3M Scotch-BriteTM Precision Heavy Duty Series Hook & Loop Sanding Disc, 4.5in Disc Diameter, Aluminium Oxide Abrasive - 7100358896

This hook & loop sanding disc is a non-woven, multi-purpose abrasive pad designed for surface conditioning tasks in industrial settings. It combines aluminium oxide mineral with a conformable black non-woven web to perform cleaning, blending, deburring and finishing at elevated spindle speeds, and is intended for use on powered grinders and sanders in automation, electronics, electrical and mechanical workflows.

Features & Benefits

• Aluminium oxide abrasive gives sustained cutting performance
• Non-woven web reduces risk of gouging during finishing
• Centre hole design enables secure attachment to tools
• Rated for up to 13,300 rpm for high-speed operations
• Medium grit delivers balanced material removal and finish

Applications

• Suitable for light grinding and deburring on mild steel components
• Ideal for blending and radiusing edges on fabricated parts
• Used for refining finishes on aluminium assemblies
• Can be used for cleaning and preparing electrical contact surfaces
• Suitable for automated sanding stations with centre-post mounting

How should I select backing pads for use with these discs?

Use a compatible hook-and-loop back-up pad sized for 4.5in discs and rated for the intended rpm

choose a firmer pad for higher-pressure material removal or a softer pad for contour finishing.

What operational advantage does the non-woven web provide?

The open-fibre structure maintains a consistent finish by reducing clogging and conforming to complex shapes, lowering the likelihood of undercutting delicate features.

Are these discs suitable for high-volume production?

Yes, packaged in quantities of 50 per pack to minimise changeovers and support continuous processing workflows.

Which grit should I choose for edge-breaking versus surface blending?

Medium grit is recommended for balanced edge-breaking and blending

coarser or finer grades adjust aggression and final surface texture accordingly.

What mineral composition is used and how does it affect wear?

The abrasive mineral is aluminium oxide, which provides Durable cutting action appropriate for general metalworking and long wear in multi-purpose applications.
