Heavy-Removal Grinding Wheels for Angle Grinders—Use on Nonmetals

Image of Product. Front orientation. Contains MultipleImages. Grinding Wheels. Heavy-Removal Grinding Wheels for Angle Grinders—Use on Nonmetals.

Wheels have a large surface area and a thick layer of rough abrasive for heavy material removal on concrete and stone. They are also known as Type 11 wheels, flared-cup wheels, snagging wheels, and cup stones.

Wheels are silicon carbide, which won't generate much heat.

Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

Full Backing—The full backing provides additional support.

Dust Hoods for Angle Grinders

Connect these dust hoods to your vacuum system to contain and remove dust and fine particles while grinding or cutting. They fit all major brands of angle grinders, including DeWalt, Milwaukee, and Makita. These dust hoods are OSHA compliant for point-of-origin dust containment. To attach these dust hoods to a standard 2" dia. vacuum hose, they either include an adapter hose or you can add a vacuum adapter (sold separately).

ABS	Nylon

ABS—ABS dust hoods are disposable, so they’re good for quick jobs. Cut away the front edge of the hood to grind close to a wall or an edge. They don’t come with an adapter hose.

Nylon—Nylon dust hoods contain glass filler, so they’re durable and resist abrasion. They have a sliding front edge for grinding close to a wall or an edge.

Multipurpose Grinding Wheels for Angle Grinders

Grind a variety of materials, such as metal, fiberglass, and ceramics. These grinding wheels work with aluminum when properly lubricated. The diamond abrasive is core bonded to expose more abrasive particles, so they’ll last longer and outperform traditional grinding wheels with fewer sparks and less odor. Also known as (AVOS) Type 29 wheels, they have an upside-down dish shape for a large contact area.

Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

Portable Vertical Grinders for Wheels


For Straight-Cup Grinding Wheel	For Flared Cup Grinding Wheel	For Raised Hub Grinding Wheel

With more power than angle grinders, these vertical grinders quickly remove large amounts of stock, rust, scale, and other materials. They’re also heavier than angle grinders, so they reduce fatigue when working on a bench. They’re good for heavy duty applications in foundries and shipyards. The threaded spindles accept grinding wheels. These grinders have a lever lock to prevent accidental start-up.

Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

Warning: Use wheels that have a greater rpm rating than the no-load rpm of your tool.

Type 27 Grinding Wheel—Type 27 cutoff wheels outperform Type 1 wheels when making flush cuts. Also known as raised-hub and depressed-center cutoff wheels.

Medium Duty Air-Powered Angle Grinders for Grinding Wheels and Sanding Discs

More durable than our Light Duty Grinders, these are built for frequent weld grinding, surface preparation, and deburring.

The angled head accesses hard-to-reach places. A threaded spindle allows quick, secure accessory changes without additional tools. A lever lock prevents accidental start-up, reducing injury risk during accessory changes and between tasks. Variable-speed control lets you match rpm to the accessory and material. This improves finish quality and extends accessory life.

Caution: Use only accessories rated for a higher rpm than the maximum speed of the grinder you choose.

Multipurpose Angle Grinder Cutoff Wheels


	Side View

Ideal when working across multiple materials, these wheels are specially constructed to cut plastic, fiberglass, concrete, and ceramic, as well as metal. They also work with sheet metal. They contain less than 0.1% iron, chloride, and sulfur contaminants to prevent corroding and discoloring stainless steel and other nickel-alloyed steel.

Warning: Use wheels that have a greater rpm rating than the no-load rpm of your tool.

Cordless Angle Grinders for Grinding Wheels and Sanding Discs

With no cord to limit mobility, you can take these battery-powered grinders wherever they’re needed. Download the app to track their location, customize settings, view usage data, and receive alerts before they need repair.

The included type 27 wheel guards are required when using grinding wheels and cups. Backup pads (not included) are required when using sanding discs. Thread the backup pad onto the tool's arbor, then attach a sanding disc and secure with its disc nut.

Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

Milwaukee—Milwaukee grinders have a spindle lock for fast wheel changes.
