Match the wheel to the material
Three wheels here and they are not general purpose. Using the wrong one is slower, wears the wheel out and can be unsafe.
- Stone wheels for masonry, concrete, paving and stone. Formulated to cut hard, brittle, abrasive material.
- Metal wheels for mild steel and general fabrication.
- Inox wheels for stainless steel. The important part is what they leave out: an Inox wheel is free of iron, sulphur and chlorine, so it does not contaminate the stainless surface. A standard metal wheel embeds iron particles in stainless, and those particles rust, leaving brown staining on work that was chosen for not rusting.
If you fabricate in stainless, the Inox wheel is not a preference, it is the difference between a clean job and a corroded one.
Check the wheel before it goes on
Bonded abrasive wheels are covered by EN 12413, and the markings on the wheel carry the safety information that matters.
- Maximum operating speed, in revolutions per minute. This must be equal to or higher than the maximum speed of the grinder. A wheel run beyond its rated speed can burst.
- Dimensions and bore, which must match the machine and its flanges.
- The expiry date. Bonded wheels have a shelf life and the date is marked on the label. An out-of-date wheel goes in the bin, not on the grinder.
Inspect every wheel before fitting. Cracks, chips and any damage to the bore mean it is scrap. A wheel dropped onto a hard floor should be treated as damaged even if it looks intact.
Cutting and grinding are different jobs
A thin cutting wheel is made for slicing and is designed to be loaded on its edge. Grinding with the side of a cutting wheel puts the load in the direction the wheel is weakest, and that is a common cause of wheels shattering.
If you need to dress a weld or take material off a face, use a wheel made for grinding. The two are not the same product.
Storage
Store wheels flat and dry, supported across their whole face, and away from frost and damp. A resin-bonded wheel that has absorbed moisture can be weakened in a way you cannot see.
