The CMT 298.250.20 Carbide Trimmer Blade from CMT is a purpose-built 10-inch brush cutter saw blade engineered for clearing grass, bushes, and small trees. Featuring 20 alternating top bevel (ATB) teeth tipped with tungsten carbide (HW grade), this trimmer blade delivers clean, aggressive cuts through dense vegetation and woody growth. With a 25.4mm bore diameter that also accepts 20mm arbors, it fits a wide range of brush cutter machines and makes a dependable choice for land clearing, overgrowth removal, and seasonal vegetation management.

Key Features

• 20-tooth ATB geometry (8 deg. alternate top bevel) - the alternating top bevel tooth profile shears through grass, brush, and small woody stems efficiently, reducing tearing and leaving cleaner cuts on each pass.
• Tungsten carbide (HW) tooth material - carbide tips stay sharp far longer than steel under tough outdoor cutting conditions, meaning fewer blade changes and more consistent performance through heavy vegetation.
• 10-inch (254mm) blade diameter - the large cutting circle maximizes coverage per swing, making it well suited for clearing wide swaths of overgrowth with a brush cutter.
• 25.4mm bore diameter (fits 20mm arbors) - dual-bore compatibility allows this blade to mount on a broader range of brush cutter spindles without requiring adapters.
• 0.079-inch kerf thickness with 0.055-inch plate - the thin kerf-to-plate ratio reduces material waste and minimizes resistance through dense brush, demanding less effort from the machine motor.
• 2 deg. cutting (hook) angle - the low hook angle promotes controlled, aggressive engagement with vegetation without grabbing or binding, supporting safer operation through mixed-growth terrain.

Why This Product

• Designed specifically for brush cutter machines tackling grass, bushes, and small trees, this blade addresses the demands of land clearing work where a standard trimmer line or general-purpose blade would fall short.
• Carbide-tipped ATB teeth combine durability with cutting efficiency, making this blade a practical investment for property owners and landscaping professionals who need reliable performance across repeated heavy-use sessions.
• The 25.4mm bore with 20mm compatibility means fewer fitment headaches when switching between machines - one blade can serve multiple brush cutters in a fleet or shop.
• At 20 teeth with a thin 0.079-inch kerf, this blade balances cutting speed and motor load, making it a smart match for clearing applications where smooth, continuous cutting matters more than ultra-fine finish.

Frequently Asked Questions

What type of machine is this blade designed to fit?

This blade is designed for use with brush cutter machines. Its 25.4mm bore diameter is also compatible with 20mm arbors, giving it broad fitment across common brush cutter spindle sizes.

What materials can this trimmer blade cut through?

According to CMT product data, this blade is intended for cutting grass, bushes, and small trees. It is not designed for wood panel products or construction lumber - it is specifically a garden and land-clearing trimmer saw blade.

What does ATB tooth geometry mean for this type of cutting application?

ATB stands for Alternate Top Bevel, meaning each tooth is angled in alternating directions. This geometry allows the teeth to shear through plant fibers and woody stems efficiently, which helps produce cleaner cuts and reduces the tendency to bind when clearing brush and overgrowth.

Is the existing product description that references edge banding or MDF accurate for this blade?

No. This blade - CMT model 298.250.20 - is a brush cutter trimmer blade for clearing grass, bushes, and small trees. It is not an edge banding trimmer blade. Always refer to the specifications and application data shown here when selecting the correct blade for your cutting task.
