3M Precision Shaped Grain Adhesive-Backed/PSA Sanding Disc Cutting Disc, 152.4 mm, 60 Grade, 50 Grit

This adhesive-backed/PSA sanding disc is a 150mm abrasive disc designed for industrial material removal and finishing. It employs precision-shaped grain to maintain cutting performance across metals, woods and composites while a J-weight cloth backing offers a balance of durability and flexibility for demanding sanding tasks in automation, electronics, electrical and mechanical environments.

• Precision-shaped grain provides continuous fracturing and sustained cut
• Open coat construction reduces loading and extends abrasive life
• Anti-static treatment neutralises charge to reduce swarf adhesion
• Hookit-compatible attachment enables Rapid disc changes and uptime
• J-weight cloth backing combines wear resistance with flexibility

• Suitable for heavy stock removal on metalwork and fabrication
• Ideal for smoothing hardwood components in mechanical assemblies
• Used for preparing aluminium surfaces before bonding or coating
• Can be used for gelcoat and composite surface blending tasks
• Suitable for use with vacuum-equipped random orbital sanders

The multi-hole extraction pattern is engineered to work with vacuum back-up pads and dust collection to remove debris and reduce loading when used with an appropriate extraction system.

The precision-shaped mineral is effective on ferrous and non-ferrous metals, hardwoods, softwoods and composite laminates, providing high removal rates on stubborn materials.

A hook-and-loop style Hookit attachment is incorporated to speed disc replacement and maintain stable fitment on compatible back-up pads.

The open coat grain layout prevents clogging and the grain fractures to renew cutting edges, resulting in longer service life under heavy-stock removal conditions.
