Kohnkdllc Brush Cutter & Weedeater Blade Kit — 10in 80T Carbide, 10in 3T Carbon, 9in 20T with 2 Universal Adapters

Kohnkdllc's kit combines three durable 10" and 9" cutting blades plus two universal adapter sets and files for fast trimming, brush clearing, and light stump cutting with compatible straight-shaft trimmers.

This complete replacement and upgrade pack fits many straight-shaft string trimmers and brush cutters with 25.4mm (1") or 20mm arbors. The set groups a 10" 80-tooth cemented-carbide tip blade for dense brush, a 10" 3-tooth carbon-steel blade for heavy grass and light saplings, and a 9" 20-tooth chainsaw-style blade for aggressive cutting. Two adapter kits and four round files are included so you can install and maintain the blades without hunting for extra parts.

Which cutting tasks does each blade handle best?

Each blade in the kit is tuned for a different job: the 80T carbide tip excels at thick brush and abrasive conditions, the 3T carbon steel clears tall grass and coarse weeds quickly, and the 20T chainsaw-tooth blade bites into small trunks and woody stems. Choosing the right blade reduces wear and improves cutting speed.

• 10" 80T carbide tip: optimized for brush, thorny plants, and abrasive soil exposure.
• 10" 3T carbon steel: fast clearing of tall grass, reed, and light saplings.
• 9" 20T chainsaw tooth: aggressive cutting of woody stems and resections.

How do I know these blades will fit my trimmer or cutter?

The kit includes two adapter sets designed to cover common straight-shaft trimmer arbors: 25.4mm (1") and 20mm. Each adapter kit contains the thrust washers, rider plates, lock nuts, and small tools you need for a secure fit. Verify your machine's shaft diameter and thread pattern before installing.

• Includes two adapter kits for 25.4mm (1") and 20mm arbors.
• Supplied rider plates, thrust washers, lock nuts, and small wrenches for installation.
• Check your trimmer manual or measure the arbor to confirm compatibility.

What material and durability features do these blades have?

The blades use manganese steel in combination with cemented-carbide tips for wear resistance and impact strength. Carbide teeth retain sharpness longer in abrasive environments while the carbon-steel 3T blade resists bending under heavy grass loads. Regular filing with the included round files extends cutting life between replacements.

• Manganese steel base for toughness and impact resistance.
• Cemented-carbide tips on the 80T blade for abrasion resistance.
• Four round files supplied for on-site sharpening and upkeep.

Who is this kit designed for?

This Kohnkdllc blade kit is for homeowners, landscapers, and property managers who need a flexible set of cutting tools to tackle a variety of vegetation: from overgrown lawns and tall weeds to thick brush and small trunks. It’s best for users of straight-shaft trimmers or brush cutters with 20mm or 25.4mm arbors who want quick blade changes, a durable carbide option, and the hardware to mount and maintain blades on their own. Always wear appropriate protective gear and confirm adapter fit before operation.
