Norton 662530-49104 Type 27 Grinding Wheel 9x1/4 Metal

Product Description

The NORTON 662530-49104 is a Type 27 depressed center grinding wheel built for metal grinding applications. It uses a Gemini aluminum oxide abrasive formulation, which delivers consistent stock removal on steel, iron, and ferrous materials. At 9 inches in diameter with a 1/4-inch thickness and a 5/8-11 threaded arbor hole, this wheel mounts directly to standard large-angle grinders. Rated at a maximum of 6600 RPM, it suits heavy-duty grinding tasks where controlled material removal and wheel durability are required. Fabricators, welders, pipefitters, and ironworkers rely on this type of wheel for weld blending, surface preparation, and edge cleanup on structural and sheet metal.

This grinding wheel is suited for use on steel, stainless steel, and other ferrous metals in fabrication shops, construction sites, and industrial maintenance environments. The Type 27 depressed center profile allows the wheel to lay at a low angle to the workpiece, improving operator control and visibility during surface grinding operations. The 5/8-11 arbor fits the most common spindle thread found on 9-inch angle grinders, making this a direct fit for standard equipment in the field.

Key Features

• Type 27 depressed center profile for low-angle surface grinding and weld blending
• Gemini aluminum oxide abrasive for consistent, controlled stock removal on ferrous metals
• 9-inch diameter and 1/4-inch thickness suited for aggressive material removal
• 5/8-11 threaded arbor compatible with standard large-angle grinder spindles
• 6600 RPM maximum speed rating for use on heavy-duty angle grinders

Compatibility

Designed for use on large-angle grinders with a 5/8-11 spindle thread and a maximum speed rating at or above 6600 RPM. Intended for grinding ferrous metals including structural steel, pipe, and welded assemblies.

Installation Notes

Wheel installation and removal should be performed by a qualified operator following the grinder manufacturer's guard and flange requirements. Always verify the grinder's rated RPM meets or exceeds the wheel's maximum RPM before mounting. Inspect the wheel for cracks or damage before each use and never operate a damaged wheel. Personal protective equipment including a face shield, gloves, and hearing protection is required during operation.
