3M 7010359742 Abrasive Belt 400 Grit 77x1 Inch Silicon Carbide

Product Description

The 3M 7010359742 is a silicon carbide abrasive sanding belt built on a heavy YF-weight polyester cloth backing with closed coat construction. Measuring 77 inches long and 1 inch wide, it delivers aggressive cutting action combined with a fine surface finish. The closed coat layout increases grain density across the belt face, making it well suited for demanding metal finishing work. Cork particles mixed with the silicon carbide abrasive help produce the characteristic blue finish required on stainless steel surfaces. Resin bonding holds the mineral to the backing and resists heat-related deterioration, extending belt service life. Licensed HVAC, plumbing, and metal fabrication shops will find this belt suitable for high-cycle sanding operations.

This belt is designed for metal surface sanding and final cosmetic polishing, including applications where a specific surface finish standard must be met on stainless steel. The flexible polyester cloth backing conforms to contoured and curved workpieces, maintaining consistent abrasive contact across irregular profiles. It performs well on both flat stock and shaped components in fabrication, maintenance, and finishing environments. The waterproof backing allows debris and swarf to be cleared easily without loading the abrasive prematurely.
