9" x 36 Teeth Carbide Tipped Blades & 9" x20T Carbon Steel Round Chainsaw Tooth Blades & 10" x 80T Brush Cutter Trimmer Blades with Adapter Kit

What It Is

This is a multi-blade kit that includes three different cutting attachments: a 9” carbide-tipped blade (36 teeth), a 9” carbon steel chainsaw-style blade (20 teeth), and a 10” brush cutter blade (80 teeth), plus an adapter kit. It’s designed for clearing heavy brush, saplings, thick weeds, and overgrown grass on string trimmers and brush cutters.

Fitment & Compatibility

Before buying, check these specifics:

• Arbor size & adapter – The adapter kit is meant for common trimmers (typically 1” or 20mm arbor holes), but verify your machine’s shaft diameter and drive plate pattern. Not all trimmer heads accept a blade adapter.
• Machine power – These blades are heavy (especially the 80T blade). They require a straight-shaft, high-torque trimmer or brush cutter (e.g., 25cc+ gas models). Avoid using on small electric trimmers – risk of motor burnout or unsafe kickback.
• Deck size – Not applicable (these are for handheld trimmers, not riding mowers). Measure your trimmer’s guard clearance: the 10” blade needs at least 11” of guard opening to avoid binding.
• OEM vs aftermarket – This is a universal aftermarket kit. No OEM-specific fitment; you may need to modify or buy additional washers for a secure mount.

Key Things to Know

• Installation difficulty – Moderate. You’ll need to swap the trimmer head for a blade adapter (included). Follow your machine’s manual for loosening/tightening the nut; use thread locker if recommended.
• Blade selection – Use the 20T chain blade for saplings (up to 2”), the 36T carbide blade for heavy brush/roots, and the 80T blade for dense grass/weeds. Mixing them on the same machine is fine, but each requires rebalancing.
• Kickback risk – The 80T blade is aggressive; always use a full-face guard and keep the blade below waist level. Never use a bump-feed head with these blades.
• Durability – Carbide-tipped teeth hold an edge longer than carbon steel, but the 20T blade will dull faster on rocky soil. Replace if any teeth chip or crack.

Should You Buy It

Buy this kit if you need a versatile, budget-friendly solution for clearing thick brush, saplings, and overgrown weeds with a gas-powered straight-shaft trimmer. It’s right for homeowners or semi-pro users who want one set of blades for multiple jobs. Skip it if your trimmer is electric or if you need a single dedicated blade for professional daily use.
