3M 7100104887 Flap Disc 7 Inch 40 Grit Right Angle

Product Description

The 3M 7100104887 is the Cubitron II 969F flap disc, a 7-inch, 40-grit abrasive tool designed for medium to high-pressure grinding applications on metal. Built with 3M Precision-Shaped Grain bonded to a durable polyester backing, this disc delivers a fast, consistent cut rate throughout its service life. As individual flaps wear down, fresh mineral is continuously exposed, maintaining cutting efficiency from start to finish. It is well suited for trades and fabrication shops where aggressive material removal and a controlled surface finish are both required in the same operation.

The 969F flap disc is used in applications such as beveling, weld removal, and edge deburring on a variety of metals. Its right-angle configuration makes it compatible with standard right-angle grinders. The disc is engineered to reduce the risk of gouging compared to fiber discs and bonded wheels, making it a practical choice when surface finish quality matters alongside material removal rate. It is commonly specified in structural steel fabrication, pipe fitting, and metal finishing work.

Key Features

• 3M Precision-Shaped Grain provides an exceptionally fast cut rate for aggressive grinding tasks
• Durable polyester backing withstands high unit pressure without delaminating
• Individual flaps break down progressively, exposing fresh abrasive for consistent performance over disc life
• Lower risk of gouging compared to fiber discs and bonded abrasive wheels
• Suitable for applications where both stock removal speed and finish quality are priorities
• Right-angle disc profile for use with standard angle grinders

Compatibility

Designed for use with right-angle grinders accepting 7-inch flap discs. Suitable for grinding and finishing on a variety of metals including steel and stainless steel.

Installation Notes

Flap disc installation and operation should be performed by qualified personnel following grinder manufacturer guidelines and applicable ANSI safety standards for abrasive products. Verify the grinder's maximum RPM rating meets or exceeds the disc's rated speed before mounting. Inspect the disc for damage before each use and never use a disc that shows signs of delamination or cracking. Always use the appropriate guard and personal protective equipment including eye and face protection during operation.
