Wire cup brush Polax Koniskā birste M14 100mm, braided steel bristles

Polax conical wire cup brush M14 100mm with braided steel bristles is designed for aggressive surface treatment on metal. The conical shape concentrates bristle contact for targeted cleaning and deburring while the M14 thread makes it compatible with angle grinders and rotary tools that accept M14 accessories. This accessory is intended for removing rust, paint and scale, preparing welds and metal surfaces for finishing, and restoring metal parts where robust abrasion is required.

Advantages

The braided steel bristles provide increased stiffness and wear resistance compared with loose-wire brushes, ensuring a stable working profile and longer life under heavy use. The conical geometry allows better access to corners and internal contours than flat cup brushes and delivers focused material removal. The M14 threaded mounting secures the brush to standard European angle grinders for safe, high-speed operation.

Suitable for

• Removing rust and scale from steel structures and parts
• Stripping old paint and coatings from metal surfaces
• Surface preparation before welding, painting or galvanizing
• Deburring and chamfering edges on castings and machined components
• Cleaning weld seams and preparing joints

Key specifications

• Brush shape: conical (tapered) cup
• Thread type: M14 standard thread for angle grinders
• Diameter: 100 mm
• Bristle material: braided steel wire for high abrasion resistance
• Intended rotation direction: radial for surface contact and edge access
• Typical application speeds: suitable for medium to high-speed angle grinders (refer to tool limits)

How to use

Securely mount the conical wire cup brush onto an angle grinder with an M14 spindle, ensuring the tool is unplugged or its battery removed before fitting. Tighten according to the grinder manufacturer's instructions and check that the brush spins freely without wobble. Operate the grinder at the recommended speed range for the brush and apply steady, moderate pressure; avoid forcing the brush to prevent premature wear or wire breakage. Move the rotating brush across the workpiece in smooth passes, keeping the brush angle consistent to achieve even material removal.

Usage recommendations

Wear appropriate personal protective equipment: eye and face protection, gloves, long sleeves and hearing protection. Inspect the brush before each use and do not use if wires are missing or the structure is damaged. Match brush size and speed with the tool's maximum RPM and avoid side-loading beyond the brush design limits. For painted surfaces, test on a small area to ensure desired removal rate and to avoid substrate damage.
