3M® Wet or Dry PSA Micro-Finishing Sanding Strips – 3/4" x 7" | 1200, 4000 & 6000 Grit

3M® Wet or Dry PSA Micro-Finishing Sanding Strips – 3/4" x 7"

Achieve exceptional surface refinement and professional-quality jewelry finishing with 3M® Wet or Dry PSA Micro-Finishing Sanding Strips. These premium pre-cut abrasive strips are designed for precision sanding, scratch reduction, and fine polishing preparation on precious and non-ferrous metals.

Featuring a convenient pressure-sensitive adhesive (PSA) backing, these strips easily attach to compatible sanding sticks, blocks, and other suitable backing surfaces. Simply peel off a worn strip and replace it with a fresh one for efficient, uninterrupted finishing.

Each strip measures 3/4" wide x 7" long, providing excellent control when working on jewelry components, metal edges, flat surfaces, and intricate details.

Designed for wet or dry applications, these micro-finishing abrasives offer a smooth, consistent cutting action and help produce uniform surface finishes. Using water during sanding can help reduce abrasive loading and carry away sanding debris.

Available in 1200, 4000, and 6000 grit, these strips are ideal for progressively refining metal surfaces before final buffing and polishing.

Key Features:

• Premium 3M Micro-Finishing Abrasives: Designed for precision sanding and consistent surface refinement.

• Wet or Dry Application: Suitable for use with or without water.

• Pressure-Sensitive Adhesive Backing: Convenient peel-and-stick design allows quick application and replacement.

• Pre-Cut Strips: Each strip measures 3/4" x 7".

• Fine and Ultrafine Abrasive Grades: Available in 1200, 4000, and 6000 grit.

• Uniform Surface Finishing: Helps reduce fine scratches and produce smooth, consistent results.

• Excellent Precision Control: Ideal for detailed jewelry finishing and working along edges and contours.

• Easy Abrasive Changes: Quickly switch between grades throughout the finishing process.

Available Grits:

• 1200 Grit / 9 Micron: Fine sanding for reducing visible scratches, smoothing metal surfaces, and preparing workpieces for ultrafine finishing.

• 4000 Grit / 3 Micron: Ultrafine surface refinement for reducing fine sanding marks and improving surface smoothness.

• 6000 Grit / 2 Micron: Extra-fine finishing for achieving a highly refined surface before final buffing and polishing.

Recommended Finishing Sequence:

For best results, begin with the appropriate abrasive grade for the condition of your workpiece and progressively move to finer grades:

1200 Grit (9 Micron) → 4000 Grit (3 Micron) → 6000 Grit (2 Micron) → Final Polishing

This progressive finishing process helps reduce sanding marks and achieve a smooth, uniform surface.

Please Note: Grit-to-micron conversions are approximate. Use the abrasive grade appropriate for your material and desired finish.
