2Pcs 9" x 36 Teeth Carbide Tipped Blades for Brush Cutter, Weed Eater, Trimmer (Without Adapter Kit)

What It Is

This is a set of two 9-inch, 36-tooth carbide-tipped blades designed for brush cutters, weed eaters, and string trimmers. They are intended for heavy-duty clearing of thick weeds, brush, and small saplings, not for fine grass trimming.

Fitment & Compatibility

Before buying, verify these three things:

• Mounting hole size: These blades come without an adapter kit, so you need to check your trimmer’s arbor size (typically 20mm, 25.4mm, or 1 inch). If your trimmer uses a specific adapter or requires a different hole shape, these won’t mount without purchasing a separate adapter.
• Trimmer head type: They are for straight-shaft trimmers and brush cutters with a metal blade-capable head. Not for curved-shaft or standard string-only heads.
• Blade size: 9 inches is common for mid-to-heavy-duty brush cutters. Measure your existing blade or check your manual to confirm clearance under the guard.

This is an aftermarket part, not OEM. No specific brand/model list is provided, so measure first.

Key Things to Know

• Carbide tips are durable but brittle: They hold an edge far longer than steel, but can chip if you hit rocks, concrete, or metal fencing. Avoid heavy impact.
• Installation requires an adapter kit (sold separately): If your trimmer uses a specific mounting system (e.g., Stihl FixCut, Ryobi), you may need to buy that adapter. This blade is just the blade.
• Balance is critical: After mounting, spin the blade by hand. If it wobbles, you’ll get vibration and poor cutting. You may need to balance it with a file or re-mount carefully.
• Safety gear is mandatory: Use eye protection, long pants, and boots. A blade throw can be dangerous if the blade or adapter fails.

Should You Buy It

Buy this if you have a straight-shaft brush cutter with a standard arbor (and you already have or can buy the correct adapter), and you need an aggressive, long-lasting blade for heavy brush and saplings. Skip it if you need a universal fit, or if your trimmer uses a proprietary adapter system—you’ll spend more on adapters than the blade is worth.
