3M 7000044994 Type 27 Grinding Wheel 4.5 in Ceramic

Product Description

The 3M 7000044994 is a Type 27 depressed center grinding wheel built for heavy stock removal across a wide range of materials. It uses a ceramic abrasive grain that cuts aggressively and resists breakdown, extending wheel life compared to conventional aluminum oxide options. At 4.5 inches in diameter, this wheel mounts to standard angle grinders and fits applications in fabrication, welding prep, and maintenance where fast, consistent material removal is required. Licensed tradespeople and skilled fabricators working with ferrous metals, stainless steel, alloy steels, and cast iron will find this wheel suited to demanding production and job-site conditions.

This wheel is intended for grinding and stock removal on ferrous metals, stainless steels, alloy steels, and cast iron. It is well suited to fabrication shops, welding operations, and industrial maintenance environments where repeated, heavy-duty grinding is performed. The Type 27 depressed center profile provides clearance for flush and surface grinding tasks. It is sold individually and is compatible with angle grinders and disc grinders that accept Type 27 wheels with the appropriate arbor size and RPM rating.

Compatibility

Designed for use with angle grinders and disc grinders that accept Type 27 depressed center wheels with a matching arbor size and maximum RPM rating equal to or greater than the wheel's rated speed.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety. Confirm that the grinder's rated RPM meets or exceeds the wheel's maximum operating speed before mounting. Always use an approved guard when operating this wheel, and inspect the wheel for cracks or damage before each use. Follow ANSI B7.1 and applicable workplace safety standards when mounting, dressing, or operating grinding wheels.
