Aptel wire cup brush M14 100x10 mm stainless steel crimped 0.35 mm for angle grinders

The Aptel wire cup brush M14 100x10 mm with 0.35 mm crimped stainless steel filaments is a rotary surface-preparation accessory for angle grinders. Designed for mechanical removal of rust, paint, scale and for deburring and edge blending on ferrous and some non-ferrous metals, this cup brush mounts on grinders with an M14 arbor thread. Corrosion‑resistant stainless steel bristles maintain performance in damp or corrosive workshop environments and extend usable life compared with plain carbon wire brushes.

Advantages

This cup brush combines a compact 100×10 mm cup profile with crimped 0.35 mm stainless steel filaments to provide controlled aggressiveness and good surface coverage. The M14 mounting thread gives straightforward compatibility with standard angle grinders, while the stainless steel construction reduces oxidation and contamination risk when working on stainless or coated parts. The crimped wire layout improves material removal while helping to avoid excessive gouging on metal surfaces.

Suitable for

• Removing rust, scale and old paint from metal surfaces
• Deburring and edge rounding after cutting or welding
• Surface preparation prior to welding, priming or painting
• Cleaning stainless steel and corrosion‑sensitive components
• General workshop and industrial metal maintenance tasks

When it may not be suitable

This wire cup brush is intended for use on metal and is not suitable for wood, plastics or soft non‑metal materials where the stainless steel filaments could cause gouging or splintering. It is not designed for fine finishing or polishing where a non‑abrasive or very fine grit product is required. Do not use at speeds above the grinder or brush maximum rated RPM.

Key specifications

• Cup diameter: 100 mm
• Cup height/profile: 10 mm
• Filament material: stainless steel
• Filament type: crimped
• Filament diameter: 0.35 mm
• Mounting thread: M14
• Intended tool: angle grinder

How to use

Fit the cup brush onto an angle grinder with an M14 arbor thread and ensure the spindle lock and wrench are used according to the grinder manufacturer's instructions. Securely tighten the brush and check that it spins freely before applying power. Operate the grinder at the recommended speed for the brush and work with light to moderate pressure, moving the brush across the surface to be cleaned without forcing it. Allow the bristles to do the work; excessive pressure can shorten filament life or damage the workpiece. After use, inspect the brush and replace it if wires are excessively worn or missing.

What to consider before purchase

• Confirm your angle grinder accepts an M14 arbor thread
• Verify that stainless steel filaments are appropriate for the material (use stainless for corrosion‑sensitive metals)
• Check the grinder and brush maximum RPM compatibility
• Consider filament diameter and crimp type for the desired aggressiveness and finish

Usage recommendations

Wear appropriate personal protective equipment including eye protection, gloves and respiratory protection as required. Use steady, controlled motion and avoid side‑loading the cup; replace the brush when bristle loss or deformation affects performance.
