3M 3M Cubitron II Hookit Paper Discs 732U No Hole Series Grinding Disc, 152.4mm Disc Diameter, 600 Grit size - 7100335485

This grinding disc is a resin-bonded, hook-and-loop paper abrasive designed for industrial sanding and finishing tasks. It combines precision-shaped abrasive mineral with a paper backing to deliver Rapid material removal and a consistent surface finish across metals, coated surfaces, wood and composites, and is suitable for use with powered and hand sanding tools.

Features & Benefits

• Precision-shaped grain improves cut rate and reduces heat build-up
• Up to 12,000 rpm maximum safe operating speed for high-speed tasks
• Anti-load coating reduces clogging and maintains cut performance
• Hookit no-hole attachment enables fast disc changes on pads
• C-weight paper backing balances flexibility with job durability

Applications

• Suitable for Rapid metal surface dimensioning and stock removal
• Ideal for preparation and scuffing prior to topcoat application
• Used for paint-coated surface and coating refinement work
• Can be used for de-flashing and edge rounding on composites
• Suitable for sanding in electronics chassis and mechanical assemblies

What backing and attachment system does it use for ease of use?

It uses a paper backing with Hookit hook-and-loop attachment for quick on/off with compatible backing pads.

How does the abrasive resist loading when working on paint or coatings?

An anti-load coating is applied to the precision-shaped grain to reduce material build-up and sustain cutting efficiency.

What abrasive grades are available for finer finishing needs?

The grade provided here is 600 grit aimed at fine finishing

the product family includes a wide range of coarser and finer grades.

Is the disc compatible with dust extraction systems?

The product is offered in configurations compatible with proprietary multi-hole extraction patterns to support improved dust control when used with extraction-capable systems.

How does the abrasive perform on mixed-material assemblies?

The shaped mineral formulation slices through varying substrates, enabling a consistent finish and fewer rogue scratches across metals, composites and wood.
