3M Precision Shaped Grain Adhesive-Backed/PSA Sanding Disc Cutting Disc, 150 mm, 180+ Grade, 50 Grit

This adhesive-backed/PSA sanding disc is a cloth-backed abrasive designed for heavy stock removal and finishing tasks across wood, metal and composite substrates. It incorporates precision-shaped grain to maintain cutting Ability as the mineral fractures, and an anti-static treatment to reduce electrically charged swarf during sanding operations. The product is intended for use with random orbital sanders and vacuum-extraction back-up pads to support cleaner working environments.

• Precision-shaped grain delivers continuous fracture and long life
• Open-coat construction reduces loading and sustains cut rate
• Anti-static treatment neutralises charged swarf for cleaner sanding
• Cloth backing offers wear resistance with flexible conformity
• Hookit attachment enables Rapid disc changes and minimal downtime

• Suitable for heavy stock removal on aluminium components
• Ideal for blending and finishing hardwood and softwood surfaces
• Used for preparing fibreglass and gelcoat prior to assembly
• Can be used with vacuum-capable orbital sanders for dust control
• Suitable for composite trimming in electronics and mechanical workshops

It performs on wood, metals and composites, with finer grades recommended for blending and finishing on aluminium and hardwoods.

The precision-shaped grain continuously fractures to form fresh cutting edges, resulting in even wear and prolonged abrasive life.

It uses a hook-on PSA system for quick attachment and pairs with multi-hole back-up pads and vacuum-equipped random orbital sanders for improved extraction.

An open-coat mineral layout limits loading while an anti-static treatment reduces adherence of electrically charged swarf to surfaces and equipment.
