Wire cup brush Aptel for angle grinder M14 115×14 mm steel twisted 0.5–1 pc

Aptel wire cup brush for angle grinder M14 115×14 mm with twisted steel filaments is a tool designed for aggressive surface preparation. It delivers fast removal of rust, paint, scale and burrs from metal surfaces and prepares edges and welds for subsequent finishing. The brush fits standard angle grinders with an M14 spindle and is intended for tasks that require durable, high-abrasion performance.

Advantages

The twisted steel wires provide strong abrasive action and extended service life compared with loose-filament brushes. The cup shape ensures consistent contact with flat and contoured surfaces, enabling even material removal. Its M14 thread makes the brush compatible with a wide range of angle grinders, while the compact 115×14 mm size balances removal rate and operator control. The construction resists deformation during high-speed rotation for predictable results.

Suitable for

• Removing rust and scale from steel surfaces
• Removing paint and coatings prior to repainting
• Deburring cut metal edges and weld seam cleaning
• Preparing metal parts for welding, priming or adhesive bonding

Key specifications

• Mounting thread: M14 (compatible with standard angle grinders)
• Brush diameter: 115 mm
• Working width (cup depth): 14 mm
• Filament material: steel (twisted wire)
• Filament style: twisted knot for aggressive action
• Recommended application speed: for use at the grinder’s rated speed within safety limits

How to use

Secure the brush to an angle grinder with an M14 spindle following the grinder manufacturer’s instructions and tighten the arbor nut. Hold the tool with both hands and bring the rotating cup brush to the workpiece at a shallow angle, applying light, even pressure. Move the brush steadily across the surface to avoid gouging or uneven removal. Allow the brush to do the cutting; do not force excessive pressure or side-load the cup. Stop the grinder before setting it down and inspect the brush regularly for wear or damaged filaments.

Usage recommendations

Use appropriate personal protective equipment: safety goggles or face shield, gloves, hearing protection and protective clothing. Operate the brush at the angle grinder’s recommended speed range and maintain steady motion to prevent overheating of the workpiece. Replace the brush if filaments are excessively worn or if the cup shows deformation. Keep bystanders clear of the work area and follow all safety instructions for the angle grinder.
