3M 7100049201 Cubitron Ii 967A 5 Inch 60 Grit Flap Disc

Product Description

The 3M 7100049201 is a Type 29 right-angle flap disc built around 3M Precision-Shaped Grain abrasive technology. At 5 inches in diameter and 60 grit, it delivers a fast, consistent cut rate throughout the life of the disc. Individual flaps break down progressively, continuously exposing fresh mineral so cut performance does not degrade as the disc wears. The poly-cotton backing provides controlled, even wear under medium unit pressure, making it well-suited for weld leveling, light deburring, and surface preparation ahead of paint or coating application.

This disc is designed for medium-pressure grinding applications on flat and contoured surfaces. It performs reliably on mild steel and stainless steel, including fabrication environments where finish quality and gouge resistance matter. Typical use cases include weld bead leveling, seam blending, and pre-paint surface prep in light industrial, metal fab shop, and field fabrication settings. Its reduced gouging tendency compared to fiber discs and bonded wheels makes it a practical choice where surface integrity is a priority.

Installation Notes

Flap discs of this type are mounted and serviced by metalworkers, fabricators, and maintenance technicians using standard right-angle grinders. Confirm the grinder arbor size and maximum RPM rating are compatible before mounting. Always power down and disconnect the grinder from its power source before changing discs. Inspect the disc for damage before each use and do not exceed the rated operating speed marked on the disc.
