3M Adhesive-Backed/PSA Sanding Disc, 203mm Disc Diameter, 40 Grit size - 7100284565

This adhesive-backed/PSA sanding disc is a precision-shaped grain abrasive designed for heavy stock removal and finishing in industrial settings. It combines a cotton cloth backing with a pressure-sensitive adhesive attachment to deliver consistent cutting on metals, timber and composite substrates while supporting dust extraction workflows in production and maintenance environments.

Features & Benefits

• Precision-shaped grain for fast cutting and extended life
• Open coat construction reduces loading for sustained performance
• Anti-static treatment helps manage electrically charged swarf
• Cloth backing offers wear resistance and conformability
• PSA attachment enables Rapid disc changes and secure mounting

Applications

• Suitable for aggressive metal stock removal in fabrication shops
• Ideal for blending and finishing aluminium panels
• used with angle grinders for surface preparation on steel
• Can be used for sanding hardwoods and composite repairs
• used with vacuum-backed orbital sanders for cleaner operations

What role does the anti-static treatment play during operation?

It neutralises static generated while sanding, reducing swarf adherence to the disc, workpiece and machinery when used alongside an effective dust collection system.

How does the abrasive maintain cutting performance over time?

The grain fractures as it wears to continuously create Sharp cutting edges, preserving cut rate and consistency across the disc life.

Which attachment and extraction setups are recommended for best results?

Pair with a multi-hole back-up pad designed for extraction and a random orbital Sander with vacuum to improve dust capture and prevent clogging.

What backing materials and attachment options are available beyond the adhesive version?

Variants include different cloth backings and alternative attachment systems such as hook-and-loop or Stikit for compatibility with diverse pad types.
