CALPALMY Brush Cutter Blade Kit — 9" 20T & 36T + 10" 80T Blades with 1" Arbor Adapters, Carbide-Tipped Durability

CALPALMY Brush Cutter Blade and Adapter Kit supplies three carbide-tipped circular saw blades and two universal adapter sets to turn a 1" arbor straight-shaft trimmer into a durable brush-cutting tool.

If you need a single kit that handles thick grass, string, underbrush and small saplings, this CALPALMY bundle covers a wide range of cutting tasks. The set includes 9" blades in 20- and 36-tooth profiles plus a 10" 80-tooth fine blade, all made from manganese steel with carbide tips, plus two adapter kits for fast installation on most straight-shaft trimmers (1" arbor). It’s built for landscapers, homeowners clearing overgrown lots, and DIYers upgrading a weed eater for heavier work.

How do the different blade tooth counts affect cutting performance?

Tooth count changes how aggressively and smoothly a blade cuts: fewer, thicker teeth remove material fast and resist clogging; higher tooth counts make cleaner cuts in lighter vegetation and thin wood. Choosing the right blade depends on the job—fast clearing versus precise trimming.

• 9" x 20T: large, widely spaced teeth for chopping heavy brush and small saplings.
• 9" x 36T: medium tooth density for mixed tasks—thicker grass and light woody stems.
• 10" x 80T: fine-tooth blade for smooth cuts on string-like growth, finishing work, and edging.

Will these blades fit my trimmer or brush cutter?

The kit is designed for straight-shaft trimmers and cutters that accept a 1" arbor; it includes two universal adapter sets to match common shaft setups. It’s compatible with many gas and electric models, though not compatible with ECHO SRM-series machines.

• 1" arbor specification—fits most straight-shaft units.
• Dual adapter sets include washers, collar nuts, and wrenches for secure mounting.
• Check your model’s manual if you have a curved shaft or proprietary mounting system.

What are the blades made of and how durable are they?

These blades are stamped from wear-resistant manganese steel and finished with carbide-tipped teeth for long edge life against gritty vegetation. The materials resist deformation during heavy work, though proper use and routine sharpening will maximize service life.

• Manganese-steel body for toughness under load.
• Carbide tips maintain sharpness on abrasive stalks and small wood.
• Balanced design reduces vibration for smoother cutting and longer tool life.

How simple is installation and what comes in the adapter kits?

Installation is straightforward: remove the existing head or string assembly, attach the correct adapter stack to match your shaft, fit the blade, and torque the collar nut. The kit includes clear hardware pieces so you can swap blades in the field.

• Two universal adapter kits with thrust washers and collar nuts.
• Included wrenches speed up blade changes on-site.
• No special tools beyond the supplied wrench set are required.

Who is this for? Landscapers, property owners, and weekend warriors who want one versatile blade kit to handle clearing, trimming, and finishing tasks will benefit most. If you own a straight-shaft trimmer with a 1" arbor and need durable cutting performance across thick grass, vines, underbrush and light tree limbs, this CALPALMY kit gives you three tooth profiles and the adapters to get to work quickly. For machines with nonstandard arbors or models explicitly excluded (such as the ECHO SRM series), verify fit before purchase.
