What Continuous Rim Diamond Grinding Wheel Is For
The plant specification sheet describes this tool as for smooth and fast grinding concrete. That is exactly where it belongs, and where it stops.
The specification table lists 4 sizes, Item IDs CA105CRW to CA125CRW.
Inside Diamond Grinding Cup Wheels there are 10 items to choose between. This one is the continuous rim for smoothing concrete surfaces option — the comparison further down this page sets it against the others.

Use Guide
Confirm the fit
Check diameter, bore and segment dimensions against the table above and against your machine.
Set the parameters
Start at the machine builder's figures for your material, then adjust feed until the cut runs quiet and the surface stays clean.
Keep it free-cutting
If the tool stops cutting and the face goes shiny, it has glazed. Dress it, then tell us — that means the bond should change.
