3M 7100049202 Cubitron Ii 967A Flap Disc 5 Inch 80 Grit

Product Description

The 3M 7100049202 is the Cubitron II 967A flap disc, a medium-duty abrasive tool engineered for right-angle grinder use. Built around 3M Precision-Shaped Grain, this 5-inch diameter, 80-grit disc delivers a fast, consistent cut rate that outlasts conventional ceramic and aluminum oxide flap discs. It is designed for metal fabrication professionals who need controlled material removal without gouging or irregular surface profiles. The poly-cotton backing promotes even wear across the disc face, keeping cut rate stable from first use through the life of the disc.

The 967A flap disc is well suited for medium-pressure applications on both flat and contoured metal surfaces. Common use cases include weld removal and weld leveling, light deburring, and surface preparation before painting or coating. It performs reliably on mild steel and is a proven choice for stainless steel fabrication where maintaining a clean surface finish and avoiding deep gouges is critical. Metal fabricators, weld shops, and maintenance grinding applications are the primary environments for this disc.

Key Features

• 3M Precision-Shaped Grain provides fast cutting action and extended disc life compared to conventional abrasives
• Individual flaps break down progressively, continuously exposing fresh mineral for a consistent cut rate
• Poly-cotton backing delivers controlled, even wear under medium unit pressure
• Less gouging than fiber discs and bonded grinding wheels, reducing rework on finished surfaces
• Effective on mild steel and stainless steel fabrication applications
• Right-angle grinder compatible geometry for weld leveling and surface prep

Compatibility

Designed for use on right-angle grinders accepting 5-inch diameter flap discs. Suitable for mild steel and stainless steel workpieces in medium-pressure grinding and surface preparation applications.

Installation Notes

Installation and disc changes must be performed with the grinder powered off and unplugged or locked out per applicable safety procedures. Verify the grinder spindle speed rating meets or exceeds the disc maximum RPM before mounting. Inspect the disc for damage before each use and discard any disc with torn flaps or a compromised hub. Appropriate PPE including eye protection and gloves is required during grinding operations.
