help keep the tool from rotating in the jig when sharpening the other three faces.

      This jig would work well with the Tormek SVD-110 Tool Rest.
