3M 7100067094 Hook Loop Disc 180 Grit 6 in Ceramic

Product Description

The 3M 7100067094 is a 6-inch hook and loop abrasive disc designed for surface finishing, blending, and stock removal on metal, wood, and composite substrates. Part of the 3M 732U series, this disc uses a ceramic abrasive grain bonded to a coated backing in a fine 180-grit configuration. Ceramic abrasive cuts faster and lasts longer than aluminum oxide on hard materials, making it a reliable choice for production sanding and finishing applications. The hook and loop attachment system allows quick disc changes on compatible random orbital and disc sanders, reducing downtime during multi-step finishing sequences. At 0.01 pounds, the disc adds minimal weight to the tool.

This disc suits residential and light commercial finishing work where a fine surface profile is required before priming, painting, or coating. Typical applications include metal prep on ductwork and structural components, wood surface finishing in millwork or cabinet shops, and composite panel blending. The 180-grit fine grade removes minor scratches and sanding marks left by coarser grits and prepares surfaces for final finish coats. It is used by HVAC fabricators, finish carpenters, metalworkers, and general tradespeople who require a consistent fine scratch pattern across a range of substrates.

Key Features

• Ceramic abrasive grain for fast cut rate and extended disc life on hard materials
• 180 grit fine grade for surface prep, blending, and pre-finish sanding
• 6-inch diameter fits standard hook and loop random orbital and disc sanders
• Coated abrasive construction for consistent grain orientation and uniform scratch pattern
• Hook and loop backing enables fast disc swaps without tools or adhesives
• 732U series construction balances flexibility and durability across metal and wood surfaces

Compatibility

Designed for use with 6-inch hook and loop random orbital sanders and disc sanders that accept standard hook and loop abrasive discs.

Installation Notes

Attach the disc to a clean, dry hook and loop backup pad before use. Inspect the pad face for debris or worn hooks that could cause the disc to release during operation. Do not exceed the maximum RPM rating of the sander being used. Wear appropriate eye protection and respiratory protection when sanding metal or composite materials that may produce fine particulate.
