VIDICA 2 Pack Carbon Steel Brush Cutter Blades, 10" x 3 Teeth Weed Eater Blades for 20mm or 25.4mm Arbor, Compatible with Husqvarna, Stihl, Ego, Oregon, Hitachi, Makita Brush Cutter, Weed Wacker etc

What It Is

This is a set of two carbon steel brush cutter blades designed for heavy-duty vegetation clearing. Each blade measures 10 inches in diameter with 3 teeth, intended for use on string trimmers converted to metal blades for cutting thick weeds, brush, and small saplings.

Fitment & Compatibility

Before buying, confirm two critical measurements:

• Arbor size: These blades fit 20mm or 25.4mm center holes. Check your trimmer’s arbor diameter—most Stihl and Husqvarna models use 25.4mm, while many Makita and EGO units use 20mm. A bushing adapter may be needed if your arbor is smaller.
• Blade thickness: 0.047 inches (1.2mm). Ensure your trimmer’s blade retainer and nut can secure this thickness without bottoming out.

This blade is aftermarket, not OEM. It claims compatibility with Husqvarna, Stihl, EGO, Oregon, Hitachi, Makita brush cutters, but only if your unit supports a metal blade. Check your owner’s manual for “brush cutter” or “blade” approval—using a metal blade on a string trimmer not rated for it voids warranty and is unsafe.

Key Things to Know

• Material: Carbon steel is durable but rusts quickly. Wipe dry after use and store in a dry place.
• Installation difficulty: Moderate. You’ll need a lockup tool or wrench to remove the trimmer head and a correctly torqued nut (typically 25-35 ft-lbs). Reverse-thread nuts are common—verify direction.
• Common gotcha: These blades require a blade guard (sold separately on many trimmers) and a straight shaft. Curved-shaft trimmers usually cannot accept metal blades due to gearbox limitations.
• Performance: 3 teeth cut aggressively but can bog in thick grass. Best for woody stems, not fine trimming.

Should You Buy It

Buy these if you need budget-friendly, multi-brand compatible blades for occasional heavy brush clearing on a straight-shaft trimmer that supports metal blades. Skip if you need rust-resistant stainless steel, or if your trimmer is curved-shaft or not rated for blades—you risk equipment damage or injury. For light grass, a standard string head is safer and easier.
