Q: What cutting advantages does precision-shaped ceramic grain offer?
A: The triangular precision-shaped ceramic grain slices through material more efficiently, cutting roughly 30 percent faster and lasting about 2× longer than conventional ceramic abrasives while continuously self-refreshing its sharpness during use.

Q: What applications is disc 33413 best suited for?
A: This disc is built for medium to heavy-duty stock removal tasks such as weld grinding, blade chamfering, paint and coating stripping, deburring, and spot weld or door-skin removal in industrial and automotive metal prep work.

Q: How is the disc attached to power tools?
A: It mounts using a hub and retainer-nut system, providing fast, secure attachment to angle grinders and ensuring safe, stable operation.
