3/4x20 1/2" 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 and quick cut makes it a great choice for welders or anyone working with metals. We use a special heavy but flexible backing for tight contours of hand held air sanders. Hand built in the USA.

Christopher ★★★★★

These fit my 3/4 inch air file perfectly and the 20 1/2 inch length gives me plenty of belt to work with on long welds. Ten in a pack means I'm not running to the store mid-job, and they've outlasted the cheap belts I used before.

Jason O. ★★★★★

Ten belts for the price of a couple elsewhere, and the zirconia grit really does stay sharp longer than the aluminum oxide ones I used to run. I've been using them on my 3/4 inch wide file sander for shaping knife blanks and they hold up great.

Steven B. ★★★★★

Cut through a stubborn weld line on 3/8 steel in about half the passes my old belts needed, and these zirconia grains keep biting instead of glazing over. The 3/4-inch width sits perfectly in my 1x30 sander without any tracking fuss. Right out of the pack, all ten belts were true and flat—no wobble
