3M 7100041315 Abrasive Sheet 400 Grit 9x11 Silicon Carbide

Product Description

The 3M 7100041315 is a silicon carbide abrasive paper sheet designed for fine finishing and surface preparation tasks in trade and light industrial applications. Measuring 9 inches x 11 inches with a 400 A-weight grit rating, this sheet delivers consistent cut and smooth finish on wood, metal, composites, and painted surfaces. Silicon carbide is a sharp, fast-cutting mineral well suited for sanding hard materials and finishing between coats. Sold in boxes of 100 sheets, this format suits high-volume finishing operations where sheet consumption is steady and controlled.

This abrasive sheet is commonly used in bodywork, cabinetry, metal fabrication, and general surface prep where a fine 400-grit finish is required before final coating or polishing. The A-weight paper backing provides flexibility for hand sanding flat and slightly contoured surfaces. It is used by finishing carpenters, automotive refinish technicians, metal fabricators, and general contractors performing surface prep work prior to paint or topcoat application.
