Metabo 629423000 Flap Disc 60 Grit 6 Inch Type 29

Product Description

The METABO 629423000 is a Type 29 flap disc engineered for aggressive material removal on steel and stainless steel surfaces. Part of the Flapper Plus series, it uses a zirconia alumina abrasive bonded to fiberglass-backed flaps, delivering consistent cut rate and cool grinding action throughout the disc life. Rated at 10,200 RPM, the 6-inch disc mounts via a 7/8-inch arbor hole and is suited for use on angle grinders in fabrication, weld blending, and surface prep applications. The 60-grit coarse grade removes material quickly while still leaving a workable surface finish. Metalworkers and fabricators reach for this disc when speed of stock removal matters.

This disc is designed for use on steel and stainless steel in both shop and field environments. Typical applications include weld seam grinding, slag removal, deburring, and edge blending on structural steel, pipe, sheet metal, and fabricated components. The conical Type 29 profile allows greater surface contact at a low angle, making it well suited for flat and contour work on large workpieces. It is commonly used by welders, pipefitters, ironworkers, and metal fabricators.

Key Features

• Type 29 conical profile for increased surface contact and aggressive grinding at low angles
• 60-grit zirconia alumina abrasive provides fast, coarse stock removal on ferrous metals
• Fiberglass backing resists flex fatigue and supports the disc under lateral load
• Rated to 10,200 RPM for compatibility with standard 6-inch angle grinders
• 7/8-inch arbor hole fits common grinder spindle configurations
• Suitable for steel and stainless steel material applications

Compatibility

Designed for use on steel and stainless steel with standard 6-inch angle grinders equipped with a 7/8-inch arbor spindle.

Installation Notes

Installation and disc changes must be performed with the grinder unplugged or the power source locked out. Verify that the grinder's rated free-speed equals or exceeds the disc's 10,200 RPM maximum before mounting. Use the correct flange and locking nut for the arbor size, and inspect the disc for cracks or damage before each use. Always wear appropriate PPE including a face shield, and ensure workholding is secure before grinding.
