Sharpen a Wide Variety of Stump Grinder Teeth

The Universal Stump Grinding Fixture is designed to sharpen many common stump grinder tooth styles, including:

• Standard stump grinder teeth
• Straight teeth
• Right-hand teeth
• Left-hand teeth
• Vermeer round body stump grinder teeth
• Teeth with shank sizes from 1/2″ to 7/8″

This flexibility makes the fixture an excellent solution for businesses servicing multiple stump grinder brands and tooth configurations.

 

Sharpens Both the Top Radius & Flat Face

The fixture allows operators to sharpen two critical cutting surfaces:

• Top radius of the tooth
• Flat face of the tooth

Maintaining both surfaces helps ensure:

• Improved cutting efficiency
• Better tooth performance
• Reduced machine strain
• Extended tooth life
• Consistent stump grinding results

Proper sharpening helps restore the original cutting geometry needed for effective stump removal.

 

Special Plated Radius Grinding Wheel Included

The fixture includes a specially designed plated radius grinding wheel that simplifies the sharpening process and improves productivity.

Benefits include:

• No wheel dressing required
• Cleaner operation than traditional green grinding wheels
• Faster setup times
• Consistent tooth profiles
• Improved sharpening accuracy
• Most teeth can be sharpened up to 5 times.

The plated wheel is designed to match the radius profile of the stump grinding tooth, making sharpening straightforward and repeatable.

 

Fast & Efficient Sharpening

Using the fixture is simple:

1. Position the radius of the tooth into the radius of the grinding wheel.
2. Sharpen the top radius and flat face.
3. Restore the cutting edge geometry.

Most stump grinder teeth can be sharpened in less than two minutes per tooth. This allows operators to reduce downtime while keeping stump grinding equipment performing at its best.

The Universal Stump Grinding Fixture mounts directly to the AV-56 Stump Bit Grinder using the 1″ plug located on the Thorvie saddle assembly.
