Description

The Yato cup brush M14 100 mm brass is a crimped wire cleaning brush for angle grinders, designed for gentle but effective surface work. Brass wire is softer than steel wire, which reduces the risk of scratching on delicate workpieces and on soft metals such as copper, brass and aluminium.

The cup body spreads contact evenly and improves control on large surfaces. The Ø100 mm size gives good coverage, and the M14 fitting fits most 115–125 mm angle grinders. Crimped wire cuts evenly without the aggressiveness of angular knotted wire, which makes it excellent for removing oxidation, paint and adhesive residues and light dirt.

Brass wire naturally produces few sparks and does not cause iron contamination on the surfaces being worked. This is important when treating non-ferrous metals, chrome-plated or coated parts, and threads and sealing surfaces where the surface profile should be preserved.

With the right working technique (a shallow angle, light to moderate pressure and the recommended speed) you get an even, controlled result. Regular breaks and checking the condition of the brush extend its life and ensure the finish.

Intended use:

• Removing oxidation and surface dirt from non-ferrous metals: Brass wire removes oxide layers from copper and brass and light oxide from aluminium without deep scratches. This is useful, for example, on electrical connectors, pipe components and decorative parts where you want to keep the visual quality and dimensions of the surface.

• Gentle cleaning of paint and adhesive residues: Crimped wire removes loosely adhering coatings from wood, soft metals and coated components in a controlled way. Brass reduces the risk of over-keying, so the base stays clean before new coating or bonding.

• Cleaning up threads and sealing surfaces: Dirt built up in threads, dried compounds and surface rust come off without rounding the thread crests when you use light pressure and even sweeps. This improves assembly quality and makes later maintenance easier.

• Finishing decorative and machine parts: The brush creates an even, fine microstructure on chrome-plated, nickel-plated or anodised surfaces when a light polishing/cleaning effect is needed without the aggressive cut of steel wire.

Features:

• Diameter: 100 mm – Good coverage on large surfaces with controlled handling.

• Fixing: M14 thread – Compatible with most angle grinders.

• Bristle material: Brass wire (crimped) – Softer cut; low sparking and no iron contamination.

• Structure: Cup brush – Even contact and a clean finish without the edge digging in.

• Applications: Oxidation, paint and adhesive residues, light dirt – Especially non-ferrous metals and delicate surfaces.

• Speed: Follow the maximum value marked on the product – Prevents overheating and premature wear of the wires.

• Safety: Guard, eye and respiratory protection – To reduce risks at work.

Yato cup brush M14 100 mm brass: instructions for use:

1. Fitting: Disconnect the angle grinder from the power supply. Fit the brush to the M14 thread and tighten according to the manufacturer’s instructions. Make sure the guard is in the correct position.

2. Test run: Run the brush without load for a few seconds; stop if there is abnormal vibration or “runout”.

3. Working: Hold the brush at a shallow angle and use light to moderate pressure. Make even sweeps; avoid long point contact.

4. Breaks: Stop regularly, remove loose material and let it cool. Check the wires for wear and the condition of the cup.

5. Maintenance: Clean off dust and swarf, dry and store in a dry place. Do not straighten bent wires.

Warnings:

• Always wear safety glasses/a visor, a respirator suited to the dust level, protective gloves and, if necessary, ear defenders.

• Do not exceed the maximum speed permitted for the brush/machine.

• Do not use a damaged or unbalanced brush.

• Keep flammable materials away from the work area.

• Not for use in explosive atmospheres. Keep out of the reach of children.

Frequently asked questions (FAQ):

Why choose brass wire instead of steel wire?
Brass is softer, sparks less and is suitable for delicate surfaces and non-ferrous metals without the risk of iron contamination. It leaves a more even, finer roughness.

Can the brush be used on stainless steel?
Yes, but the removal rate is more moderate than with steel wire. Brass does not spread iron particles, which helps preserve the corrosion resistance of the surface.

Is it suitable for aluminium?
Yes. Use light pressure and a moderate speed so that the surface does not get scratched or overheat.

When is the brush replaced?
When wires are missing, the cup is damaged or vibration clearly increases, the brush should be replaced to ensure safety and a consistent finish.
