3M Adhesive-Backed/PSA Sanding Disc, 150mm Disc Diameter, 180+ Grade - 7100281804

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.

Features & Benefits

• 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

Applications

• 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

What substrate types will this disc handle effectively?

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

How does the abrasive maintain cutting performance over time?

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

What attachment and dust-management options are compatible?

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.

How does the product manage dust and swarf during sanding?

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