3 X 24 Inch Premium Zirconia Sanding Belts, 4 Pack

$21.72 ~~$29.76~~ In stock

3x24" Industrial Grade Zirconia Grinding Belts

Our industrial grade zirconia sanding belts are a great choice for heavy duty grinding applications. Zirconia’s self-sharpening abrasive grains extend belt life up to 2.5 times longer than aluminum oxide. Zirconia fractures during use, continuously revealing sharp abrasive grain. Its durability makes it a great choice for knife makers, blacksmiths, welders, or anyone working with metals. While it will not match the longevity of ceramic abrasives, zirconia is a cost-effective alternative. Wet or dry applications. Hand built in the USA.

Violet ★★★★★ Sep 13, 2026

Bought these to strip years of old finish off a walnut slab and they chewed through it without loading up like my old aluminum oxide belts did. Four belts in the pack is nice since I didn't have to stop and reorder mid-project. They track straight on my 3x24 sander too.

Chloe D. ★★★★★ Sep 12, 2026

The zirconia grit really holds up on heavy stock removal, way longer than the aluminum oxide belts I used to burn through. I've been hogging off welds and old paint on a 3x24 sander and these still bite hard after a few sessions. Four belts for the price is a solid deal.

I ran these on my 3x24 belt sander for a full afternoon of hogging off old oak and the zirconia grains barely dulled. The self-sharpening abrasive really does keep cutting instead of just burning the wood. Four belts at this price feels like a steal.
