This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If manually operated
Non-numerically controlled cermet finishers go to other category.
If pure ceramic components without metal
Cermets must contain sufficient metal; otherwise ceramic articles apply.
If for sawing/grinding cermet as stone-working
If treated primarily as stone/ceramic sawing rather than metal finishing.
