3M Adhesive-Backed/PSA Sanding Disc, 203mm Disc Diameter, 120 Grit size - 7100287537

This adhesive-backed/PSA sanding disc is a net-backed abrasive designed for general sanding, stock removal and surface preparation across multiple substrates. It uses a blend of aluminium oxide and precision-shaped ceramic mineral to balance cutting performance and finish, and its open net backing enables dust extraction when used with a suitable backing pad and vacuum system.

Features & Benefits

• Precision-shaped ceramic grain improves cut rate and longevity
• Net backing enables effective dust extraction with vacuum
• Hookit-compatible loops allow Rapid disc changes without alignment
• Proprietary patterned coating reduces loading during sanding
• Available in a range of grit grades including 120 grit

Applications

• Suitable for automotive bodywork preparation and paint removal
• Ideal for scuffing and intermediate sanding of composites
• Used for sanding primers, lacquers and sealers prior to refinishing
• Can be used for metal deburring and whitewood surface work

How should the discs be stored to preserve performance?

Store in the original packaging at 16°C to 26°C and 35 to 50% relative humidity on a first-in, first-out basis to avoid accelerated degradation.

What backing system is required for dust extraction?

A supporting tool with a Hookit-compatible backup pad paired with a vacuum extraction system is needed to utilise the net backing for dust removal.

Which mineral composition affects both cut and finish?

A blend of aluminium oxide and 3M’s proprietary precision-shaped ceramic grain provides a balance between stock removal and surface finish.

What operational speed limits apply for safe use?

Maximum orbits per minute depend on disc diameter and tool

larger-diameter discs operate at lower maximum OPM to match tool specifications.

How are disc sizes and attachment handled for custom requirements?

Hookit discs are offered in multiple standard sizes and additional dimensions may be available as make-to-order options — contact sales for availability.
