Bent cup brush Polax M14 115 mm, braided steel wire bristles

Bent cup brush Polax M14 115 mm with braided steel wire bristles is a wire-wheel accessory designed for use on angle grinders and compatible bench tools. The 115 mm diameter and braided-wire construction provide concentrated contact and high abrasion for effective removal of rust, paint, scale and welding slag while preparing metal surfaces for finishing. The M14 threaded arbor enables secure mounting on grinders with matching spindle threads, and the bent cup profile helps reach edges and contours while maintaining stable operation during aggressive cleaning tasks.

Advantages

The braided steel wire bristles deliver high durability and consistent abrasive action, allowing extended service life under heavy workloads. The cup shape concentrates the brush surface for controlled material removal and improved access to grooves and weld seams. The M14 thread ensures firm attachment to standard angle grinders, reducing wobble and vibration. Overall, the brush balances aggressive cleaning performance with stable rotation for efficient metal surface preparation.

Suitable for

• Rust and scale removal from steel and iron surfaces
• Paint and coating stripping on metal parts
• Deburring and edge blending after cutting or welding
• Cleaning weld seams and removing slag
• Surface preparation before painting, plating, or priming

How to use

Select a grinder with an M14 spindle and ensure the machine is unplugged or its battery removed before fitting the brush. Secure the brush onto the spindle according to the tool manufacturer's instructions, confirm tight mounting and that the cup face is free from damage or obstruction. Operate the grinder at the recommended speed range for wire brushes, applying moderate pressure and consistent motion across the workpiece. Keep the brush angle and movement steady to avoid digging in; allow the wire bristles to do the cutting rather than forcing the tool. After use, inspect the brush for excessive wear or loose wires and replace when performance declines or safety is compromised.

Usage recommendations

Wear appropriate personal protective equipment including eye protection, gloves, and hearing protection. Use a grinder guard and maintain a steady speed; avoid side-loading the cup brush. For painted or coated surfaces, test on a small area to verify finish results. Store the brush in a dry place to prevent corrosion of the wire bristles.
