Tyrolit Cup Brushes | Wire Cup Brushes for Angle Grinders & Surface Prep
Tyrolit Cup Brushes are heavy-duty, power-driven wire brushes shaped like a cup, designed to be mounted on angle grinders and stationary machines for aggressive cleaning of large, flat, or contoured metal surfaces. The cup shape exposes a wide annular ring of wire tips, maximizing the contact area and allowing the operator to clean steel plates, remove heavy mill scale, strip thick coatings, and prepare weld seams efficiently. Tyrolit produces knotted wire cup brushes for maximum aggression on heavy corrosion and slag, and crimped wire cup brushes for medium-duty cleaning where a finer surface texture is required. The brushes are manufactured using oil-tempered high-carbon steel wire for general steel, and INOX stainless steel wire for aluminium, stainless steel, and non-ferrous applications to prevent cross-contamination. A key design feature is the threaded nut (M14, 5/8"-11 UNC) moulded directly into the brush body, allowing secure attachment to angle grinders without the need for an adapter. The speed rating of every Tyrolit cup brush is clearly marked and tested, ensuring operators can work safely at the high RPM of modern angle grinders. In shipyards, structural steel shops, and heavy fabrication sites, Tyrolit cup brushes are the go-to tool for rapid, uniform surface preparation prior to welding or coating.

Trusted by Industry Leaders
Wide-Face Brushing for Fast Coverage
The cup design provides a broad ring of wire tips, cleaning large flat surfaces such as steel plates and decks rapidly and uniformly, significantly reducing labor time.
Knotted Wire for Extreme Aggression
Twisted wire knots concentrated in a cup provide maximum impact force, easily removing thick rust scale, burnt-on coating, and heavy weld spatter in a single pass.
Crimped Wire for Textured Finishes
Straight, crimped wire cups deliver a finer, more flexible brushing action that is excellent for deburring, light corrosion removal, and creating a paintable anchor profile without gouging.
INOX Stainless Steel Brushes for Contamination-Free Work
Tyrolit INOX cup brushes are iron-free, preventing the rust bloom and pitting corrosion that can occur when fabricating stainless steel tanks, railings, and food-processing equipment.
Direct-Thread Mounting for Security
The integrated M14 or 5/8"-11 UNC thread allows the brush to be spun directly onto the angle grinder spindle, eliminating the wobble and loosening seen with adapter-mounted brushes.
Verified High-Speed Safety
Every Tyrolit cup brush is speed-tested and clearly labelled with its maximum safe RPM, giving operators confidence when using brushes on high-speed grinders exceeding 10,000 RPM.
Why Tyrolit Cup Brushes Are the Professional's Choice for Surface Preparation
Cheap cup brushes shed wires quickly, become unbalanced, and can fail catastrophically at high speed. Tyrolit combats this through proprietary wire-knotting and bonding processes. The wires are pre-tensioned and tightly knotted, then encapsulated in a high-strength polymer ring, which gives the brush structural integrity even as the wire tips wear down. This prevents the "bird's nest" effect of loose wire that can stall an angle grinder or injure the operator. For industrial contractors, the longevity of Tyrolit cup brushes is a direct cost saving; one brush does the work of several unbranded alternatives, and there is less downtime spent changing consumables. The availability of INOX brushes also means a single supplier can service all steel and stainless steel requirements, simplifying procurement and storeroom inventory.
Selecting the Right Tyrolit Cup Brush for Your Material and Finish
Material and desired profile dictate the choice. For carbon steel that will be painted, a crimped carbon steel cup brush leaves an ideal anchor profile. For stainless steel that must remain corrosion-resistant, the Tyrolit INOX crimped cup brush is essential. For removal of heavy epoxy or bitumen before welding, a knotted carbon steel cup brush provides the fastest stripping. The diameter (typically 65 mm to 125 mm) must match the grinder guard capacity. Tyrolit provides clear color-coded badging on the brush and pack to prevent accidental use of the wrong wire type, a critical safety and quality control in fabrication shops.
