52810 - Sait 3A 5-Inch Fiber Sanding Disc 36 Grit Aluminum Oxide (100-Pack)

Heavy-Duty 36 Grit Sanding Discs for Welders

For professional welders, surface preparation and post-weld finishing are critical steps that demand reliable abrasives. The Sait 52810 5" x 7/8" Fiber Disc is built to handle the rigors of the welding shop. Featuring Sait's proven 3A aluminum oxide grain, this disc is specifically formulated for general purpose grinding on ferrous metals, including mild steel and stainless steel. The 36 grit abrasive is coarse and aggressive, making it the perfect tool for leveling heavy weld beads, removing spatter, and grinding down rough surfaces quickly.

The "closed coat" design of the Sait 52810 means the abrasive grains cover 100% of the disc surface. This density allows for faster stock removal compared to open coat alternatives, which is essential when you need to strip away material efficiently. The tough fiber backing provides the necessary support to lean into the grind, allowing you to apply pressure without fear of the disc tearing or disintegrating prematurely. When paired with a hard rubber backing pad, this disc acts almost like a grinding wheel but with the flexibility to blend surfaces smoothly.

Welders appreciate the consistency of Sait abrasives. The 52810 maintains its cutting edge longer thanks to its superior resin bonding, which resists the heat generated during aggressive grinding. This 100-pack ensures you have a steady supply of fresh discs on hand for large fabrication projects, structural steel work, or automotive repair. It is an essential consumable for any welder's toolkit, providing the bite needed to clean up messy welds and prepare metal for painting or further finishing.
