Brush Cutter Blade Kit, 10" 80T Carbide Tip, 9" 36T and 3-Tooth Carbon Steel Blades, Compatible with Stihl, Husqvarna, Ego, Oregon, Hitachi Trimmer (3 PCS with Accessories)

What It Is

This is a 3-piece brush cutter blade kit designed for clearing heavy grass, brush, and light woody vegetation. It includes a 10-inch 80-tooth carbide-tipped blade for dense material, a 9-inch 36-tooth blade for general brush, and a 3-tooth carbon steel blade for thick stalks and saplings. Intended for use with straight-shaft string trimmers converted to blade cutting.

Fitment & Compatibility

Before buying, verify your trimmer has a straight shaft and a compatible head that accepts universal blades (typically a 25.4mm or 20mm arbor hole—measure yours). This kit is marketed for Stihl, Husqvarna, Ego, Oregon, and Hitachi models, but it’s a universal fit for most straight-shaft trimmers with a standard blade mount. Check your trimmer’s manual for maximum blade diameter; 10 inches may exceed some smaller units (e.g., many 25cc trimmers max out at 8 inches). Also confirm your trimmer head uses a retaining nut and washer system, not a quick-load string head—some models require an adapter kit (sold separately). This is an aftermarket set, not OEM, so expect minor variations in hole alignment or thickness.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a blade nut wrench and a shaft lock tool (or a screwdriver to pin the gearbox). Swap takes 10-15 minutes if you’re handy.
• Safety first: Always disengage the engine and remove the spark plug wire before swapping. Wear heavy gloves—carbide tips are sharp and brittle.
• Blade selection: Use the 80T for thick grass/weeds, the 36T for mixed brush, and the 3-tooth for woody stems up to 1-inch diameter. Never use the 3-tooth on light grass—it’s aggressive and can kick.
• Common gotcha: The included washers and nut may not fit all arbor sizes. Have a standard M10x1.25 LH nut on hand if yours doesn’t match. Also, balance the blade after installation—an unbalanced blade vibrates and damages the gearbox.

Should You Buy It

If you need a versatile, budget-friendly blade set for clearing overgrown areas with a straight-shaft trimmer, this is a solid pick—especially for the price. It’s not for light trimming or curved-shaft units. Best for homeowners or semi-pro users who want three cutting options without buying separate OEM blades. Skip it if you need a perfect OEM fit or have a very small trimmer (under 30cc).
