Abrasives

Abrasives are consumables, which is exactly why they get specified badly. They are reordered under time pressure, often from a half-legible box, and a substitution that looks equivalent — same diameter, same grit — can be rated for the wrong speed or bonded for the wrong material.

ChatMRO indexes abrasives with the attributes that actually govern selection: grit, abrasive grain, backing, bond, maximum operating speed, arbor size and the material each product is intended to cut. Bonded wheels and coated products behave differently under the same nominal grit — a 60-grit flap disc removes stock at a different rate than a 60-grit depressed-centre wheel — so grain type and bond structure matter as much as the number on the label. That makes "4-1/2 inch type 27 flap disc, 60 grit, zirconia, 5/8-11 thread" a complete query rather than a starting point.

The catalogue also carries the safety-relevant data. Every bonded wheel has a maximum RPM, and ChatMRO surfaces it against the rated speed of your grinder so a wheel is never specified beyond what the tool will spin it at. Backing material and bond type are checked the same way, since a wheel rated for one machine class can be entirely unsuitable, or unsafe, mounted on another.
