Description

The Yato knotted cup brush M14 60 mm stainless steel is a brush for angle grinders, designed for heavy cleaning and mechanical preparation of metal surfaces. The knotted stainless steel wire forms stiff tufts that bite efficiently into thick rust, flaking layers of paint and welding slag. The cup body stabilises contact and spreads the load evenly, so the work progresses in a controlled way even on large surfaces.

The Ø60 mm diameter gives good coverage without sacrificing control. This size is suitable for sheet surfaces, profiles and seam areas where you need brisk material removal and an even roughness before primer or coating. The M14 thread is compatible with common angle grinders in the 115–125 mm class.

Using INOX wire reduces the risk of cross-contamination from iron particles on stainless steel surfaces compared with carbon steel wire. This is an advantage in maintenance, renovation and pre-cleaning of equipment parts in the process industry, where further treatment of surfaces requires a clean, uniform bonding surface.

With the right speeds and working technique (light to moderate pressure, even sweeps) you get a controlled finish without needless loss of base material. Regular breaks prevent overheating and extend the life of the brush.

Intended use:

• Heavy removal of rust and paint: Knotted INOX wire removes thick layers of corrosion and coating quickly. The cup construction reduces the edge digging in and helps keep the finish even on large steel and stainless steel surfaces. Useful before sandblasting, grinding or priming.

• Cleaning up weld spatter and slag: The knotted tufts withstand point loads and remove spatter and heat-zone oxides before passivation or painting. A more even surface reduces the need for grinding later.

• Keying the surface before coating/bonding: Mechanical keying improves the adhesion of coatings and adhesives. Ø100 mm offers a good compromise between coverage and control, which speeds up preparation on production line jobs.

• Maintenance outdoors and in damp conditions: Stainless wire withstands splashes and changes in the weather. Suitable for railings, stair parts, tanks, machine components and steel structures where minimising cross-contamination is important.

Features:

• Diameter: 60 mm – Good coverage for larger surfaces, yet controllable.

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

• Bristle material: Stainless steel wire (INOX), knotted – Aggressive cut, durability under point loads.

• Structure: Cup brush – Stable contact, even finish, little edge digging in.

• Applications: Rust, paint, oxides, slag, spatter – Cleaning and keying before further treatment.

• Speed: Follow the maximum value stated on the packaging – To prevent overheating and damage.

• Compatibility: 115–125 mm angle grinders – A guard must be used.

Yato knotted cup brush M14 60 mm stainless steel: instructions for use:

1. Fitting: Disconnect the machine 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 it briefly without load; 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 and inspection: Stop regularly, remove loose material and assess wear. Replace the brush if knotted tufts are missing, the wire has shortened unevenly or the cup is damaged.

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

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 speed permitted for the brush/machine.

• Do not use a damaged or unbalanced brush.

• Keep flammable materials away from the spark area; sparks can come from the workpiece.

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

Frequently asked questions (FAQ):

Why knotted wire and not crimped wire?
Knotted wire is stiffer and more aggressive: it removes thick rust and slag faster. Crimped wire is more moderate, for an even roughness.

Can the brush be used on stainless steel?
Yes. INOX wire reduces iron contamination. Clean the surface after use.

Is the brush suitable for aluminium?
Yes, for light oxide removal and keying. Avoid excessive pressure and heat so that the surface is not deeply scratched.

When should the brush be replaced?
When the knots have shortened unevenly, tufts are missing or vibration increases, replace it with a new one.
