2-Pack 9"36 Teeth Carbide Tipped Blades for Brush Cutter, Trimmer, Weed Eater

What It Is

A 2-pack of 9-inch, 36-tooth carbide-tipped circular blades designed for brush cutters, string trimmers, and weed eaters. These blades are for heavy clearing of thick weeds, small saplings, brambles, and woody brush—not for regular grass or lawn trimming.

Fitment & Compatibility

Before buying, check three things:

• Arbor hole size: These blades have a standard 25.4mm (1-inch) center hole. Most straight-shaft brush cutters accept this, but some curved-shaft or older models use 20mm. Measure yours.
• Attachment system: These use a standard M10 x 1.25 left-hand thread nut (included). If your trimmer uses a different fastening method (e.g., pin spanner or bolt), they won’t mount.
• Machine power: Minimum 30cc engine or equivalent electric (40V+). Underpowered trimmers may stall or overheat. Not for standard string trimmer heads—only for dedicated brush cutter attachments or universal blade adapters.

Key Things to Know

• Carbide tips last long on woody material but are brittle—avoid hitting rocks, concrete, or metal; chips or breaks are not covered.
• Installation requires a left-hand thread nut (included). Tighten counterclockwise. Use the supplied wrench and lock the shaft with the included pin.
• Balance check is essential after mounting. An unbalanced blade vibrates severely and can damage the trimmer head or shaft. Spin by hand to verify.
• Grass/lawn use will dull them faster than standard nylon line—these are for rough clearing only.

Should You Buy It

Yes, if you need an affordable, durable blade for occasional heavy brush clearing on a compatible straight-shaft trimmer with sufficient power. Skip them if you only cut grass or have a small electric trimmer—you’ll get better results with standard trimmer line.
