2 Pack 7" x 16T Carbon Steel Chainsaw Brush Cutter Blade for Weedeater +1 Round Files + 2 Set Adapter Kits for Cutter, Trimmer, Weed Eater

What It Is

This is a 2-pack of 7-inch, 16-tooth carbon steel brush cutter blades designed for clearing thick grass, weeds, and light brush on string trimmers and weed eaters. It includes two round files for sharpening and two adapter kits to fit various trimmer heads.

Fitment & Compatibility

Before buying, check three things:

1. Shaft hole size: The adapter kits include bushings, but verify your trimmer’s shaft diameter (typically 20mm, 25.4mm, or 1-inch). The blades have a 25.4mm center hole.
2. Trimmer type: Works on straight-shaft gas trimmers (e.g., Echo, Husqvarna, Stihl, Ryobi) with a brush cutter attachment. Not for curved-shaft or electric trimmers.
3. Mounting system: The adapter kits replace the standard string head. Ensure your trimmer has a removable head and a compatible arbor (most standard square or hex drives fit). No OEM guarantee—aftermarket fit requires measuring your existing head’s bolt pattern and shaft.

Key Things to Know

• Quality: Carbon steel is durable for light brush but will dull faster on woody stems or rocks. The included files are basic—upgrade to a proper flat file for better sharpening.
• Installation: Moderate difficulty. You must remove the string head, install the adapter, and tighten the blade with a wrench. Watch for reverse-thread nuts on some models (e.g., older Stihl).
• Gotchas: The 7-inch blade can cause kickback if you hit a solid object. Always wear eye and leg protection. The adapter kits may not fit all trimmer models—double-check your shaft’s drive shape (hex vs. star vs. square) before buying.
• Maintenance: Sharpen after every 2-3 uses for best cut. Replace if teeth chip or crack—carbon steel can snap under heavy impact.

Should You Buy It

Buy this if you need a budget-friendly, multi-pack option for clearing dense weeds and light brush on a standard straight-shaft gas trimmer, and you’re comfortable with basic mechanical installation. Skip it if you have a curved-shaft trimmer, need a blade for heavy woody brush or stumps, or want a guaranteed OEM fit without measuring.
