Bullard 37726 Type 29 Flap Disc 7 Inch 60 Grit Zirconia

Product Description

The BULLARD 37726 is a Type 29 zirconia flap disc designed for aggressive metal grinding and finishing on angle grinders. Built on a standard profile, the disc measures 7 inches in diameter with a 5/8-11 arbor thread, making it compatible with standard large-angle grinder spindles. The 60-grit zirconia abrasive provides a balance between material removal rate and surface finish, making this disc a practical choice for weld blending, deburring, and surface prep on steel and other metals. Maximum operating speed is 8,500 RPM. These discs are sold in boxes of 10.

This flap disc is suited for fabrication shops, structural steel work, and general metal finishing tasks where a durable, long-lasting abrasive is required. The Type 29 angled design allows increased surface contact on flat and contoured workpieces, which improves efficiency during grinding passes. Metalworkers, welders, and fabricators will find the 60-grit cut rate effective for removing mill scale, smoothing welds, and preparing surfaces before coating or inspection.

Installation Notes

Flap discs are installed and removed by metalworkers and fabricators using standard angle grinder tooling. Always verify the grinder's free-speed RPM does not exceed the disc's 8,500 RPM rating before mounting. Inspect the disc for damage before each use and discard any disc that shows cracking, delamination, or missing flaps. Follow applicable ANSI B7.1 safety standards for abrasive wheel use, including the use of appropriate eye and face protection.
