Air-Powered Wire Bristle Blasters


Shown in Use

Connect these blasters to an air source to remove contaminants from metal surfaces without the mess of abrasive media. They strip corrosion, coatings, mill scale, and other contaminants without removing underlying surface material. A rotating belt of wire bristles snaps against the surface to mimic the impact of blasting media. The impact of the bristles creates the same textured finish as blasting media for coating and sealant adhesion. Because they don’t use abrasive media, the only leftover material is the removed debris. This reduces cleanup time and keeps the surrounding air cleaner.

Since they clean only what they touch, these blasters work more slowly than abrasive blasters that sweep large areas. Use them for small- to medium-sized tasks such as cleaning weld seams and prepping parts for coatings.

Hazardous Location Rating—These blasters are approved for use in locations where ignitable gases may be present, such as chemical plants and refineries.

Belts

These belts last for around one hour of blasting.

Steel Bristles—Harder than stainless steel bristles, these belts clean your surface faster and more aggressively. Use them to clean ferrous metals such as steel.

Stainless Steel Bristles—Prevent contaminating your surface with iron. Use these belts to clean non-ferrous metals such as aluminum and stainless steel.

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.

Electric Wire Bristle Blasters


Shown in Use

Strip contaminants from metal surfaces without the mess of abrasive media. These blasters remove corrosion, coatings, and mill scale without removing underlying material. A rotating belt of wire bristles snaps against the surface to mimic the impact of blasting media. The impact of the bristles creates the same textured finish as blasting media for coating and sealant adhesion. Because they don’t use abrasive media, the only leftover material is the removed debris. This reduces cleanup time and keeps the surrounding air cleaner.

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.

Cordless Wire Bristle Blasters


Shown in Use

No need for blasting media, power outlets, or compressed air. These blasters clean and texture surfaces wherever they’re needed. They strip corrosion, coatings, mill scale, and other contaminants from metal surfaces without removing underlying surface material. A rotating belt of wire bristles snaps against the surface to mimic the impact of blasting media. The impact of the bristles creates the same textured finish as blasting media for coating and sealant adhesion. However, they spin slower than electric and air-powered blasters, so they can’t remove heavy coatings and rust. Because they don’t use abrasive media, the only leftover material is the removed debris. This reduces cleanup time and keeps the surrounding air cleaner.

Wire Bristle Blaster Belts

Shown in Use

Strip corrosion, coatings, mill scale, and other contaminants without the mess of abrasive media. Pair these belts with a wire bristle blaster to rotate them at high speeds. As they rotate, wire bristles strike a metal bar on the blaster, bend back, and snap forward onto your work surface to mimic the impact of blasting media. The impact of the bristles removes material and creates a textured finish for better coating and sealant adhesion.
