Norton 66253370849 Type 27 Grinding Wheel 9in Ceramic

Product Description

The NORTON 66253370849 is a Type 27 depressed center grinding wheel designed for aggressive material removal on metal surfaces. Built with a ceramic alumina abrasive grain and a resinoid bond, this wheel delivers a coarse cut suited for weld grinding, surface preparation, and stock removal tasks. The 9-inch diameter and 1/4-inch thickness make it a standard choice for angle grinders used in fabrication, structural steel work, and industrial maintenance. The wheel weighs approximately 1.93 pounds and threads onto a 5/8-11 arbor. Licensed tradespeople and fabricators working on heavy grinding applications rely on this wheel's ceramic alumina construction for consistent cut rate and durability under high-pressure grinding conditions.

This wheel is intended for use on 9-inch angle grinders in both shop and field environments. Its coarse grade and ceramic alumina abrasive make it well suited for carbon steel, stainless steel, and other ferrous metals where fast stock removal is the priority. Typical applications include weld seam grinding, edge cleanup, and surface conditioning on structural components, pipe, and plate. The threaded 5/8-11 hub provides a secure, vibration-resistant connection to compatible grinder spindles.

Key Features

• Ceramic alumina abrasive grain for high cut rate and extended wheel life
• Resinoid bond provides durability and controlled grinding performance
• Coarse grade optimized for rapid stock removal on ferrous metals
• Type 27 depressed center profile reduces interference and improves operator sight lines during grinding
• 5/8-11 threaded hub for secure mounting on standard angle grinders
• Rigid, non-flexible construction maintains consistent contact pressure

Compatibility

Designed for use on 9-inch angle grinders equipped with a 5/8-11 threaded spindle. Verify grinder RPM rating meets or exceeds the maximum RPM marked on the wheel before mounting.

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. Disconnect and lock out power to the grinder before mounting or removing the wheel. Inspect the wheel for cracks or damage before each use and do not use a wheel that shows any signs of damage. Always use the correct flange hardware and ensure the wheel guard is properly in place before grinding.
