Norton 66252839426 Type 27 Grinding Wheel 5in 24 Grit

Product Description

The NORTON 66252839426 is a Type 27 depressed center grinding wheel designed for aggressive material removal on metal surfaces. Built with ceramic alumina abrasive and a coarse 24 grit rating, this wheel cuts fast and holds up under sustained load. The resinoid bond holds abrasive grains firmly during high-stress grinding passes. Rated to a maximum of 12,225 RPM, it is sized at 5 inches in diameter with a 1/8-inch thickness and a 7/8-inch arbor hole. This wheel suits fabricators, ironworkers, pipefitters, and welders who need consistent stock removal on ferrous and other hard materials.

This wheel fits standard 5-inch right-angle grinders commonly used in structural steel fabrication, weld prep, weld cleanup, and pipe fitting applications. The Type 27 depressed center profile keeps the mounting hardware below the grinding face, allowing a low grinding angle and good clearance in tight areas. It is well-suited for heavy-duty grinding on mild steel, stainless steel, and similar hard metals in both shop and field environments.

Key Features

• Ceramic alumina abrasive for aggressive, fast cutting action on hard metals
• Coarse 24 grit rating delivers rapid stock removal
• Resinoid bond provides durability and grain retention under load
• Type 27 depressed center profile allows low-angle grinding with arbor clearance
• 12,225 RPM maximum speed rating for use with standard 5-inch angle grinders
• Rigid, non-flexible construction for controlled surface grinding

Compatibility

Designed for use with 5-inch right-angle grinders fitted with a 7/8-inch arbor. Confirm grinder RPM rating meets or exceeds the 12,225 RPM maximum before mounting.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety. Always power down and unplug or lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before each use and never operate above the marked maximum RPM. Eye protection, gloves, and appropriate PPE are required during grinding operations per ANSI B11 and OSHA abrasive wheel standards.
