Stump Grinder Sharpening Tool

Yes! With ArborEdge’s patented diamond coated “Stump Tooth Sharpening Tool”, you can resharpen your stump grinder teeth in minutes saving you thousands of dollars on replacing them. By simply using a portable or corded die grinder that accepts a ¼ in shank, you can sharpen your stump grinder teeth in the field on the machine or back in the shop in a vice.

There are two ways to sharpen your stump grinder teeth. First you can sharpen the teeth directly on the stump grinder. Our tools were designed for easy, in the field use so you can sharpen them without the hassle of removing them from the equipment and having to reinstall them. This would require a battery-operated grinding tool that spins the tool at 10,000 RPM’s or faster. You can also remove the teeth from the equipment, put them in a vice and sharpen them back in the shop. A corded or cordless tool can be used in this environment. We recommend this process if you have two sets of teeth that you are rotating. When using the tool be sure to let the diamonds do the work, apply very little pressure. Diamonds are great at cutting carbide and letting them do the work at their pace will prolong the life of your tool.

More frequent sharpening’s will maintain a sharp edge on your stump grinder teeth and give you the longest life from your stump grinder tool. A stump grinder tooth that is significantly worn is not worth wearing out your tool to bring it back. Regularly inspect your teeth for wear and keep them sharp. Most stump grinder teeth have a significant amount of carbide, allowing you to sharpen them numerous times before having to be replaced. This is where your biggest cost savings will be. Eventually you will need to replace damaged or excessively worn stump grinder teeth.

Always wear PPE including eye protection and a dust mask (N95). Carbide dust is a carcinogen. When sharpening on your equipment, ensure the machine is powered off, and the wheel is locked (if required).

We recommend any die grinder that can run at 10,000 RPMs or higher. Most of the good die grinders on the market are also considered “sheetrock cut out tools” (example). All of the cordless tool manufacturers make a similar tool. There are also very inexpensive corded tools on the market as well. ArborEdge recommends running your sharpening tool at a minimum of 10,000 RPM’s, but faster is always better when it comes to carbide cutting. Additionally, make sure your tool will accept a ¼ inch diameter shank.  This is the shank size that comes on all ArborEdge cutting tools.

The frequency of replacing stump grinder teeth depends on usage. Generally, teeth should be replaced when they become dull, damaged, or worn out, which could be every few months to a year, depending on the intensity of use. To extend the lifespan of stump grinder teeth resharpen before you replace them.
