3 Pack 9 in 20T Chainsaw Tooth Brush Blades - Heavy Duty Brush Cutter

In this review of the 3 Pack 9 in 20T Chainsaw Tooth Brush Blades from Dunhil, the bottom line is simple: this kit is for homeowners and landscapers who need a rugged, carbon steel blade set for tackling thick weeds, woody grasses and small tree saplings. The single biggest reason to buy is the kit's practical combination of three 9 in, 20-tooth blades plus files and washers, which delivers a straightforward replacement option when a trimmer's nylon line is not enough. Installation is quick on trimmers with a 1 in arbor and the blades are built for repeated cutting under demanding conditions.

Key Features

• Diameter and tooth count: The 9 in blade with 20 teeth provides aggressive cutting for dense brush and tall grass.
• Material: Carbon steel construction keeps the blade sharper and more durable under impact and wear when clearing woody vegetation.
• High speed rating: Rated up to 10,000 RPM so it will perform on high-revving brush cutters when used with proper guards and PPE.
• Complete kit: Includes three blades plus four round files and four washers so users can sharpen and mount blades without hunting parts.
• Easy fit: Designed for trimmers with a 1 in arbor, allowing quick swap from nylon head to metal blade for tougher jobs.

Who It's For

This kit suits backyard owners, property managers and light commercial landscapers who need a dependable metal cutting option to remove thick weeds, shrubs and small trees that nylon line struggles with. It is especially useful for jobs where repeated cutting through woody stems is required rather than one-off trimming.

Those who should look elsewhere include users of trimmers with nonstandard arbors or incompatible models (some users reported fit issues with certain brands), and gardeners who only trim turf or delicate ornamental plants, where a nylon line head remains the safer, cleaner choice.

Pros & Cons

Pros

• Carbon steel blades stay sharp and resist wear for demanding brush clearing.
• Kit includes files and washers, making maintenance and installation convenient.
• 20-tooth, 9 in diameter cuts woody grasses and small trees effectively when used correctly.
• Clear instructions to match blade rotation simplify setup on compatible 1 in arbor trimmers.

Cons

• Fit can be mixed on some trimmer brands, so compatibility should be confirmed before purchase.
• Metal blades require strict use of leg and eye protection and are overkill for light lawn edging.

Specifications

For heavy brush clearing on compatible trimmers, this kit is a practical, cost-effective choice.
