Choosing a wide belt

Grain. Open-coat aluminum oxide is the workhorse for solid wood, plywood and veneer. Zirconia and ceramic are for steel, stainless and aluminum on Timesaver-style metal finishing machines, and for high-production hardwood lines where belt life matters more than cost.

Backing. X-weight cloth is standard for wide belts; heavier Y-weight polyester for wet or high-pressure metal work.

Joint. We build wide belts on a bi-directional butt splice with a tape joint, so there's no bump in the finish and no need to track direction. Our guide to lap vs. butt splices explains the difference.

If your machine breaks belts or leaves chatter marks, read Common Wide Belt Sander Problems before ordering – it's usually tracking or tension, not the belt.

Sanding belts for drum-style floor sanders, sold in 10 packs. We stock the five sizes that fit nearly every rental and professional machine: 8" x 19" for the Clarke EZ-8, 7-7/8" x 29-1/2" for the American Sanders and Clarke 8" drums, 9-7/8" x 29-1/2", 11-7/8" x 29-1/2" and 11-7/8" x 31-1/2" for 10" and 12" drum machines. Open-coat aluminum oxide is the standard for hardwood flooring; zirconia is available for heavy cuts on old finish.

Grit sequence for refinishing a floor

Start at 36 grit to remove old finish and level boards, move to 60, then 80, then finish at 100 or 120 before stain or sealer. Don't skip grits – the scratches from 36 grit won't come out with 100. Our guide on how to sand a floor with a drum sander covers technique and edge work.
