3M 7100145461 Cubitron Ii 775L Film Disc 320 Grit 6 Inch

Product Description

The 3M 7100145461 is a coated abrasive film disc from the Cubitron II 775L series, engineered around 3M Precision Shaped Grain technology. The triangular ceramic mineral is designed to slice through material rather than plow or gouge like conventional abrasives, delivering cut rates up to 2x faster and service life up to 6x longer than standard abrasive discs. At 6 inches in diameter and 320 grit, this disc is built for controlled stock removal and finishing passes. The film backing adds tear resistance and holds its edge longer than paper-backed alternatives. Licensed HVAC techs, metal fabricators, and finishing tradespeople will recognize this as a high-cycle production disc.

This disc is suited for stock removal applications across a wide range of substrates including ferrous and non-ferrous metals, composites, and painted surfaces. The 320 grit designation makes it appropriate for finish sanding and surface prep work where a smooth, consistent scratch pattern is required before coating or inspection. The hook and loop attachment system allows fast disc swaps on compatible random orbital and disc sanders without tools, reducing downtime during production or service work.

Key Features

• 3M Precision Shaped Ceramic Grain slices material rather than gouging, extending disc life up to 6x vs conventional abrasives
• Cuts up to 2x faster than conventional coated abrasive discs
• Film backing provides greater tear resistance and improved edge retention over paper backing
• Hook and loop attachment enables tool-free disc changes on compatible sanders
• 320 grit for controlled stock removal and pre-coating surface preparation
• 6 inch diameter fits standard random orbital and disc sander pads

Compatibility

Designed for use with 6 inch hook and loop sanding pads on random orbital sanders and disc sanders that accept hook and loop backed discs.

Installation Notes

Ensure the sander backing pad is clean and free of debris before attaching the disc, as contamination under the disc can cause uneven wear or premature failure. Power down the sander completely before changing discs. Inspect the hook and loop backing pad regularly for worn hooks that can reduce holding force and cause disc slippage during operation. Follow applicable workplace safety standards for respiratory protection when sanding metals, composites, or coated surfaces.
