Tru-Maxx - 40 Grit, 4-1/2" Disc Diam, 7/8" Center Hole, Compact Ceramic Flap Disc - 13,300 Max RPM, Fiberglass Backing, Arbor Attaching System, Coated

Coated abrasives can be used for most applications, from grinding to polishing. They consist of a thin layer of abrasive adhered to fiber, paper, cloth or rubber. Coated discs are normally used on angle grinders.

Compact discs are designed with a trimmable backing that exposes the grains during heavy-duty machining. These discs increase tool life and reduce the amount of equipment changes during an application. They are compressed and compacted at 4 degrees for edge strength.

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.
