3M Precision Shaped Grain Adhesive-Backed/PSA Sanding Disc Cutting Disc, 152.4 mm, 120 Grade, 50 Grit

This adhesive-backed/PSA sanding disc is a precision abrasive designed for heavy stock removal and finishing in industrial environments. It combines a Durable cloth backing with precision-shaped grain to maintain cutting action on metals, wood and composites while reducing loading and managing swarf. The product is intended for use with hook-and-loop or adhesive-back mounting systems and is suitable for applications where effective dust extraction and consistent abrasive life are required.

• Precision-shaped grain delivers fast-cutting performance and longer life
• Anti-static treatment reduces static charge and swarf adhesion
• Open-coat construction resists loading and sustains cutting rate
• J-weight cloth backing balances flexibility with wear resistance
• Compatible with multi-hole extraction systems to reduce dust

• Suitable for heavy stock removal on metal components
• Ideal for surface preparation of aluminium and composites
• Used for blending and finishing hardwood and softwood panels
• Can be used with vacuum-backed orbital sanders for dust control
• Suitable for sanding gelcoat and fibreglass parts in production lines

The disc uses a J-weight cloth backing that provides wear resistance while allowing the disc to conform to slightly contoured surfaces.

The precision-shaped grain fractures to form new cutting edges during wear, producing consistent abrasive action and extended service life.

An anti-static treatment helps neutralise charge on swarf, and the multi-hole extraction pattern is intended to be used with a vacuum system to reduce dust and loading.

It is designed for use with 3M hook-and-loop and adhesive-backed PSA mounting methods and with appropriately matched back-up pads.
