Wire cup brush MILWAUKEE S6 19x28x72 mm stainless steel crimped wires, 0.35 mm, pack of 3

MILWAUKEE wire cup brush S6 with dimensions 19×28×72 mm features 0.35 mm stainless steel crimped wires and is supplied as a pack of 3. It is designed for surface preparation tasks such as removing rust, paint and scale, deburring edges and cleaning weld seams on ferrous and non-ferrous metal surfaces. The cup shape and crimped-wire construction provide a balance between aggressiveness and surface finish while the stainless steel wires resist corrosion during use and storage.

Advantages

The MILWAUKEE S6 wire cup brush combines compact dimensions with durable stainless steel crimped wires that maintain shape under rotational load. The crimped-wire pattern increases flexibility compared to straight-wire brushes, reducing the risk of gouging while still delivering effective material removal. Supplied in a pack of three, the set allows for quick replacement and continuous work without interrupting the task to resharpen or clean a single brush. The cup form concentrates brushing action for efficient cleaning of flat areas and recessed features.

Suitable for (tasks / use cases)

• Removing rust, scale and old paint from metal surfaces
• Deburring cut edges and small workpieces
• Cleaning and preparing weld seams and joints
• Surface preparation before painting or coating
• Light surface finishing and blending of welds

When it may not be suitable

This stainless steel cup brush is not intended for use on delicate, soft or highly polished surfaces where abrasion would cause visible damage. It may be too aggressive for thin sheet metal if used at high feed pressure or with high-speed rotary tools, risking deformation of the workpiece. For non-metal materials such as plastics, painted composites or wood, choose a softer brush type to avoid surface scoring.

Key specifications

• Brush shape: cup
• Dimensions: 19 × 28 × 72 mm
• Wire material: stainless steel
• Wire type: crimped wires
• Wire diameter: 0.35 mm
• Pack quantity: 3 pieces
• Intended mounting: compatible with bench or handheld rotary tools with matching arbor

How to use

Install the cup brush on a rotary tool or bench grinder spindle that matches the brush arbor, ensuring the tool is unplugged or powered off during fitting. Securely fasten the brush according to the tool manufacturer’s instructions and check for wobble before operating. Start at low speed to confirm correct mounting, then increase to the recommended operating speed while applying light, even pressure. Move the brush across the surface in steady passes; avoid concentrating on one spot to prevent overheating or excessive material removal. After use, clean metallic debris from the brush and store in a dry place to maintain wire condition.

What to consider before purchase

• Ensure your rotary tool or bench grinder accepts the brush dimensions and arbor type
• Confirm stainless steel wire is suitable for your workpiece material to avoid contamination or unwanted surface effects
• Assess whether 0.35 mm wire thickness and crimped-wire style provide the right balance of aggressiveness and surface finish for your application
• Consider stocking replacement packs if you perform frequent or heavy-duty cleaning tasks

Usage recommendations

Use appropriate personal protective equipment including eye protection, gloves and a dust mask. Operate the brush at recommended speeds, apply light pressure, and allow the brush to do the work to achieve consistent cleaning without damaging the workpiece.
