Norton 77696090175 Flap Disc 36 Grit Zirconia Alumina Type 27

Product Description

The NORTON 77696090175 is a Type 27 coated flap disc designed for aggressive material removal on metal and fabricated surfaces. Built with zirconia alumina abrasive at a coarse 36 grit, it delivers fast stock removal on welds, scale, and rough surface profiles. The disc measures 2 inches in diameter and features a fiberglass backing for rigidity and durability under load. A Quick-Change Type S attachment allows for rapid mounting without a wrench. Rated to 30,000 RPM, it is suited for use with compatible high-speed rotary tools. Fabricators, welders, and metalworkers are the primary installers of this disc.

This flap disc is used in metal fabrication, weld blending, and surface preparation applications where a coarse cut rate is needed. The Type 27 flat profile is appropriate for working on flat or moderately contoured surfaces. Its small 2-inch diameter makes it practical for tight access areas and detail grinding tasks in both shop and field environments. It ships in a minimum order quantity of 10 units, with individual package quantity of 1.
