3M 7000121012 Hook Loop Disc 5 in Silicon Carbide Ultra Fine

Product Description

The 3M 7000121012 is a 5-inch hook and loop abrasive disc designed for surface finishing and preparation work. Built with a non-woven construction and silicon carbide abrasive material in an ultra fine grade, this disc delivers consistent scratch patterns and controlled material removal on a variety of substrates. The hook and loop attachment system allows for fast disc changes without tools, reducing downtime during repetitive finishing operations. It is commonly used by trade professionals and industrial finishing technicians who need reliable abrasive performance in light surface conditioning, blending, and deburring applications.

This disc is suited for use in maintenance, repair, and finishing environments where a controlled, ultra fine scratch pattern is required. It performs on metals, plastics, composites, and painted surfaces. The non-woven structure allows the disc to conform to contoured surfaces and resist loading, making it effective for finishing passes before coating or inspection. Typical applications include weld blending, surface conditioning between coats, and light deburring on fabricated parts.

Key Features

• 5-inch diameter with hook and loop backing for tool-free disc changes
• Silicon carbide abrasive material for consistent cut on hard surfaces
• Ultra fine grade for controlled finishing and minimal surface disruption
• Non-woven construction resists loading and conforms to curved surfaces
• Lightweight at 0.02 pounds per disc, reducing operator fatigue during extended use

Compatibility

Designed as an OEM-style replacement and standard fitment for 5-inch hook and loop random orbital sanders and finishing tools that accept non-woven abrasive discs.

Installation Notes

Attach to any compatible 5-inch hook and loop backing pad before powering the tool. Ensure the backing pad surface is clean and free of debris before mounting to maintain secure disc adhesion. Inspect the disc for tears or excessive wear before each use. Follow tool manufacturer guidelines and applicable workplace safety standards when operating powered abrasive equipment.
