Brush AWTools front-mounted 100 mm M14 knotted wire AW40545

AWTools front-mounted 100 mm M14 knotted wire brush AW40545 is a workshop-grade accessory designed for angle grinders. The brush has a 100 mm working diameter and a standard M14 thread to fit most handheld grinders. Knotted steel wire filaments are formed into dense tufts for aggressive material removal, effective rust and paint stripping, and cleaning of welded seams and metal surfaces. The construction is suitable for heavy-duty preparation and surface conditioning in construction, fabrication, and maintenance tasks.

Advantages

The knotted wire design provides concentrated mechanical action for fast removal of scale, corrosion, and old coatings while resisting filament deformation during use. The compact 100 mm diameter offers good control and visibility when working in tight spaces or on edges. The M14 threaded arbor ensures secure mounting to compatible angle grinders for stable operation. The steel wire filaments deliver consistent abrasion on metal substrates, reducing preparation time before welding, painting, or applying protective coatings.

Suitable for

• Removing rust and scale from steel and iron surfaces
• Stripping paint and old coatings from metal
• Cleaning weld seams and preparation for re-welding
• Surface conditioning before priming and painting
• Light deburring and edge cleaning in workshops

Key specifications

• Working diameter: 100 mm
• Thread type: M14 (for angle grinders)
• Filament type: knotted steel wire
• Brush style: front-mounted/ cup with knotted tufts
• Typical applications: heavy-duty surface preparation, rust and paint removal

How to use

Mount the brush on an angle grinder with an M14 spindle, ensuring the tool is disconnected from power before fitting. Tighten securely according to the grinder manufacturer’s instructions. Operate the grinder at the recommended speed range and apply moderate, consistent pressure while keeping the brush moving to avoid gouging the substrate. Use controlled passes to remove rust or paint, and periodically inspect the brush for wear or damaged filaments. Replace the brush when performance decreases or wires become excessively worn or broken.

Usage recommendations

Use appropriate personal protective equipment including eye protection, gloves, long sleeves, and hearing protection. Avoid excessive pressure and follow the angle grinder’s speed limits; do not use the brush on soft materials where aggressive wire filaments may cause damage. Store in a dry place to prevent premature corrosion of the steel filaments.
