FAQs

What materials is this disc designed for?

This disc is specifically designed for cutting stainless steel, inox, and aluminum. It is ideal for extrusions, welds, sections, trunking, and pipes made from these materials.

Can I use this disc for cutting other metals like mild steel?

While it may cut mild steel, it is optimized for stainless steel, inox, and aluminum. Using it on other materials may reduce its lifespan and cutting efficiency.

What is the advantage of an extra-thin kerf?

An extra-thin kerf (1.2mm) means the disc removes less material during cutting. This requires less power from the grinder, results in less material waste, and typically produces a cleaner cut with fewer burrs.

Is this disc suitable for cutting wood or masonry?

No, this disc is not designed for cutting wood, masonry, or concrete. Using it for such purposes can be dangerous and will damage the disc.

What size angle grinder does this disc fit?

This disc has a 125mm diameter and a 22mm bore, making it compatible with standard 125mm angle grinders featuring a 22mm spindle.

How should I store the disc when not in use?

Store the disc in a dry environment, away from moisture, to prevent rust or corrosion. Keep it in its original packaging or a protective case if possible.

Troubleshooting

Disc is not cutting efficiently.

Ensure the disc is correctly mounted and spinning at the appropriate RPM for the grinder. Check if the material being cut is within the disc's specifications (stainless steel, inox, aluminum). Avoid applying excessive sideways force.

Excessive sparking or heat.

Verify the disc is not damaged and is the correct type for the material. Ensure the grinder's ventilation is not blocked. Reduce the cutting speed or pressure if necessary, or consider a different disc if the material is harder than expected.

Disc chipping or breaking.

This can indicate a damaged disc or excessive force. Immediately stop use and inspect the disc. If any damage is found, replace the disc. Ensure the material is properly supported and avoid twisting the disc during the cut.

Setup, Compatibility & Care

Setup: Ensure the angle grinder is turned off and unplugged before mounting the disc. Align the disc's 22mm bore with the grinder's flange and secure it using the appropriate flange nut and spanner. Always check that the disc is rated for the grinder's RPM.
