Value Collection W08B450 Type 27 Grinding Wheel 4.5in

Product Description

The VALUE COLLECTION W08B450 is a Type 27 depressed center grinding wheel built for aggressive material removal on angle grinders and right-angle grinding tools. Measuring 4.5 inches in diameter and 0.25 inches thick, it uses a 24-grit aluminum oxide abrasive bonded with a resinoid bond for durability under sustained grinding loads. The 5/8-11 threaded arbor hole provides a secure, direct mount to standard angle grinder spindles. Rated to 13,300 RPM, this wheel is suited for stock removal, weld blending, and surface prep on ferrous metals. Metalworkers, fabricators, pipefitters, and maintenance techs are the typical users.

This grinding wheel is designed for use on angle grinders in fabrication shops, construction sites, and industrial maintenance environments. The Type 27 depressed center profile keeps the grinding face flush to the workpiece, making it effective for flat surface grinding and weld seam removal. The very coarse 24-grit rating prioritizes fast metal removal over surface finish, making it appropriate for roughing passes on structural steel, pipe, and plate rather than finishing work.

Key Features

• Type 27 depressed center profile for flat surface and weld grinding
• 24-grit aluminum oxide abrasive rated Very Coarse for high-speed stock removal
• Resinoid bond provides impact resistance during heavy grinding passes
• 13,300 RPM maximum speed rating for use with standard 4.5-inch angle grinders
• 5/8-11 threaded connector mounts directly to common angle grinder spindles
• Sold in a package quantity of 20 wheels per order

Compatibility

Designed for use with angle grinders accepting a 4.5-inch diameter Type 27 wheel with a 5/8-11 threaded arbor connection. Verify that the grinder spindle speed does not exceed the 13,300 RPM wheel rating before use.

Installation Notes

Installation should be performed by a qualified operator following the grinder manufacturer guidelines and applicable ANSI B7.1 safety standards for abrasive wheel use. Always power down and unplug or lockout the grinder before mounting or removing a wheel. Inspect the wheel for cracks or damage before each use and never exceed the marked maximum RPM. Use the correct guard for Type 27 wheels and ensure the 5/8-11 arbor nut is fully tightened with the appropriate wrench before operation.
