Wire cup brush MODECO MN-69-175 100 mm with 1/4" shank — metal wire disc brush

MODECO wire cup brush MN-69-175 is a 100 mm diameter metal wire disc brush with a 1/4" shank designed for mechanical surface preparation and cleaning of ferrous and non-ferrous metal surfaces. The brush delivers consistent abrasion for removing rust, paint and scale, deburring welds and blending edges. It mounts to rotary tools and drills that accept a 1/4" shank and is intended for tasks where controlled material removal and surface texturing are required.

Advantages

The wire cup brush provides uniform and durable metal filaments that maintain shape during use, ensuring predictable performance on a range of metal surfaces. Its 100 mm diameter and compact cup form allow access to curved and recessed areas while offering sufficient coverage for moderate surface cleaning. The 1/4" shank enables quick mounting to compatible rotary tools and drills without additional adapters.

Suitable for

• Removing rust and scale from steel and iron surfaces
• Stripping old paint and surface coatings
• Deburring sharp edges after cutting or welding
• Blending weld seams and preparing joints for finishing
• General metal surface preparation before painting or coating

Key specifications

• Brush type: cup brush with metal wire filaments
• Working diameter: 100 mm
• Shaft/shank format: 1/4" (6.35 mm) straight shank for rotary tools
• Material suitability: ferrous and non-ferrous metals
• Typical applications: rust removal, paint stripping, deburring, weld blending

How to use

Secure the wire cup brush into the chuck of a compatible rotary tool or drill with a 1/4" capacity, making sure the shank is seated and tightened according to the tool manufacturer's instructions. Operate the tool at recommended speeds for wire brushes (consult the tool and accessory speed guidelines) and apply light to moderate pressure; allow the brush to do the work rather than forcing it. Move the brush steadily over the workpiece, keeping the contact angle and speed consistent to achieve an even finish. After use, disconnect power and inspect the brush for wear or damaged filaments before storage.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, face shield, gloves and respiratory protection when working with wire brushes. Avoid excessive pressure and high peripheral speeds to reduce filament loss and minimize vibration. For delicate surfaces or thin material, test on a small area first to confirm the level of abrasion is suitable.
