WALTER Surface Technologies - 4-1/2" Disc Diam, 5/8-11 Center Hole, Type 27 Ceramic Flap Disc - 13,300 Max RPM, Plastic Backing, Arbor Attaching System, Non-Woven

Non-Woven abrasives reduce undercutting and gouging of surfaces. They are frequently used in deburring, surface preparation and as a final finishing step.

Type 27 flap discs are less aggressive and are used primarily on flat surfaces for grinding a smoother finish.

Cooler cutting and more durable than natural aluminum based products, ceramic provides a sharp, high purity grain. Commonly used for precision grinding of steels, hard alloys and exotic materials.

Arbors require adapting nuts. They eliminates cross threading.
