CARTRIDGE ROLL

The diameter and length markings are printed clearly right on the roll, which saved me from digging out my calipers every time. Fits my rotary tool drum without any wobble, and the grit holds up through several sessions.

The length measurement marks on the roll make sizing quick, and the cardboard core stays rigid even after a few uses. Took a minute to get the hang of reading the diameter line, but the fit ended up exactly right.

The outside diameter measurement was spot on, which made fitting it into my sander a breeze. I've been using it on some old wood and it's holding up much better than the cheap rolls I tried before.
