HK 2 Pack 9" x36T Carbide Tip Brush Cutter Blades Weed Eater Blades for Brush Cutter, Trimmer, Weed Eater, Compatible with Husqvarna, Stihl, Fsx, and More

What It Is

This is a two-pack of 9-inch, 36-tooth carbide-tipped brush cutter blades designed for heavy-duty clearing of thick grass, weeds, briars, and small saplings. It fits universal brush cutter and trimmer heads, including models from Husqvarna, Stihl, and FSX.

Fitment & Compatibility

Before buying, verify three things: blade diameter (must be 9 inches), arbor hole size (typically 25.4mm or 20mm—measure yours), and attachment type (most use a center bolt or locking pin). These are aftermarket blades, not OEM Husqvarna or Stihl parts, so they may not fit all quick-release or proprietary heads. Check your trimmer’s manual for “blade-compatible” heads—standard metal blade adapters work. Not for standard lawn mower decks; only brush cutters and string trimmers rated for blades.

Key Things to Know

• Carbide tips last 3–5x longer than steel blades on abrasive weeds and woody growth, but can chip if you hit rocks or metal.
• Installation is moderate—requires removing the trimmer head and using a blade nut (often reverse-threaded). A locking tool or hex key is usually needed.
• Common gotcha: these blades are aggressive and can bog down underpowered trimmers (under 25cc). Use on units rated for 9-inch blades.
• Balance check recommended—aftermarket blades may need minor balancing to reduce vibration; run a quick spin test before heavy use.

Should You Buy It

If you own a compatible brush cutter (25cc+) and regularly tackle thick, woody vegetation, this two-pack offers solid value for the price. It’s not for light grass trimming or standard lawn mowers, but for heavy-duty clearing, it’s a cost-effective upgrade that saves frequent blade swaps.
