Wire cup brush 70 mm M14 Wolfcraft WF2748000 — brass wire

Wolfcraft wire cup brush 70 mm M14 with brass wire filaments is a rotating abrasive accessory designed for surface cleaning and light finishing tasks. With a 70 mm cup diameter and a standard M14 thread, this brush mounts directly to angle grinders and other power tools that accept an M14 arbor. The brass-plated wires provide a balance between material removal and surface protection, making the brush suitable for removing rust, paint, scale and burrs while reducing the risk of scratching softer base metals compared to steel-wire brushes.

Advantages

The brass-wire construction offers effective abrasive action with improved corrosion resistance and reduced aggressiveness on delicate surfaces. The compact 70 mm cup size ensures good accessibility in confined areas and on edges. The M14 threaded attachment provides secure mounting and quick installation on compatible grinders. Designed by Wolfcraft, the brush conforms to common safety and dimensional standards for power-tool accessories and is suitable for repeated light to medium-duty cleaning operations.

Suitable for

• Removing rust and loose paint from metal surfaces
• Deburring welded seams and cut edges
• Surface preparation before priming or painting
• Cleaning metal parts, fittings and hardware
• Light-scale and oxide removal on non-ferrous metals

Key specifications

How to use

Securely fit the M14-threaded brush onto the grinder spindle and tighten according to the tool manufacturer’s instructions. Operate the tool at the recommended speed range for cup brushes and apply light, even pressure; allow the rotating wires to do the work rather than forcing the brush into the surface. Work in smooth passes and keep the brush moving to avoid gouging or uneven abrasion. Wear appropriate personal protective equipment such as safety glasses, gloves and hearing protection when using the brush.

Usage recommendations

Use the brass wire cup brush for light to medium cleaning tasks and on softer base metals to reduce surface marking. Avoid excessive pressure and high-speed use on thin or fragile materials. Inspect the brush regularly for wire loss or damage and replace it if wear compromises performance or safety.
