Brush Cutter Blade Kit, 9in 36T Carbon Steel Disc, 9in 20T Chainsaw Tooth Blade, 6-Blade Razor Head, with Adapter Kits Compatible with Stihl, Ego, Oregon, Hitachi Trimmer (3 PCS with Accessories)

What It Is

This is a 3-piece brush cutter blade kit for string trimmers converted into brush-clearing tools. It includes a 9-inch 36-tooth carbon steel disc, a 9-inch 20-tooth chainsaw tooth blade, and a 6-blade razor head, plus adapter kits—designed for heavy weeds, saplings, and overgrown brush.

Fitment & Compatibility

Before buying, confirm your trimmer’s shaft type (straight vs. curved) and drive system (direct drive vs. gear head). The included adapter kits are marketed for Stihl, Ego, Oregon, and Hitachi trimmers, but not all models—check your trimmer’s arbor size (typically 20mm or 25.4mm) and mounting hole pattern. This is an aftermarket kit, not OEM, so verify that your trimmer’s RPM rating exceeds the blade’s max speed (usually printed on the blade). Measure your trimmer head’s clearance—these 9-inch blades require ample guard clearance and may not fit compact trimmers.

Key Things to Know

• Quality: Carbon steel is durable but dulls faster than carbide-tipped blades; expect to sharpen or replace more often.
• Installation: Moderate difficulty—requires removing the trimmer head and securing the blade with a locknut. The adapter kit may need shims for a snug fit on non-standard arbors.
• Common gotchas: The chainsaw tooth blade is aggressive and can kick back on thick saplings; always use a full-face shield and heavy gloves. The 6-blade razor head is best for light brush—don’t use it on woody stems over ½ inch.
• Noise/vibration: These blades are louder and cause more vibration than string; check your trimmer’s vibration dampening.

Should You Buy It

Buy this if you need a budget-friendly, versatile brush-cutting setup for occasional heavy clearing on a compatible straight-shaft trimmer. Skip it if you want OEM fitment, need carbide longevity, or have a low-RPM trimmer—stick with a single-purpose blade.
