3M Precision Shaped Grain Adhesive-Backed/PSA Sanding Disc Abrasive Disc, 203.2 mm, 180+ Grade, 180 Grit

This adhesive-backed/PSA sanding disc is a 203mm abrasive intended for heavy stock removal and finishing across multiple substrates. It combines precision-shaped grain mineral on a cotton cloth backing with a hook-and-loop style attachment system to support mechanical sanding operations where dust extraction and continuous cut are required. The product is engineered for use with vacuum-capable random orbital sanders and back-up pads in industrial settings.

• Precision-shaped grain delivers Rapid material removal and consistent wear
• Anti-static treatment reduces electrostatic cling and dust build-up
• Open coat construction limits loading for sustained cutting performance
• Cotton cloth backing provides durability while remaining flexible
• Multi-hole extraction compatibility improves dust control when vacuums are used
• PSA adhesive attachment enables quick, secure disc changes

• Suitable for heavy stock removal on aluminium panels in automation assemblies
• Ideal for smoothing fibreglass and gelcoat on composite housings
• Used for preparing hardwood and softwood surfaces in mechanical fixtures
• Can be used for surface blending during automotive refinishing tasks
• Used with vacuum orbital sanders for metal deburring in electrical enclosures

An anti-static surface treatment neutralises static charge so swarf and dust are less likely to cling to the disc, workpiece or machinery during sanding of wood.

The mineral fractures predictably as it wears, creating fresh Sharp edges that preserve cut rate and extend usable life under heavy removal.

The disc is provided with a PSA adhesive backing compatible with hook-and-loop style back-up pads for Rapid changeover.

A J-weight cotton cloth backing is used to combine wear resistance with the flexibility necessary for conforming to contoured parts.
