FITS MOST STRAIGHT SHAFT TRIMMERS - This Chainsaw Tooth Brush Cutter Blade w/ included file fits most straight shaft trimmers, and is not compatible with curved shaft or electric trimmers. It features a 1-inch arbor hole and includes a 20mm bushing for versatile fit.

CONVERSION KIT SOLD SEPARATELY: A conversion kit is required for setups with a trimmer head. No kit is needed if your trimmer is already configured as a brush cutter. Check compatibility with your trimmer manufacturer and obtain the proper adapter for safe installation.

CHAINSAW TEETH FOR HEAVY DUTY JOBS - Cuts like a chainsaw through saplings, thick brush, weeds, grass, and small trees up to 2.5” thick. Its 20 chainsaw teeth spin at up to 10,000 RPM for aggressive & fast cutting.

LARGER 9IN BLADE FOR HEAVY DUTY TRIMMERS - The 9in blade covers more area with each pass, making it ideal for tougher brush and thicker growth. Built with 20 sharp chainsaw teeth, it performs best on higher horsepower trimmers (35cc+) and larger guards to handle demanding work.

COMPACT 7IN BLADE FOR MAXIMUM CONTROL - The 7-inch blade offers better control and maneuverability in tight spaces. It’s equipped with 14 sharp chainsaw teeth, and works best on low to mid range trimmers (25-30cc) or those with a smaller guard.

INCLUDED FILE FOR EASY MAINTENANCE - The 3/8 pitch chain can be easily sharpened using the included 13/64" file, ensuring lasting performance and clean cuts.
