Metabo 629480000 Flap Disc 36 Grit 4.5 in Type 27

Product Description

The METABO 629480000 is a Type 27 zirconia alumina flap disc designed for aggressive material removal on metal surfaces. Part of the Flapper Plus series, it features a fiberglass backing plate that provides rigidity and support during grinding and blending operations. The 36-grit coarse abrasive delivers fast stock removal on steel, stainless steel, and heat-sensitive materials where controlling heat buildup is a priority. Rated to 13,300 RPM, this disc is sized at 4.5 inches in diameter with a 7/8-inch arbor hole for compatibility with standard angle grinders used in fabrication, welding prep, and surface conditioning work.

This flap disc is suited for metal fabrication shops, welding environments, and maintenance applications where coarse grinding is required on steel or stainless steel. The Type 27 flat profile is appropriate for flat surface work and applications requiring consistent contact across the disc face. It is installed and operated by metalworkers, welders, pipefitters, and maintenance technicians working with angle grinders in both shop and field settings. The zirconia alumina abrasive is particularly effective on heat-sensitive base materials where reducing thermal input to the workpiece is important.

Compatibility

Designed for use with 4.5-inch angle grinders equipped with a 7/8-inch arbor. Rated for applications on steel, stainless steel, and heat-sensitive materials as specified by the manufacturer.

Installation Notes

Installation and operation should be performed by qualified personnel familiar with angle grinder safety practices. Always confirm the grinder's no-load RPM does not exceed the disc's 13,300 RPM maximum rating before mounting. Inspect the disc for cracks or damage before each use and ensure the backing plate and guard are properly secured. Use appropriate PPE including eye protection and gloves when operating abrasive grinding equipment.
