Brush Cutter Blade Kit, 9" 20T Chainsaw Tooth and 10" 80T Carbide Tip, Compatible with Stihl, Husqvarna, Ego, Oregon, Hitachi Trimmer (2 PCS with Accessories)

What It Is

This is a 2-piece brush cutter blade kit designed for clearing heavy weeds, brush, and saplings. It includes a 9-inch, 20-tooth chainsaw-style blade for dense woody material and a 10-inch, 80-tooth carbide-tipped blade for thick grass and light scrub. It’s marketed for use with string trimmers converted to brush cutting, not for standard lawn mowers.

Fitment & Compatibility

This is not a mower blade—it’s a trimmer accessory for brush-cutting heads. Before buying, check:

• Arbor size: Most trimmers use a 25.4mm (1-inch) or 20mm arbor. This kit likely fits 25.4mm; verify your trimmer’s shaft diameter.
• Trimmer type: Compatible with Stihl, Husqvarna, Ego, Oregon, and Hitachi models that accept universal brush cutter blades. Ego-branded blades may not fit older Ego trimmer heads without an adapter.
• Guard requirement: You must have a brush-cutting guard (not the standard string trimmer guard) installed on your trimmer. Without it, operation is unsafe.
• Speed rating: Confirm your trimmer’s RPM is within the blade’s rated limit (usually around 8,000–10,000 RPM). Exceeding can cause blade failure.

Key Things to Know

• Material quality: The carbide-tipped blade is durable for abrasive grass, but the chainsaw tooth blade is steel and dulls faster on rocky soil or roots.
• Installation: Requires a 14mm socket and wrench. Reverse-thread nuts are common on some trimmers—check rotation direction before tightening.
• Safety: These blades can throw debris at high speed. Always wear eye and leg protection. Do not use on a standard string trimmer without a brush-cutting head.
• Balance: After installation, spin the blade by hand to ensure it’s centered. An unbalanced blade vibrates heavily and damages the trimmer shaft.

Should You Buy It

Buy this kit if you need a budget-friendly, dual-blade setup for occasional brush clearing on a compatible trimmer and already have a brush-cutting guard. Skip it if you’re clearing heavy woody brush daily—invest in a single, higher-end carbide blade. Not for standard lawn mowers.
