Wire cup brush AWTools AW55102 for power drills, 65 mm, M14, carbon steel wire

AWTools AW55102 is a 65 mm wire cup brush designed for power drills with an M14 threaded mount. Fitted with crimped carbon steel bristles and a reinforced steel cup, the brush is intended for surface cleaning tasks such as rust and paint removal, deburring and preparing metal surfaces for further finishing. The accessory is compact and lightweight, suitable for use where aggressive material removal is required.

Advantages

The crimped carbon steel wire provides high tensile strength for effective abrasion while the steel powder‑coated cup reinforces the wire fixing for durable operation. The threaded M14 mount fits common 100–125 mm angle grinder thread sizes used on power tools, and the small 65 mm cup size allows access to tighter areas and more controlled cleaning. The brush’s construction balances removal power with manageable weight for handheld drilling tasks.

Suitable for

• Removing rust and loose paint from metal surfaces
• Deburring edges after cutting or machining
• Descaling and surface preparation before welding or painting
• Light to medium cleaning of workpieces and metal components

When it may not be suitable

This wire cup brush is intended for aggressive cleaning on metal and is not suitable for delicate surfaces, plastics, painted finishes you wish to preserve, or fine woodworking. It is also not designed for continuous heavy industrial grinding where larger, specialized brushes or benches are required.

How to use

Fit the brush onto a compatible power drill or angle grinder spindle with the correct M14 thread according to the tool manufacturer’s instructions. Secure the brush firmly before operation.

Wear appropriate personal protective equipment such as eye protection, gloves and a dust mask when removing rust or paint.

What to consider before purchase
