3M 7100105006 Flap Disc 7 Inch 40 Grit Right Angle

Product Description

The 3M 7100105006 is a 7-inch Type 29 right-angle flap disc engineered for medium to high-pressure grinding and finishing on metal surfaces. Built with 3M Precision-Shaped Grain bonded to a durable polyester backing, it delivers a fast, consistent cut rate throughout the life of the disc. At 40 grit, it is suited for aggressive material removal while still producing an acceptable surface finish. Licensed tradespeople and fabricators in welding, pipefitting, and metal fabrication regularly specify this disc for demanding tasks where both cut speed and finish quality matter.

This flap disc is designed for aggressive grinding applications including beveling, weld removal, and edge deburring on a variety of metals. The Type 29 angle geometry makes it well suited for work on flat and contoured surfaces with a right-angle grinder. It performs on mild steel, stainless steel, and other common structural metals encountered in fabrication shops, job sites, and maintenance environments.

Key Features

• 3M Precision-Shaped Grain provides an exceptionally fast cut rate for increased productivity
• Durable polyester backing withstands high unit pressure without delaminating
• Individual flaps break down progressively, exposing fresh abrasive mineral throughout disc life
• Lower risk of gouging compared to fiber discs and bonded grinding wheels
• Suited for applications where a smooth finish is required after material removal
• 40 grit aggressiveness handles beveling, weld removal, and deburring in a single disc

Compatibility

Designed for use with standard 7-inch right-angle grinders accepting a Type 29 flap disc configuration. Verify arbor size and grinder RPM rating against disc specifications before mounting.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety. Power down and unplug or lock out the grinder before mounting or removing the disc. Confirm the grinder's maximum RPM rating meets or exceeds the disc's rated speed before operation. Inspect the disc for damage before each use and follow ANSI B7.1 and applicable OSHA standards for abrasive wheel handling.
