Norton 662528-43234 Blue Fire Type 27 Grinding Wheel 7in

Product Description

The NORTON 662528-43234 is a Blue Fire Type 27 depressed-center grinding wheel sized at 7 x 1/8 x 7/8 inches. Designed for aggressive stock removal on metal, this wheel features Norton's Blue Fire abrasive grain, which self-sharpens during use to maintain a consistent cut rate throughout the wheel's life. The Type 27 profile provides a flat grinding face suited for surface grinding and weld blending at moderate angles. It is installed and used by fabricators, pipefitters, ironworkers, and other trade professionals working with angle grinders.

This wheel is suited for heavy-duty grinding applications on ferrous metals including structural steel, pipe, and weldments. The 7-inch diameter and 1/8-inch thickness make it appropriate for full-size angle grinders in fabrication shops, field construction, and maintenance environments. It is sold in cases of 20 wheels, making it practical for production or crew-level purchasing. Typical applications include weld seam removal, surface prep, and edge cleanup on steel workpieces.

Key Features

• Blue Fire abrasive grain self-sharpens for sustained cut rate and cooler grinding action
• Type 27 depressed-center profile for flat surface and weld blending work
• 7 x 1/8 x 7/8 inch dimensions fit standard 7-inch angle grinders with 7/8-inch arbor
• 1/8-inch thickness optimized for grinding rather than cutting
• Sold in a case of 20 wheels for volume jobsite and shop use

Compatibility

Designed for use on 7-inch angle grinders with a 7/8-inch arbor bore. Verify that the grinder's maximum RPM rating meets or exceeds the wheel's rated speed before installation.

Installation Notes

Installation should be performed by a qualified operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Inspect the wheel for cracks or damage before mounting and never use a damaged wheel. Ensure the grinder is fully powered off and unplugged before changing wheels, and confirm the machine's rated RPM does not exceed the wheel's maximum operating speed. Always use the appropriate guard and personal protective equipment when operating grinding wheels.
