Norton 66252843183 Type 27 Grinding Wheel 7 in 30 Grit

Product Description

The NORTON 66252843183 is a Type 27 depressed center grinding wheel designed for aggressive material removal on angle grinders. Built with a zirconia alumina abrasive grain and a resinoid bond, this coarse 30-grit wheel cuts fast and holds up under sustained use. At 7 inches in diameter and 1/8 inch thick, it is rated to 8,600 RPM and features a 5/8-11 threaded arbor for secure mounting. The reinforced construction and T-hardness code make it a reliable choice for grinding welds, deburring metal, and shaping stock in fabrication and maintenance applications.

This wheel is intended for use with angle grinders equipped with a 5/8-11 threaded spindle. The coarse 30-grit zirconia alumina abrasive is well-suited for ferrous and non-ferrous metals where fast stock removal is the priority. Typical applications include weld blending, surface preparation, and edge cleanup in fabrication shops, construction sites, and industrial maintenance settings. The 7-inch diameter suits larger angle grinders commonly used by metalworkers, pipefitters, and ironworkers who need a high-clearance, high-removal wheel.

Key Features

• Type 27 depressed-center profile provides clearance for flat and flush grinding
• Zirconia alumina grain delivers fast cut rates and extended wheel life
• 30 grit coarse grade for aggressive stock removal and weld blending
• 8,600 RPM maximum speed rating for compatibility with angle grinders
• 5/8-11 threaded connector for secure, tool-standard mounting
• Resinoid bond with reinforced construction resists flex and fracture under load

Compatibility

Designed for use with angle grinders equipped with a 5/8-11 threaded spindle and capable of accepting a 7-inch diameter Type 27 grinding wheel.

Installation Notes

Installation and wheel changes must be performed by a qualified operator following the angle grinder manufacturer's guard and flange requirements. Always power down and disconnect the tool before mounting or removing the wheel. Confirm the tool's rated RPM meets or exceeds the wheel's 8,600 RPM maximum before use, and inspect the wheel for cracks or damage before each installation. Grinding wheel safety is governed by ANSI B7.1 standards — follow all applicable guidelines for wheel mounting, guarding, and PPE.
