Metabo 629422000 Flap Disc 40 Grit 6 Inch Type 29

Product Description

The METABO 629422000 is a Type 29 conical flap disc designed for aggressive material removal on steel and stainless steel. Part of the Flapper Plus series, it uses a ceramic zirconia alumina abrasive bonded to fiberglass-backed flaps for durability under high heat and load. At 40 grit coarse grade, it cuts fast and runs at a maximum of 10,200 RPM. The 7/8 inch arbor hole mounts directly to standard angle grinders. At 6 inches in diameter, this disc suits both production grinding and weld blending tasks handled by metalworkers and fabricators.

This flap disc is used in metal fabrication shops, structural steel work, and field welding applications. The Type 29 angled design increases the surface contact area compared to a flat Type 27 disc, making it effective for blending, deburring, and material removal on flat and contoured steel surfaces. Compatible material applications include mild steels and stainless steel. The coarse 40 grit rating is appropriate for removing heavy scale, weld splatter, and surface oxidation.

Key Features

• Type 29 conical geometry for increased contact on flat and curved surfaces
• Ceramic zirconia alumina abrasive delivers fast stock removal and extended disc life
• 40 grit coarse grade suited for weld blending, scale removal, and surface prep on steel
• Fiberglass backing provides structural support at elevated grinding speeds
• 10,200 RPM maximum rated speed for use on standard 6 inch angle grinders
• 7/8 inch arbor hole fits common angle grinder spindles without adapters

Compatibility

Designed for use on mild steels and stainless steel. Fits angle grinders with a 7/8 inch arbor and a 6 inch disc capacity rated to 10,200 RPM or higher.

Installation Notes

Installation and disc changes must be performed with the grinder unplugged or the power source locked out. Confirm that the grinder spindle speed does not exceed the 10,200 RPM maximum disc rating before use. A licensed or experienced metalworker should inspect the disc for cracks or damage before mounting. Always use the correct arbor flange hardware and follow ANSI B7.1 safety requirements for abrasive wheel mounting and guarding.
