CALPALMY 9" 20T Brush Cutter Blades 2-Set — Carbon Steel Circular Blades with 3 Files & 4 Washers for Straight-Shaft Trimmers

These CALPALMY 9" 20-tooth brush cutter blades kit delivers a ready-to-use trimming solution: two carbon-steel circular blades, three sharpening files, and four washers for fast installation and long-lasting cutting performance.

Designed for straight-shaft trimmers and brush cutters from common brands, this 2-set blade kit provides a tough, heat- and rust-resistant cutting wheel that slices through underbrush, thick weeds, small branches, and stumps more efficiently than regular mower decks. The package includes accessories to mount and maintain the blades so you can get back to work quickly without hunting for spare parts.

How do these blades fit my trimmer or brush cutter?

The blades have a 1" arbor hole and a 9" diameter, making them compatible with many gas and electric straight-shaft trimmers. They are intended for use on models from well-known manufacturers that support circular saw-style cutter wheels, up to recommended maximum RPM limits.

• 1" arbor diameter to match standard straight-shaft spindles.
• 9" overall diameter for close trimming and clearance in tight areas.
• Compatible with many Husqvarna, Stihl, Ego, Oregon, Hitachi straight-shaft units (verify your model manual).
• Rated for high-speed operation — observe your tool’s max RPM recommendations.

What materials do these blades cut, and how aggressive are they?

Each 20-tooth blade is made from heat- and rust-resistant carbon steel with carbide-like cutting geometry for aggressive, reliable slicing. They are intended to handle thick grasses, brush, small saplings, thorny vines, and light stump work where a typical nylon line struggles.

• Cuts dense weeds, brush, and small woody stems efficiently.
• 20 sharp teeth balance fast material removal with smoother engagement.
• Better maneuverability than large mower decks in confined or rough terrain.
• Not intended for continuous heavy-duty tree felling; use appropriate saws for large trunks.

What maintenance and sharpening options are included?

The kit includes three assorted round files and four washers so you can install, maintain, and lightly sharpen the blades on site. Regular filing preserves tooth geometry and cutting speed while the extra washers help ensure proper mounting and secure fitment.

• Three files sized for tooth re-profiling and edge touch-ups.
• Four washers for correct blade spacing and safe installation.
• Simple field sharpening keeps blades cutting longer between replacements.
• Follow manufacturer torque and safety instructions when tightening blades.

Are these blades safe to use and what precautions should I take?

When fitted and used according to your tool’s guidelines, these carbon-steel blades perform safely for typical trimming tasks. Observe basic safety measures: wear eye and hand protection, clear the work area of bystanders and loose debris, and only operate at recommended RPMs.

• Always disconnect power or stop the engine before mounting or removing blades.
• Use personal protective equipment: gloves, goggles, and long clothing.
• Check blade balance and secure washers/fasteners before each use.
• Inspect teeth for chips; replace if damaged rather than attempting repairs.
