Sanding Belts, Discs & Finishing Supplies

Which belt for which machine

• Portable belt sanders – 3x18, 3x21, 3x24, 4x21, 4x24, 4x36. Aluminum oxide for wood, zirconia for metal.
• Bench belt sanders – 1x30, 1x42, 2x42, 4x36, 6x48. The 1x30 in fine grits doubles as a knife sharpening belt.
• 2x72 belt grinders – see our knife making collection for ceramic, zirconia and surface conditioning belts.
• Edge sanders – 6x80, 6x89, 6x108 and longer; open-coat aluminum oxide resists loading on edge work.

Not sure what you have? Measure the width and the full circumference and read how to measure a sanding belt. Custom sizes ship in about three business days with no minimum.

Those sizes are 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.
