Abrasives & Grinding Wheels

Coated and bonded abrasives are a consumable category where the safety test is the hard requirement: cutting and grinding wheels must be tested to the EN 12413 / OSHA marking rules for max RPM and burst speed. Price differences come from abrasive grain (A/O alumina, Zr, silicon carbide, CBN/diamond), resin system and backing cloth, not from disc colour.

Specification reference

Attribute	What to specify
Diameter	100–350 mm cutting/grinding; 350–1500 mm diamond blades
Thickness	1.0 / 1.6 / 2.5 / 3.0 / 6.0 mm common
Max RPM	Printed per size, e.g. 100 mm at 15,300 rpm — verify against the machine
Grain	A (carbon steel), ZA/Zr (stainless), GC (cast iron / stone), CBN (hardened steel)
Reinforcement	Double fibreglass mesh on cutting discs; cloth backing count on belts
Shelf life	Resin wheels typically 3 years from manufacture, printed on the label

Typical MOQ: Typically 10,000–30,000 pcs per specification for OEM printing; 2,000 pcs for neutral bulk. Typical lead time: 20–35 days (resin cure cycle and test batch take real time).

Questions buyers ask

Which abrasive should I buy for stainless steel fabrication?

Use a zirconia-alumina (ZA) or ceramic grain wheel and specify iron-free / low-S content for stainless so you do not cause surface contamination rust. Pair it with the correct hardness grade and the max RPM printed on the disc.

Is a cheap cutting disc actually more expensive?

Usually yes: thinner reinforcement and lower-quality resin cut faster but burst earlier and increase downtime and injury exposure. Compare discs by cut-count per unit, printed max RPM and the EN 12413 / ANSI test evidence, not by unit price.
