An angle grinder is one of the most versatile tools in any workshop, but the real magic lies in the attachments you choose. Whether you’re cutting rebar, carving wood, or smoothing concrete, the right disc or wheel transforms your grinder into a specialised machine. To get the most out of these attachments, you need a reliable angle grinder that delivers consistent power and control.
We’ve tested and reviewed some of the top-rated grinders on the market. Models like the DEWALT DWE402 and the Bosch GWS8-45 offer the performance required for heavy-duty work. Below, we break down the best attachments for metal, wood, and masonry, and recommend a grinder to match each task.
Metalworking Attachments: Cutting, Grinding, and Finishing
Metal is the most common material for angle grinder work. For cutting, thin metal cutting discs (1/16 inch) provide clean, fast cuts with minimal burrs. Grinding wheels (4.5 inch) remove material quickly for weld smoothing or edge preparation. For a finer finish, flap discs combine grinding and polishing in one step.
The DEWALT DWE402 (4.5-inch, 11-amp, 11,000 rpm) handles metalwork effortlessly. Its ergonomic paddle switch and compact design reduce fatigue during prolonged use. For lighter jobs, the Bosch GWS8-45 is a budget-friendly choice that still offers 6.0 amps of reliable power.
Recommended attachments for metal:
- Cut-off wheels – for thin metal, rebar, and sheet metal
- Grinding wheels – for weld seams and rust removal
- Flap discs – for blending and finishing surfaces
Woodworking Attachments: Carving, Sanding, and Shaping
Angle grinders aren’t just for metal. With the right attachments, they become powerful woodworking tools. Lancelot chainsaw wheels carve intricate shapes and remove material rapidly. Sandpaper flap wheels and backing pads with sanding discs let you smooth curved surfaces or remove paint. For detail work, carbide burrs shape edges and recesses.
The DEWALT DWE4011 (4.5-inch, 7.0 amp) features a one-touch guard adjustment that saves time when switching between wood and metal attachments. It’s also lighter than many competitors, making it ideal for overhead sanding.
Best wood attachments:
- Chain carving wheel – for aggressive shaping and sculpting
- Sanding flap wheel – for stripping paint and smoothing contours
- Carbide grinding disc – for removing wood fast without clogging
Masonry Attachments: Cutting Brick, Stone, and Concrete
For masonry work, diamond blades are the go-to attachment. Segmented blades cut brick and block cleanly, while continuous rim blades produce chip-free cuts in tile. Cup wheels (diamond or silicon carbide) grind down mortar joints and smooth concrete surfaces. For heavy-duty removal, a diamond tuckpointing wheel is essential.
The DEWALT 20V MAX DCG413B (cordless, 4.5-inch, brushless) offers the mobility and power needed for jobsite masonry work. Its kickback brake and paddle switch provide extra safety when cutting stone.
Top masonry attachments:
- Diamond segmented blade – for fast cutting of concrete, brick, and stone
- Diamond continuous rim blade – for tile and porcelain
- Cup wheel (diamond) – for grinding concrete and removing thinset

Safety and Accessories for Better Results
No matter which attachment you use, safety comes first. Always wear eye protection, gloves, and a dust mask when cutting or grinding. A guard specific to the attachment type (e.g., cutting guard vs. grinding guard) prevents debris from flying back toward you. For added control, use a side handle for two-handed operation.
Investing in quality accessories also extends the life of your grinder.

For wood, a chainsaw carving wheel on the Bosch GWS8-45 gives you unmatched shaping ability. For masonry, a diamond blade on the cordless DEWALT DCG413B delivers portability and power.
