3M 7100104886 Cubitron Ii 969F Flap Disc 5 Inch 60 Grit

Product Description

The 3M 7100104886 is a Type 29 right-angle flap disc built for aggressive metal grinding, beveling, weld removal, and edge deburring. It uses 3M Precision-Shaped Grain bonded to a durable polyester backing, producing a fast, consistent cut rate throughout the life of the disc. At 5 inches in diameter and 60 grit, it is suited to medium-to-high-pressure applications where both stock removal speed and surface finish quality matter. As individual flaps wear down, fresh mineral is exposed, maintaining cut consistency without the need to change discs as frequently as with conventional abrasives. Licensed tradespeople and fabricators working on ferrous and non-ferrous metals are the primary installers.

This flap disc is designed for use with right-angle grinders in metal fabrication, structural steel work, pipe welding prep, and general metalworking environments. It performs well on carbon steel, stainless steel, and other common metals encountered in HVAC fabrication, plumbing rough-in metalwork, and industrial maintenance. Its geometry reduces the risk of gouging compared to fiber discs and bonded grinding wheels, making it a practical choice when surface finish is a factor alongside material removal rate.

Key Features

• 3M Precision-Shaped Grain delivers a fast, aggressive cut on a wide range of metals
• Polyester backing withstands high unit pressure for demanding grinding applications
• Individual flaps break down progressively, exposing fresh abrasive mineral for consistent cut life
• Lower gouging risk compared to fiber discs and bonded abrasive wheels
• Suited for beveling, weld removal, and edge deburring where finish quality matters
• Right-angle mounting geometry for use with standard angle grinders

Compatibility

Designed for use with right-angle grinders accepting 5-inch diameter flap discs. Suitable for grinding and finishing applications on ferrous and non-ferrous metals.

Installation Notes

Mounting and disc changes should be performed by qualified personnel following the grinder manufacturer's guard and speed rating requirements. Verify that the grinder's rated RPM meets or exceeds the disc's maximum RPM rating before use. Always power down and disconnect the grinder before mounting or removing the disc. Eye protection, gloves, and appropriate PPE are required per OSHA and ANSI B11 grinding safety guidelines.
