Norton 66252938855 Type 27 Grinding Wheel 7 Inches

Product Description

The NORTON 66252938855 is a Type 27 depressed center grinding wheel designed for use with angle grinders in heavy-duty material removal applications. Built with a ceramic alumina abrasive and a resinoid bond, this 7-inch wheel delivers aggressive stock removal and consistent cut rates across a wide range of metalworking tasks. It measures 7 inches in diameter with a 1/8-inch thickness and accepts the standard 5/8-11 threaded spindle found on most professional-grade angle grinders. The wheel is rated to a maximum of 8,600 RPM, making it appropriate for sustained grinding work where heat resistance and abrasive longevity matter.

This wheel is suited for professional metalworking environments including fabrication shops, structural steel work, weld grinding, and surface prep on ferrous and hard metals. The ceramic alumina grain self-sharpens during use, reducing glazing and extending wheel life compared to standard aluminum oxide abrasives. It is appropriate for tasks handled by pipefitters, ironworkers, welders, and general fabricators who run 7-inch angle grinders regularly. The threaded hub mount ensures a secure, positive connection to the grinder spindle without additional hardware.

Key Features

• Type 27 depressed center profile provides clearance for flush and surface grinding applications
• Ceramic alumina abrasive delivers high material removal rates and extended wheel life
• Resinoid bond provides durability and consistent performance under load
• 5/8-11 threaded connector fits the standard spindle size on most 7-inch angle grinders
• 1/8-inch thickness optimized for grinding rather than cutting
• 8,600 RPM maximum speed rating for sustained professional use

Compatibility

Designed for use with angle grinders accepting a 7-inch Type 27 wheel with a 5/8-11 threaded spindle mount.

Installation Notes

Installation should be performed by a qualified operator following the grinder manufacturer's wheel mounting instructions and all applicable ANSI B7.1 safety standards for abrasive wheel use. Always inspect the wheel for cracks or chips before mounting and never exceed the rated maximum RPM. Ensure the grinder is fully powered down and unplugged before changing wheels. A proper guard must be in place on the angle grinder before operating.
