If you search for a CRAFTSMAN brush cutter, you will find three very different things sharing that phrase: an attachment that turns an attachment-capable string trimmer into a brush cutter, a replacement blade for a Craftsman brush cutter you already own, and a set of bristle brushes that has nothing to do with cutting brush at all. The right purchase depends on what you have in the garage right now and what you need to cut.
This guide covers all three and is blunt about which is which. The Expand it 8 in. brush cutter attachment is made by VIYUKI, a third-party brand, and is designed to fit attachment-capable powerheads from many major brands including Craftsman. The Craftsman Residential Grade 8 in. brush cutter blade is a genuine CRAFTSMAN part. The CRAFTSMAN CMMT98312 3-piece bristle brush set is a genuine Craftsman product, but it is a set of cleaning brushes, not a cutter. We compared listings, fit details and part numbers rather than running our own cutting tests.

Best for
Attachment-capable trimmer owners, including Craftsman
Pros
- 8 in 3-tooth TRI-ARC steel blade
- Steel drive shaft, less vibration
- Wrench and handle included
- Fits many attachment-capable powerheads
Cons
- Made by VIYUKI, not Craftsman
- Must match 1 in tube and square shaft
The Expand it 8 in. Brush Cutter attachment is sold under the VIYUKI brand, not CRAFTSMAN. We include it because it is the most practical way to add a brush cutter attachment to a trimmer powerhead that accepts attachments, and the listing names Craftsman among the brands it fits alongside most other major brands.
The cutting head is an 8-inch, 3-tooth TRI-ARC blade made of steel, which the listing says is built to slice through heavy brush. The kit includes the attachment, a wrench and a handle. A steel drive shaft is meant to reduce vibration and extend equipment life, and the listing says it attaches quickly to the power head. For small saplings, woody weeds and dense overgrowth that snap trimmer line, a steel blade like this is the usual answer.
Fit is where you need to be careful. The listing gives specific coupler details: the powerhead coupler accepts a 1-inch aluminum diameter tube, the drive shaft connector is square at .205 inches, and the attachment drive shaft is square at .200 inches across flats. Before you buy, measure your trimmer’s shaft and confirm it is attachment-capable, since fixed-shaft trimmers cannot accept it. This is the pick for Craftsman trimmer owners who want to expand what their powerhead can do, and it gives way to the genuine CRAFTSMAN blade if you already own a dedicated brush cutter.
- 8-inch, 3-tooth TRI-ARC steel blade
- Coupler for 1-inch aluminum tube, square drive shaft
- Steel drive shaft for less vibration
- Includes wrench and handle

Replacing a worn Craftsman brush blade
Pros
- Genuine CRAFTSMAN residential blade
- Lists part numbers 791-145873B, 49M5873P953
- No assembly required
Cons
- Title says 8 in, width listed 6.75 in
- Not an attachment, blade only
The Craftsman Residential Grade 8 in. L Brush Cutter Blade is the only genuine CRAFTSMAN cutting product in this roundup. It is a replacement blade, not an attachment, and the listing states it is not attachment capable. The manufacturer is listed as MTD Products, with the CRAFTSMAN part number CMXGZAM105031.
Compatibility is given by part number: 791-145873B and 49M5873P953. If your existing Craftsman brush cutter blade carries one of those numbers, this is the direct replacement. The description lists a residential grade, a length of 8 inches, a 4-point shape, no assembly required and one blade per pack. One detail to note: the description also lists a width of 6.75 inches, while the title says 8 in. The listing does not explain the difference, so match by part number rather than size alone.
This Craftsman 8 inch brush cutter blade suits anyone keeping an existing brush cutter in service. A dull or chipped blade tears rather than cuts, which strains the engine and leaves ragged stems, so swapping it is one of the simplest maintenance jobs you can do. Keep a Craftsman 1/2 socket set handy for the retaining nut, and always disconnect the spark plug or battery before touching the blade.
- Genuine CRAFTSMAN, residential grade
- Compatible with 791-145873B and 49M5873P953
- 4-point blade, no assembly required
- 11.2 ounces

The CRAFTSMAN CMMT98312 CRFT 3PC Bristle Brush Set is a genuine Craftsman product, but it is not a brush cutter. It shows up in brush cutter searches because of the word “brush”. What you get is three hand brushes: one brass, one stainless steel and one nylon, in red.
The listing says the different bristle materials suit different materials and jobs, and that the compact design reaches confined areas and corners. In practice, that makes the Craftsman bristle brush set a useful companion for any brush cutter owner: stainless or brass bristles can scrub dried sap and grass off a blade and guard, while nylon is gentler for plastic housings and air intake areas. The listing gives few other details beyond dimensions of 10.9 x 5.1 inches.
Buy it if you want to keep blades, trimmer heads and other tools clean, not if you need to cut vegetation. For a cordless tool to pair with it at the bench, see our look at the Craftsman brushless impact driver.
- Brass, stainless steel and nylon brushes
- Compact for corners and tight spots
- Not a cutting tool

NOTES
Buying Tips for CRAFTSMAN Brush Cutters
Start with what you own. If you have an attachment-capable trimmer, a brush cutter attachment adds a steel blade to the same powerhead. If you have a dedicated brush cutter, you need a replacement blade that matches your part number. If you have neither, a bristle brush set will not help with brush clearing.
Check fit by specification, not by name. The VIYUKI attachment lists precise tube diameter and drive shaft dimensions, and the CRAFTSMAN blade lists exact part numbers. Measuring your shaft and reading the number stamped on your old blade takes a few minutes and avoids a return.
Match the tool to the vegetation. Trimmer line handles grass and soft weeds, but it wears quickly against woody stems, blackberry canes and thin saplings. That is the point where a steel blade pays off, whether as an attachment on a trimmer powerhead or as a fresh blade on a dedicated brush cutter. For light edging along a path, you may not need a blade at all.
Finally, respect a steel blade. Brush cutter blades throw debris and can kick back when they hit a stump or rock. Wear eye protection, long pants and boots, keep bystanders well away, and clean and inspect the blade after each session, which is where a stiff bristle brush earns its place.
