Bullard 37626 Flap Disc Type 29 Zirconium 4.5 in 60 Grit

Product Description

The BULLARD 37626 is a zirconium flap disc designed for aggressive metal grinding and finishing applications. Built to a Type 29 standard profile, this disc delivers a consistent cut on ferrous and non-ferrous metals. The Tornado-Z construction uses overlapping zirconium abrasive flaps bonded to a fiberglass backing plate, producing a self-sharpening action that extends disc life compared to standard aluminum oxide. At 60 grit, it removes material quickly while leaving a surface ready for follow-on finishing work. The 5/8-11 threaded arbor fits most standard angle grinders used in fabrication, maintenance, and metalworking trades.

This disc is suited for residential and commercial metalworking tasks including weld blending, deburring, edge preparation, and surface conditioning on structural steel, pipe, plate, and sheet metal. The Type 29 angled flap configuration increases surface contact on flat and contoured workpieces, making it a practical choice for fabricators and maintenance technicians who alternate between flat grinding and edge work on the same job.
