Wire cup brush, MILWAUKEE S6 60x13 mm, steel crimped, shank-mounted

The MILWAUKEE S6 wire cup brush, 60 x 13 mm with a shank mounting and steel crimped filaments, is designed for surface preparation and cleaning of metal components. This shank-mounted cup brush is intended for use with compatible handheld grinders and rotary tools and provides aggressive material removal while maintaining filament retention for repeated contact with rust, paint, weld spatter and burrs.

Advantages

The crimped steel filaments combine flexibility and cutting action to remove corrosion, paint and scale from steel surfaces without excessive gouging. The compact 60 x 13 mm cup profile allows access to small or recessed areas while the shank mounting provides fast attachment to rotary tools and small grinders. The construction ensures consistent filament distribution for uniform surface finish and extended brush life under typical metalworking conditions.

Suitable for

• Removing rust and old paint from steel parts
• Cleaning welds and removing slag or spatter
• Deburring cut edges and removing burrs after machining
• Surface preparation before welding, painting or coating

Key specifications

• Brush type: wire cup brush with shank mount
• Filament material: crimped steel wire
• Dimensions: 60 mm diameter × 13 mm cup height
• Mounting: straight shank for direct insertion into rotary tool or small grinder chuck
• Suitable speed range: designed for typical handheld grinder and rotary tool RPMs (check tool limits before use)

How to use

Install the shank in the tool chuck or collet and tighten according to the tool manufacturer’s instructions. Start the tool at low speed to check runout and balance, then increase to the appropriate operating speed within the tool and accessory limits. Hold the brush at a steady angle and apply light to moderate pressure — allow the filaments to do the cutting rather than forcing the brush into the surface. Move the brush across the workpiece in a controlled manner to achieve an even finish and avoid staying in one spot for too long.

Usage recommendations

Use eye protection, gloves and suitable respiratory protection when working with wire brushes. Inspect the brush regularly for worn or damaged filaments and replace the accessory if excessive wear or breakage is visible. Match the brush speed rating to the tool’s maximum RPM and avoid side-loading beyond the brush design to maintain performance and safety.
