Norton 66252843330 Type 27 Grinding Wheel 5in 24 Grit

Product Description

The NORTON 66252843330 is a Type 27 depressed center grinding wheel designed for aggressive material removal on metal and fabricated steel surfaces. Built with a ceramic alumina abrasive and a coarse 24 grit rating, this wheel cuts fast and holds up under sustained load. The resinoid bond holds the abrasive grains firmly during high-speed grinding passes. It measures 5 inches in diameter with a 1/8 inch thickness and mounts via a standard 5/8-11 threaded hub. At 0.186 pounds, the wheel is lightweight enough for extended overhead or vertical grinding work without adding significant arm fatigue.

This wheel fits standard 5-inch angle grinders and is suited for weld grinding, surface conditioning, and deburring on ferrous metals in fabrication shops, maintenance facilities, and industrial job sites. The Type 27 depressed center profile keeps the grinding face low to the surface, allowing flat grinding passes close to flanges, corners, and weld beads. Licensed trades including ironworkers, pipefitters, welders, and millwrights commonly use this wheel class for prep and cleanup work.

Key Features

• Ceramic alumina abrasive delivers fast, aggressive stock removal on hard metals
• Coarse 24 grit rating suited for rough grinding and weld material removal
• Resinoid bond holds grain firmly through sustained grinding contact
• Type 27 depressed center profile allows flat, low-angle grinding passes
• Standard 5/8-11 threaded mount fits most 5-inch angle grinders
• Lightweight at 0.186 pounds for reduced fatigue during extended use

Compatibility

Designed as a direct-mount replacement for Type 27 depressed center grinding wheels on standard 5-inch angle grinders with a 5/8-11 threaded spindle.

Installation Notes

Installation should be performed by qualified personnel familiar with angle grinder safety and applicable ANSI B7.1 standards for abrasive wheel use. Always power down and disconnect the grinder before mounting or removing any wheel. Inspect the wheel for cracks or chips before mounting and never exceed the maximum RPM rating marked on the wheel. Ensure the threaded flange nut is fully seated before operation and wear appropriate PPE including face shield and gloves.
