Aurora P. ★★★★★ Oct 22, 2026

These belts handled a full day of grinding down steel welds without loading up once. The heat reduction from the closed coat design is no joke, my work piece stayed cooler than with my old belts. Exactly the industrial grade I needed for metal work.

Ella S. ★★★★★ Oct 21, 2026

I was skeptical about the closed coat design, but it really does resist loading up on stainless steel. Cut through a bunch of rusty angle iron without the belt glazing over, which is a huge time saver. Definitely grabbing another pack for the shop.

These belts handled the 4x36 inch size perfectly on my grinder, and the closed coat aluminum oxide held up through several steel projects without tearing. I’m really impressed with how well they remove material without overheating the metal.
