HUMMEL BELT 7 7/8" X 29 1/2" ZIRC CLOTH

The zirconia alumina cuts through the old polyurethane on my floors like butter, and it's held up through three full rooms without shredding. I'm honestly impressed how flat it stays on the drum, no slipping or vibration at all.

Installed this 7 7/8 x 29 1/2 inch belt on my Hummel and it cut through the old finish way faster than the generic stuff I’ve used before. The zirconia cloth really holds up without loading up, even on some tricky oak.

The zirconia alumina grit held up through three full rooms of oak without loading up or shedding, which is exactly what I needed. My floor sander ran smoother with this belt than with the cheaper aluminum oxide ones I've tried before, and the size fit perfectly without any adjustments.
