3M PSA Silicon Carbide Sanding Discs – 6" Diameter | 240, 400 & 600 Grit | Wet or Dry

3M PSA Silicon Carbide Sanding Discs – 6" Diameter | 240, 400 & 600 Grit

Achieve smooth, consistent surfaces and professional-quality metal finishing with 3M PSA Silicon Carbide Sanding Discs. Designed for precision sanding and pre-finishing applications, these premium abrasive discs feature a pressure-sensitive adhesive (PSA) backing for secure attachment to compatible 6-inch flat flanges.

Manufactured with silicon carbide abrasive, these discs provide effective cutting action and controlled surface refinement, making them particularly suitable for non-ferrous and precious metals, including gold, silver, brass, and copper.

Designed for both wet and dry sanding applications, 3M PSA Sanding Discs offer excellent versatility for jewelry fabrication, metalworking, scratch removal, and polishing preparation.

Available in 240, 400, and 600 grit, these 6-inch abrasive discs allow jewelers and metalworkers to progressively refine metal surfaces, reduce sanding marks, and prepare components for final buffing and polishing.

Key Features:

• Premium Silicon Carbide Abrasive: Provides effective cutting action and consistent surface finishing.

• Pressure-Sensitive Adhesive (PSA) Backing: Allows convenient attachment to compatible 6-inch flat flanges.

• Wet or Dry Applications: Suitable for both wet and dry sanding and pre-finishing.

• Ideal for Precious Metals: Excellent for preparing gold, silver, and other non-ferrous metals for polishing.

• 6-Inch Diameter: Provides generous abrasive coverage for efficient surface finishing.

• Three Grit Options: Available in 240, 400, and 600 grit for progressive surface refinement.

• Smooth, Uniform Finishing: Helps remove scratches, reduce sanding marks, and prepare metal surfaces for final polishing.

• Maximum Operating Speed: 3,000 RPM.

Available Grits:

• 240 Grit (Medium-Fine): General surface preparation, removing moderate scratches, and smoothing metal surfaces before finer sanding.

• 400 Grit (Fine): Refining surfaces, reducing sanding marks, and preparing jewelry components for final finishing.

• 600 Grit (Extra Fine): Fine surface smoothing and polishing preparation for a more uniform finish.

Ideal Applications:
