3M 732U Series Grinding Disc, 127mm Diameter, 500 Grit - 7100335451

This grinding disc is a resin-bonded abrasive designed for industrial sanding and cutting tasks across metal, timber, composites and paint-coated surfaces. It is intended for use with hook-and-loop back-up pads and dust-extraction systems in workshop and production settings where high throughput and reduced rework are priorities.

Features & Benefits

• Precision-shaped grain delivers Faster cutting and cooler operation
• Anti-load coating reduces clogging and maintains cut rate
• Multi-hole compatibility improves dust extraction performance
• C-weight paper backing balances flexibility and durability
• Long life reduces disc changes and lowers operating cost

Applications

• Suitable for dimensioning composite panels and gelcoat trimming
• Ideal for scuffing and preparation prior to topcoat application
• Used for de-flashing and edge rounding on fabricated parts
• Can be used for coating removal and coating refinement on painted surfaces

What backing type supports multiple sanding methods?

The paper backing is C-weight, permitting both hand and powered tool use while retaining form for repeated jobs.

How does the abrasive minimise downtime in production?

The precision-shaped mineral Plus anti-load treatment extends usable life, so fewer disc swaps are required during continuous operations.

Which dust-control advantage does it provide?

When used with a compatible multi-hole extraction pad, the disc assists in removing particulate to reduce loading and improve workshop cleanliness.

What surfaces will the product handle without special preparation?

It performs on metals, various timbers, composites and paint-coated substrates, allowing direct sanding or cutting in mixed-material assemblies.
