Norton 66252842004 Type 27 Grinding Cutting Wheel 4in

Product Description

The NORTON 66252842004 is a Type 27 depressed center abrasive wheel engineered for light grinding and cutting on metal. Built on the NorZon Plus platform, this wheel features a recessed center hub design that allows a lower grinding angle, improving surface contact and operator control during use. At 4 inches in diameter with a 1/8-inch thickness and a 3/8-inch arbor bore, it is sized for small-to-medium angle grinders commonly used in fabrication and field service work. Metal trades professionals reach for this wheel when they need consistent stock removal without excessive heat buildup on thinner workpieces.

This wheel is suited for light grinding and cutting applications on metal surfaces in both shop and field environments. Typical use cases include weld cleanup, deburring, and light material removal on structural steel, pipe, and sheet metal. The Type 27 profile makes it a standard choice for work requiring a low-profile approach angle. It is sold individually but is available in case quantities of 25, making it practical for shops and service fleets that go through wheels at volume.
