3M 7100104599 Flap Disc 7 Inch 80 Grit Right Angle

Product Description

The 3M 7100104599 is a Type 29 right-angle flap disc designed for aggressive metalworking tasks including beveling, weld removal, and edge deburring. Built with 3M Precision-Shaped Grain bonded to a durable polyester backing, this 7-inch, 80-grit disc delivers a fast, consistent cut rate throughout its full service life. As individual flaps wear down, fresh abrasive mineral is exposed, maintaining cutting performance without requiring operator adjustment. The polyester backing withstands high unit pressure, making this disc well suited for demanding production grinding where both cut speed and surface finish matter.

This flap disc is used in fabrication shops, welding environments, and structural steel applications where medium to high grinding pressure is applied. It is appropriate for use on a variety of metals including carbon steel, stainless steel, and aluminum. The right-angle geometry suits standard 7-inch angle grinders used by welders, pipefitters, ironworkers, and metal fabricators. The disc profile reduces the risk of gouging compared to fiber discs and bonded grinding wheels, making it a practical choice for work where surface finish quality is a factor alongside material removal rate.

Key Features

• Durable polyester backing withstands high unit pressure in aggressive grinding applications
• Flap construction exposes fresh mineral as the disc wears, delivering consistent cut rate for the disc's full life
• Lower risk of gouging compared to fiber discs and bonded wheels
• Suited for applications where surface finish is important alongside aggressive material removal
• Designed for beveling, weld removal, and edge deburring on a variety of metals

Compatibility

Designed for use with standard 7-inch right-angle grinders. Suitable for grinding and finishing on carbon steel, stainless steel, aluminum, and other metals in fabrication and welding applications.

Installation Notes

This disc is installed and serviced by welders, metal fabricators, and ironworkers using standard 7-inch angle grinders. Always ensure the grinder is powered off and unplugged before mounting or removing the disc. Verify that the grinder's rated RPM meets or exceeds the disc's maximum rated speed before use. Inspect the disc for damage before each use and never operate a disc that shows signs of cracking or excessive wear.
