3M 732U Precision Shaped Grain, 152.4 mm Resin, 320+ Grade, 320 Grit 250 Per Pack

This grinding disc is a resin-bonded abrasive designed for industrial material removal and finishing in workshop environments. It uses precision-shaped grain technology to deliver Rapid cutting and consistent surface results, while being compatible with extraction systems and hook-and-loop attachment for efficient changeover.

• Cuts up to 2x Faster delivering higher throughput
• Anti-load coating reduces clogging and downtime
• Precision-shaped grain produces consistent surface quality
• Compatible with multi-hole extraction patterns for cleaner workspaces
• C-weight paper backing balances flexibility with durability

• Suitable for dimensioning metal components in assembly lines
• Ideal for scuffing and prep prior to topcoat application
• Used for coating removal on paint-coated parts
• Can be used for trimming composites and gelcoat components
• Suitable for light-duty material removal on wood parts

It features a C-weight paper backing and is compatible with a Hookit™ style hook-and-loop attachment for quick disc swaps.

The disc is available with a multi-hole Xtract™ pattern which improves dust removal and reduces loading during sanding operations.

It is suitable for metals, paint coatings, composites, gelcoat and different types of wood encountered in industrial workflows.

The precision-shaped grain and anti-load coating extend service life, reducing the frequency of disc changes versus conventional aluminium oxide abrasives.
