Bosch Professional Grinder Cup Brushes at Tooled-Up.com

Bosch Professional Grinder Cup Brushes are wire brush accessories for angle grinders, used for rust removal, weld cleaning, paint stripping and surface preparation on metal. Tooled-Up.com stocks them in crimped and knotted wire styles, with steel, stainless steel (Inox) and brass-coated wire options, so the brush can be matched to the material and the job.

The selection covers standard threaded brushes such as the Bosch PRO 0.5mm Knotted Steel Wire Cup Brush and the Bosch PRO 0.3mm Crimped Brass Coated Wire Cup Brush. It also includes the Bosch PRO X-LOCK versions, which fit X-LOCK angle grinders without a spanner.

Wire diameters run from 0.3mm to 0.8mm, so you can choose between controlled, lighter cleaning and heavy-duty material removal.

Key Features of Bosch Professional Grinder Cup Brushes

• Knotted wire construction: twisted bundles of wire give an aggressive action, which clears welded seams, heavy rust, old paint, varnish and underseal quickly.
• Crimped wire construction: a more flexible brush for general cleaning and lighter rust removal, with less risk of gouging softer or thinner surfaces.
• Inox stainless steel wire: suited to stainless steel and non-ferrous surfaces, so you avoid transferring ferrous particles that can lead to corrosion.
• Brass-coated wire: a gentler option for cleaning where a less aggressive finish is needed.
• Range of wire thicknesses: 0.3mm, 0.35mm, 0.5mm and 0.8mm wires let you balance finish quality against speed of removal. Thicker wire is tougher, while finer wire gives more control.
• X-LOCK fitting: tool-free changes on compatible grinders save time when you swap between brushes and discs during a job.

Frequently Asked Questions

What is the difference between knotted and crimped cup brushes?

Knotted brushes have wires twisted into bundles for aggressive removal of heavy rust, scale and coatings. Crimped brushes have a more flexible wire for general cleaning and lighter work.

Which Bosch Professional cup brush should I use on stainless steel?

Choose an Inox or stainless steel wire brush, such as the Bosch PRO 0.3mm Inox Crimped or the 0.35mm Inox Knotted. Standard steel wire can leave ferrous particles that cause rust spots on stainless surfaces.

What does X-LOCK mean on a cup brush?

X-LOCK brushes fit compatible X-LOCK angle grinders without a spanner, which makes changing accessories quicker. Check that your grinder supports X-LOCK before buying, as these brushes are not for standard threaded spindles.

How do I use a cup brush safely?

Always wear eye or face protection, gloves and hearing protection, and never exceed the maximum speed marked on the brush. Check for loose or damaged wires before each use, and follow HSE guidance. If you are removing old coatings, COSHH requirements may apply.
