3M 7100284210 Hook Loop Disc 80 Grit 5 Inch Ceramic

Product Description

The 3M 7100284210 is a 5-inch hook-and-loop abrasive disc designed for surface preparation, stock removal, and finish work on a range of substrates. Built on a J-weight cloth backing, this disc delivers flexibility and conformability on contoured surfaces. The ceramic abrasive grain operates at up to 12,000 RPM and is rated at 80 grit, placing it in the medium-to-fine grade range for controlled material removal and smooth finish results. It attaches via a hook-and-loop fastening system for fast disc changes without tools. Fabricators, metal finishers, woodworkers, and general trade contractors install this disc on compatible random orbital and disc sanders.

This disc is suited for shop and field use where consistent finish quality is required on metal, wood, or composite surfaces. The ceramic abrasive material provides durability and cut rate suitable for production environments as well as single-trade service work. The 5-inch diameter fits standard 5-inch hook-and-loop backup pads commonly used on random orbital sanders. Sold individually, it is appropriate for targeted replacement or low-volume use where full sleeve quantities are not needed.

Installation Notes

Mount only on a backup pad that matches the 5-inch disc diameter and uses a hook-and-loop fastening interface. Confirm the sander's maximum RPM rating does not exceed 12,000 RPM before use. Inspect the disc for tears or delamination before mounting. Eye protection and appropriate respiratory protection should be worn during grinding and sanding operations per applicable safety standards.
