Bosch Professional Rotary Cup Brushes

Bosch Professional Rotary Cup Brushes at Tooled-Up.com

Bosch Professional Rotary Cup Brushes are power tool accessories for fast surface preparation and cleaning. Fitted to an angle grinder, the cup shape puts the filaments in contact with large flat surfaces, so you can strip coatings and clean metal quickly without hand scrubbing.

The Bosch Professional selection is split into two types: Wire Cup Brushes for aggressive cleaning and Nylon Cup Brushes for more controlled finishing. Between them they cover heavy rust removal and gentler work on surfaces that need protecting.

Tooled-Up.com stocks Bosch Professional Rotary Cup Brushes for tradespeople and serious DIYers who want dependable accessories to match their Bosch Professional grinders and other power tools.

Key Features of Bosch Professional Rotary Cup Brushes

• Cup brush shape: The wide, flat brushing face covers more surface per pass than a wheel brush, which suits large panels, plate and weld runs.
• Wire filament options: Wire Cup Brushes give an aggressive cutting action for rust, scale, old paint and weld residue.
• Nylon filament options: Nylon Cup Brushes are the gentler choice for finishing and light cleaning, where you want to avoid removing too much material.
• Grinder-ready fitting: Cup brushes for angle grinders are made to thread onto the spindle. M14 is a common size, so check the thread on the product listing against your tool.
• Rated maximum speed: Each brush has a maximum operating speed. Always make sure it exceeds your grinder's no-load speed.

Popular Bosch Professional Rotary Cup Brushes

Wire Cup Brushes

Wire Cup Brushes are the first choice for demanding jobs. Use them to remove heavy rust, flaking paint, scale and slag from steel and other robust metal surfaces. Browse the Bosch Professional Wire Cup Brushes at Tooled-Up.com to find the right fitting for your grinder.

Nylon Cup Brushes

Nylon Cup Brushes give a more forgiving finish. They suit lighter cleaning and surface refinishing, and work on materials where a steel wire brush could scratch or remove too much. They are a sensible option when you want to clean up a surface without changing its profile.

Frequently Asked Questions

Should I choose a wire or nylon cup brush?

Choose a wire cup brush for heavy-duty rust, paint and weld cleaning on tough metal. Choose a nylon cup brush for lighter cleaning and finishing where you want a gentler action.

Can I use a Bosch Professional cup brush on an angle grinder?

Yes, provided the brush is designed for angle grinders and its thread matches your tool's spindle. Check that the brush's maximum rated speed is higher than your grinder's no-load speed, and keep the guard fitted where the tool allows.

What safety equipment do I need?

Wear eye or face protection, gloves and hearing protection, as wire brushes can throw off fragments and sparks. Follow HSE guidance, and where you are removing old coatings that may contain hazardous substances, work in line with COSHH requirements.

When should I replace a cup brush?

Replace it when filaments are badly worn or missing, the cup is damaged or distorted, or cleaning performance drops noticeably. Check the brush before each use and let the tool reach full speed before it touches the workpiece.
