3M 7100007032 Surface Conditioning Disc 4 Inches Roloc Tr

Product Description

The 3M 7100007032 is a non-woven abrasive surface conditioning disc designed for cleaning, finishing, blending, and deburring on metal and similar surfaces. Measuring 4 inches in diameter with a Very Fine (VFN) grade and A-weight construction, this disc mounts via the Roloc TR threaded attachment system, which allows fast one-handed disc changes on compatible backup holders. The disc is intended for use with angle grinders and die grinders in fabrication, welding prep, and surface finishing work. Technicians and fabricators rely on this format for consistent surface preparation without loading or gouging the base material.

This disc suits residential and commercial metalworking applications including weld blending, rust and scale removal, edge deburring, and pre-coating surface prep. The Very Fine grade makes it appropriate for finishing passes and light cleaning rather than aggressive stock removal. It is commonly used in HVAC fabrication shops, plumbing rough-in work involving copper or galvanized steel, and general mechanical trades where controlled surface conditioning is required before assembly or coating.

Key Features

• Non-woven abrasive construction resists loading and conforms to irregular surfaces
• Very Fine (VFN) grade suited for finishing, blending, and light cleaning passes
• 4-inch diameter provides consistent coverage on flat and contoured workpieces
• Roloc TR threaded hub enables fast one-handed disc changes without tools
• A-weight backing balances flexibility and durability for general-purpose conditioning tasks

Compatibility

Designed for use with Roloc TR threaded backup pads and holders compatible with the TR attachment system. Verify that the backup pad is rated for the disc diameter and the grinder speed before use.

Installation Notes

Installation is performed by threading the disc onto a Roloc TR-compatible backup pad until secure. Power down and disconnect the grinder or die grinder from its power source before mounting or removing discs. Always confirm the tool RPM rating meets or exceeds the disc speed rating, and wear appropriate PPE including eye protection and gloves during operation.
