3M 7000119472 Flap Disc 40 Grit 4.5 in Type 29

Product Description

The 3M 7000119472 is a Type 29 coated abrasive flap disc engineered for high-pressure metalworking applications. It uses alumina zirconia mineral combined with a grinding aid to deliver faster cutting action than standard aluminum oxide abrasives across steel, stainless, and other metal types. Flaps are backed with heavyweight polyester for durability under sustained pressure. At a maximum speed of 13,300 RPM and a 40-grit designation, this disc handles aggressive stock removal while simultaneously blending the surface, reducing the need for a separate finishing step. Licensed metalworking tradespeople and fabricators are the primary installers and users of this product.

This flap disc is sized at 4.5 inches in diameter and is suited for weld removal, sharp-edge work, beveling, and general heavy-duty metal grinding on fabrication and construction job sites. The Type 29 conical profile increases surface contact on flat and contoured workpieces. The quick-change design allows for faster disc swaps, minimizing downtime during production or field work. It is sold individually and is appropriate for use in residential metal fabrication shops as well as commercial and industrial settings.

Compatibility

Designed for use with angle grinders accepting 4.5-inch Type 29 flap discs rated at or above 13,300 RPM. Suitable for grinding and blending on steel, stainless steel, and other metals.

Installation Notes

Mount only on angle grinders rated at or above the disc maximum speed of 13,300 RPM. Ensure the grinder is fully powered off and unplugged before changing discs. Verify that the backing flange and retaining nut are compatible with Type 29 disc geometry before securing. Always wear appropriate PPE including face shield and gloves during operation.
