3M 732U Series Grinding Disc, 152.4mm Disc Diameter, 1000 Grit size - 7100335437

This grinding disc is a fine abrasive sanding solution designed for industrial surface preparation and finishing in mechanical, electrical and automation settings. It combines precision-shaped abrasive mineral on a paper backing with a resin bond to deliver consistent cutting and a controlled finish when used on metals, painted surfaces, composites and wood.

Features & Benefits

• Precision-shaped grain delivers Faster cutting and cooler operation
• Resin bond extends disc life for reduced changeovers
• Up to 99% dust extraction when used with extraction-compatible pads
• Anti-load coating limits clogging for consistent performance
• Hookit attachment enables Rapid on/off disc replacement

Applications

• Suitable for finish sanding of painted automotive panels
• Ideal for metal deburring and coating material removal
• Used for composite and gelcoat refinement in assembly
• Can be used for edge rounding and de-flashing on machined parts
• Suitable for preparatory scuffing prior to topcoat application

What backing and attachment system does it use?

It uses a paper backing optimised for flexibility and durability and a Hookit attachment Interface for quick changes.

How does dust extraction performance affect workshop conditions?

The multi-hole extraction pattern is designed to remove most airborne and particulate dust when paired with extraction pads, improving shop cleanliness and reducing operator exposure.

Which grit and pack options are available for fine finishing?

A fine 1000 grit grade is offered within a comprehensive grade range extending from coarse through to 1000+, with bulk packaging available at 250 discs per pack.

What rotational speed limits should be observed?

The disc is rated for safe operation up to 12,000 r/min on compatible high-speed tools

users should match tool speed to this limit.

Which materials show best results with this abrasive?

It performs well on metals, paint-coated panels, composites and various woods, providing consistent finish and reduced rework in workshop environments.
