Bullard 36726 Flap Disc Type 29 7 Inch 60 Grit Zirconium

Product Description

The BULLARD 36726 is a Type 29 zirconium flap disc designed for metal grinding and finishing applications. Built on the Tornado-Z standard profile, this disc features overlapping abrasive flaps bonded to a fiberglass backing plate that presents fresh cutting grain as the disc wears. The 7-inch diameter disc fits a 7/8-inch arbor and is rated to a maximum of 8,500 RPM. The 60-grit zirconium alumina construction provides an aggressive cut rate suited for stock removal as well as intermediate finishing passes on ferrous and non-ferrous metal surfaces.

This flap disc is used in fabrication shops, welding operations, and general metalworking environments where operators need to remove weld seams, deburr edges, or blend surface profiles in a single tool pass. The Type 29 conical profile concentrates grinding pressure at the disc edge, making it well suited for work on flat and contoured metal surfaces. It is sold and packaged in a box quantity of 10 discs, supporting both individual technicians and production-level workflows.
