Bullard 36626 Flap Disc Type 29 4.5 in 60 Grit Metal Grinding

Product Description

The BULLARD 36626 is a zirconium flap disc designed for metal grinding and finishing applications. Built to a Type 29 standard-profile geometry, the angled disc face delivers aggressive material removal while allowing a broader contact area on flat and contoured surfaces. At 60 grit, it sits in the coarse-to-medium range, making it well-suited for weld blending, scale removal, and surface prep before coating. The disc measures 4.5 inches in diameter with a 7/8-inch arbor hole and is rated to a maximum of 13,300 RPM. A licensed angle grinder operator or metal fabricator handles installation and use.

This flap disc is intended for use on metal substrates in both fabrication shop and field environments. Typical applications include weld seam blending, deburring, and surface conditioning on structural steel, pipe, and sheet metal. The zirconium abrasive grain maintains cutting efficiency under heat and pressure, extending disc life compared to standard aluminum oxide flap discs. It is sold in boxes of 10, making it practical for stocking on a job site or in a shop inventory.
