3M 7100049203 Flap Disc 5 Inch 80 Grit Cubitron Ii 967A

Product Description

The 3M 7100049203 is a 5-inch, 80-grit right-angle flap disc from the Cubitron II 967A series, designed for medium-pressure grinding and surface preparation on flat and contoured workpieces. Built around 3M Precision-Shaped Grain, the disc cuts aggressively and maintains a consistent removal rate throughout its service life. Individual flaps break down progressively, exposing fresh abrasive mineral as the disc wears. This makes it well suited for weld leveling, light deburring, and surface prep before paint or coating. The disc is intended for use by fabricators, metalworkers, and maintenance professionals operating angle grinders.

This disc is engineered for medium-duty applications on mild steel and stainless steel. Typical use cases include weld removal, weld leveling, and surface preparation for paint or coating in both shop fabrication and field service environments. The 80-grit cut rate is appropriate for material removal tasks that require a controlled finish without deep gouging. Stainless steel fabricators benefit from the disc's reduced tendency to gouge compared to fiber discs and bonded wheels, making it easier to maintain surface finish quality and minimize rework.

Key Features

• 3M Precision-Shaped Grain delivers fast, consistent cutting throughout disc life
• Progressive flap breakdown exposes fresh mineral, maintaining cut rate as the disc wears
• Poly-cotton backing provides controlled, even wear under medium unit pressure
• Less gouging than fiber discs and bonded wheels, preserving surface finish on stainless steel
• Suited for flat and contoured surfaces in weld leveling and light deburring applications
• Right-angle disc configuration for use with standard angle grinders

Compatibility

Designed as an OEM-style replacement or direct-use abrasive flap disc for right-angle grinders accepting 5-inch disc accessories in medium-duty grinding and surface preparation applications.

Installation Notes

Installation of flap discs must be performed by qualified personnel familiar with angle grinder safety requirements. Verify that the grinder's maximum RPM rating meets or exceeds the disc's rated speed before mounting. Ensure the grinder is fully powered off and disconnected from its power source before changing discs. Always use the appropriate flange and backing hardware specified by the grinder manufacturer, and confirm the disc is securely seated before resuming operation.
