3M 7100064174 Hook Loop Disc 5 in 150 Grit Ceramic

Product Description

The 3M 7100064174 is a 5-inch hook and loop abrasive disc engineered for coated abrasive grinding and finishing applications. Built on the 775L series platform, this disc uses a ceramic abrasive mineral bonded to a coated backing. Ceramic abrasives fracture during use to continuously expose fresh cutting edges, which extends disc life and maintains a consistent cut rate. At 150 grit, this disc falls in the fine grade range, making it well suited for surface preparation, blending, and finish sanding steps where scratch pattern control matters. Installers and fabricators working with metal, composite, or painted surfaces will find this grit level appropriate for pre-finish or intercoat prep work.

This disc is designed for use with 5-inch random orbital and orbital sanders equipped with hook and loop backing pads. It is commonly used in automotive body work, metal fabrication shops, HVAC sheet metal prep, and general contractor finishing tasks. The hook and loop attachment system allows fast disc changes without adhesive, which reduces downtime on the job. Fine grade ceramic abrasives at this diameter are a standard consumable in any shop performing repeated surface blending or coating prep cycles.

Key Features

• Ceramic abrasive mineral self-sharpens during use for extended disc life
• 150 grit fine grade for surface blending, finish prep, and scratch refinement
• Hook and loop backing for tool-free disc changes on compatible sanders
• Coated abrasive construction on 3M 775L series platform
• 5-inch diameter fits standard 5-inch hook and loop orbital sanding pads

Compatibility

Designed for use with 5-inch hook and loop random orbital or orbital sanders accepting standard 5-inch coated abrasive discs. No specific compatible model numbers were provided in the product data.

Installation Notes

Attach to a compatible hook and loop sanding pad by pressing the disc firmly onto the pad face before starting the tool. Ensure the sander backing pad is clean and free of debris that could prevent proper engagement. Inspect the disc before each use and discard any disc that shows tearing, excessive loading, or delamination. Personal protective equipment including eye protection and a dust mask rated for fine particulate is recommended during use.
