ATIE 10" 3-Tooth Carbon Steel Brush Cutter Blades — 10in x 3mm, Fits 20mm/25.4mm Arbor, Heavy-Duty Cutting

ATIE 10" x 3T heavy-duty carbon steel brush cutter blades are rugged three-tooth replacement blades designed to clear thick weeds, brushwood, and dense undergrowth on 20mm or 25.4mm arbors.

These 10-inch, 3.0 mm thick blades are engineered for homeowners and pros who need reliable cutting power from a string trimmer or brush cutter. Machined from carbon steel, each blade delivers solid impact resistance and edge retention for cutting tough vegetation. The kit includes washers that let the blade mount to either a 20 mm or 25.4 mm arbor, making them compatible with many popular trimmer brands such as Husqvarna, Stihl, and Echo.

What kind of vegetation can these blades handle?

These three-tooth blades are made to tackle heavy weeds, brushwood, dense grass and small saplings that nylon line struggles with. They work well where thicker stems and tangled undergrowth are common.

• Clears thick weeds and long grass quickly
• Cuts through brushwood and thorny bushes
• Handles light saplings and woody stalks

How do I fit the ATIE 10" blade to my trimmer?

The blades come with washers that adapt the center hole to either a 20 mm or a 25.4 mm arbor. Fitment requires removing the trimmer head, positioning the washer and blade, and securely tightening the flange per your tool’s instructions.

• Includes washers for 20 mm and 25.4 mm arbors
• Compatible with many mower/trimmer models (Husqvarna, Stihl, Echo)
• Follow your tool’s torque and safety steps when installing

How should I maintain and sharpen these carbon steel blades?

Maintenance is straightforward: keep the blades clean of sap and debris, inspect for damage, and use a flat file to restore the edge as needed. Replace blades when cracks, deep nicks, or significant wear appear to maintain safe cutting performance.

• Wipe off debris after each use to prevent corrosion
• Sharpen with a flat file along original bevels
• Replace blades if bent, cracked, or excessively worn

Are these blades safe to use — what precautions are recommended?

When installed and used correctly, these blades are an effective cutting solution; however, they require the same safety precautions as other metal cutting blades. Always follow manufacturer guidelines for your brush cutter and wear appropriate protective gear.

• Wear eye, ear, and lower-body protection
• Confirm secure mounting and correct rotation direction
• Clear the work area of bystanders and loose debris
