4-1/2" x 7/8" (115x22mm) T27 S90 Zirconia Flap Disc - 10Pcs/Box

4-1/2" x 7/8" T27 (Flat Face) S90 Zirconia Flap Discs are a versatile product that can be used from aggressive stock removal to surface blending. The layered construction of abrasive flaps on this flap disc will continually expose new grains for longer life and finer finish compared to resin fiber discs. It can be used for heavy material removal on all types of metals.

T27 (flat face) discs are perfect for grinding down items that are not flat surfaces (like fence posts, gates, and risers etc). 

Zirconia grains have a self-sharpening property and stand up to higher heat and pressure than Aluminum Oxide (A/O), thus making Zirconia the go-to option, providing excellent stock removal that gives you more bang for your buck.
