Stump Grinder Teeth FAQ

Maximize Performance and Longevity

What are stump grinder teeth made of — and why does it matter?

Our stump grinder teeth are crafted from high-strength forged steel with brazed carbide tips, combining toughness and cutting precision. This proven construction offers outstanding wear resistance and extended life, even in rocky or high-impact environments.

How do I choose the right stump grinder teeth?

Choosing the right teeth depends on your machine, your job, and your soil:
Stump Size & Hardness: Larger, denser stumps need tougher teeth.
Soil Conditions: If you’re grinding in rocky or sandy terrain, choose impact-resistant styles.
Machine Type: Whether you’re running a self-propelled, tow-behind, or high-torque grinder — we have compatible teeth.
Speed vs. Longevity: Some teeth prioritize aggressive cutting; others are built for extended wear.
If you’re unsure what works best for your setup, just give us a call — we’re happy to help.

How do I maintain stump grinder teeth to extend their life?

– Inspect teeth before and after use for chips, cracks, or wear
– Rotate multi-edged teeth regularly
– Clean off dirt and sap, and store in a dry area to prevent rust
– Sharpen if the style allows — some designs support multiple sharpening cycles

When should I replace stump grinder teeth?

Replace your teeth if you notice:

– Slower cutting or rougher operation
– Excess vibration or unusual strain on your grinder
– Visible wear, rounding, cracks, or broken carbide

Timely replacement prevents further machine wear and keeps your jobs on schedule.

What types of stump grinder teeth do you offer?

We carry one of the largest inventories of stump grinder teeth in the U.S., with styles that are compatible with virtually every major grinder brand and tooth system — including round, square, straight, rotating, and more.

Whether you need heavy-duty dual-tip teeth, multi-position rotating teeth, or long-life solutions for rocky conditions, we’ve got it — in stock and ready to ship.

How can I get the most from my teeth?

– Inspect and rotate regularly
– Clean after use
– Replace or sharpen at the first sign of wear
– Small habits make a big difference in tooth performance and cost over time.
