The NORTON 66252843789 is a Type 27 depressed center grinding wheel designed for aggressive material removal on metal surfaces. Measuring 6 inches in diameter and 1/4 inch thick, it uses a 24-grit coarse aluminum oxide abrasive bonded with a resinoid bond for durability under heavy grinding loads. The wheel mounts via a 5/8-11 threaded hub and is rated to a maximum of 13,580 RPM. It is suited for use with standard angle grinders and is a go-to choice for fabricators, ironworkers, pipefitters, and maintenance welders who need a reliable, fast-cutting grinding wheel.
This wheel is applicable to general metal grinding tasks including weld blending, surface preparation, and stock removal on steel and ferrous metals. The Type 27 depressed-center profile positions the abrasive face at a slight angle to the workpiece, allowing effective edge and flat-surface grinding. It is commonly used in fabrication shops, structural steel work, and field welding applications where consistent material removal and wheel durability are priorities.
Designed as a direct-mount replacement for Type 27 depressed center grinding wheels using a 5/8-11 threaded arbor, compatible with standard angle grinders accepting 6-inch Type 27 wheels.
Installation should be performed by a qualified operator following all applicable ANSI B7.1 safety standards for abrasive wheel use. Always power down and unplug the angle grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before each use and never exceed the rated maximum RPM of the grinder or the wheel, whichever is lower. Appropriate PPE including face shield, gloves, and hearing protection is required during operation.
