What It Is

This is a 2-pack of 9-inch, 36-tooth carbide-tipped brush cutter blades designed to replace standard weed eater string on gas or electric trimmers. It’s meant for clearing heavy vegetation like vines, thick weeds, small bushes, and saplings—not for regular grass trimming.

Fitment & Compatibility

Before buying, check three things:

• Shaft type: Works with straight or curved shaft trimmers, but only if your trimmer accepts universal blades (most do with the included adapter kit).
• Arbor size: The universal adapter kit fits 20mm, 25.4mm, and 1-inch (25.4mm) center holes—common on most trimmers. Measure your trimmer’s arbor hole; if it’s smaller than 20mm, this won’t fit.
• Trimmer power: Not for low-power electric trimmers (under 15cc gas or 500W electric). Use on gas trimmers 25cc+ or high-torque electric models to avoid bogging or damage.

Key Things to Know

• Installation is straightforward but requires removing the string head and mounting the blade with the provided adapter plate, lock nut, and spacer. No special tools beyond a wrench.
• Carbide tips last longer than steel blades but can chip if you hit rocks or concrete. Avoid contact with hard surfaces.
• Safety first: A blade throws debris farther than string. Always wear eye protection, long pants, and boots. Use the trimmer’s guard if it has one.
• Balance check: After installing, run the trimmer at low speed to feel for vibration. Unbalanced blades can damage your trimmer’s shaft or clutch.

Should You Buy It

If you need to clear dense brush, vines, or small saplings and have a mid-to-large gas trimmer (or a high-torque electric), this 2-pack is a cheap, functional upgrade over string. But if you primarily trim grass or have a small electric trimmer, stick with string—this blade will overload your machine and be overkill for light work.
