These are CALPALMY 9-inch, 20-tooth carbon-steel chainsaw tooth brush blades sold as a 2-set with files and washers for straight-shaft brush cutters and string trimmers.

Replace worn or inadequate trimmer blades with a heavy-duty, saw-tooth option built for thicker brush and light saplings. The CALPALMY kit includes two round 9" 20T blades engineered from heat- and rust-resistant carbon steel, three round sharpening files sized for .325" chain pitch, and four mounting washers sized to common 1" arbor trimmers. These blades fit many gas and electric straight-shaft machines and are intended for users who need a longer-lasting cutting edge than nylon line or multi-blade discs.

Which machines will these 9" chainsaw tooth blades work with?

These blades are designed for straight-shaft trimmers and brush cutters that accept a 1" arbor and run up to 10,000 RPM. Many popular brands are compatible, but always verify your tool's arbor and maximum RPM before installing a saw-tooth blade to ensure safe operation.

• Fits straight-shaft trimmers with 1" (25.4 mm) arbor diameter
• Suitable for many Husqvarna, Stihl, Ego, Oregon, Hitachi models (check specs)
• Maximum recommended speed: 10,000 RPM — not for high-RPM head-only trimmers

How durable and sharp are the CALPALMY carbon steel blades?

The blades are stamped from fine-grade carbon steel that is heat-treated for added toughness and rust resistance. Their 20-tooth round saw profile offers a balance of aggressive cutting and wear life, generally lasting longer than typical plastic blades or single-sheet discs under similar brush-clearing conditions.

• Heat- and rust-resistant carbon steel construction
• 20-tooth design for efficient chopping of brush and small saplings
• Manufacturing increases lifecycle compared with typical blades

What comes in the kit and how do I maintain the blades?

The kit includes two 9" 20T blades, three round files sized 3/16" for a .325" chain pitch, and four washers (20 mm inner, 25 mm outer diameter). Regular sharpening with the supplied round files and checking for cracks or bent teeth will keep the blades cutting cleanly and safely.

Installation requires basic mechanical skill and attention to torque specs and guard positioning; if you are unsure, consult a qualified technician or your tool's manual.
