3M 7100104936 Flap Disc 5 Inch 60 Grit Right Angle

Product Description

The 3M 7100104936 is a Type 29 right-angle flap disc engineered for medium to high-pressure grinding and finishing on metal surfaces. Built around 3M Precision-Shaped Grain bonded to a durable polyester backing, this 5-inch, 60-grit disc delivers a fast, consistent cut rate from first use to last. As individual flaps wear, they break down to expose fresh abrasive mineral, maintaining aggressive stock removal throughout the disc life. Fabricators, welders, and metal finishing trades rely on this disc for beveling, weld removal, and edge deburring where both speed and surface finish matter.

This flap disc is suited for residential and commercial fabrication, structural steel work, and metal finishing environments. The right-angle Type 29 profile keeps the abrasive face at a working angle that increases surface contact on flat and contoured workpieces. The polyester backing holds up under sustained high unit pressure without delaminating, making it appropriate for continuous production grinding as well as intermittent service work. Applications include weld bead removal, beveling prior to welding, edge deburring, and blending on ferrous and non-ferrous metals.

Key Features

• 3M Precision-Shaped Grain delivers an exceptionally fast cut rate for aggressive stock removal
• Durable polyester backing withstands high unit pressure without breakdown
• Self-renewing flap construction exposes fresh mineral as the disc wears for a consistent cut throughout disc life
• Lower gouging risk compared to fiber discs and bonded grinding wheels
• Suitable for applications where surface finish quality is a priority alongside material removal
• 5-inch diameter, 60 grit — suited for medium-aggressive beveling, weld removal, and deburring

Compatibility

Designed for use with 5-inch right-angle grinders accepting standard Type 29 flap discs. Confirm spindle thread and guard clearance before installation.

Installation Notes

Installation and use should be performed by qualified personnel familiar with angle grinder safety practices. Inspect the disc for damage before mounting and never operate above the maximum RPM rated for the disc. Ensure the grinder is disconnected from power before mounting or removing the disc. Always use the appropriate guard and personal protective equipment including eye and face protection.
