Value Collection W08B452 Type 27 Grinding Wheel 4.5in

Product Description

The VALUE COLLECTION W08B452 is a Type 27 depressed center grinding wheel designed for aggressive material removal on metal, weld, and fabrication work. Built with aluminum oxide abrasive at 30 grit (Very Coarse grade), it cuts fast and handles heavy stock removal on steel and iron surfaces. The wheel measures 4.5 inches in diameter and 1/8 inches thick, with a 5/8-11 threaded hole for secure mounting on standard angle grinders. A resinoid bond holds the abrasive matrix together under the high heat and shock loads common in grinding applications. Maximum rated speed is 13,300 RPM.

This wheel suits fabrication shops, ironworkers, pipefitters, and welders who need a reliable, coarse-grit grinding wheel for weld blending, surface prep, and edge work. The Type 27 depressed center profile positions the disc below the flange plane, allowing flat or flush grinding against workpiece surfaces. It is compatible with 4.5-inch angle grinders equipped with a 5/8-11 threaded spindle, which is standard on most corded and cordless grinders in this size class.

Installation Notes

Grinding wheels must be installed and operated by personnel familiar with angle grinder safety practices and applicable ANSI B7.1 standards. Before mounting, inspect the wheel for cracks or chips and confirm the grinder spindle speed does not exceed the wheel maximum rating of 13,300 RPM. Always install the proper guard for Type 27 wheels and use appropriate PPE including face shield and gloves. Never exceed the rated RPM or use the wheel on materials outside its rated application.
