Carbide Saw Sharpening Tips & Tricks

Are you getting upwards of 20 sharpenings on your saws?
Are you receiving the same edge life after service as when new?

If you answered “No” to these questions your saws may not be serviced properly. Saw teeth are rectangular. The dull or blunted cutting edge needs to be ground in a way that:

  • Removes the least amount of carbide
  • Does not prematurely reduce critical clearance angles
  • Keeps the shape of the tip proportionate

Serviced properly, you should be able to extend the life of your sawblade beyond more than 20 re-sharpenings in many applications.

Common Mistakes

  1. Grinding too heavily from the tip’s face. If your saws have a long, skinny strip of carbide after only 5-6 sharpenings then too much was ground away from the face.
  2. Failing to keep the shape of the tip proportionate. This can be achieved by grinding at a ratio of 1/3 from the face and 2/3 from the top, every time the saw is serviced.
  3. Not inspecting the dull blade. Does the resin build up on the teeth look equal on both sides? If not it could be an application issue but also that the saw's teeth are not centered.

The main benefits we strive for are:

  • To achieve the most service lives possible, resulting in the lowest applied tooling cost, on every blade we service.
  • To provide a serviced saw that performs as long as possible. More run time and less down time.
  • To return each saw to its original manufactured specifications. This includes blades of all brands and designs.
  • To provide troubleshooting services to help you work through application.
