Pferd 64185115 Type 27 Grinding Wheel 4-1/2 in 46 Grit

Product Description

The PFERD 64185115 is a Type 27 depressed center grinding wheel designed for aggressive material removal on steel surfaces. Built with an aluminum oxide abrasive bond in a resinoid matrix, this wheel delivers consistent cutting action across a range of grinding applications. It measures 4-1/2 inches in diameter with a 7/8-inch arbor hole and is rated to a maximum of 13,300 RPM. The 46-grit designation places it in the coarse range, suited for weld grinding, surface prep, and stock removal. Fabricators, pipefitters, and metalworkers use this wheel with standard 4-1/2-inch angle grinders. At 0.1 pounds, it adds minimal weight to the tool during extended use.

This grinding wheel is intended for use on steel in fabrication shops, field welding operations, and maintenance environments where fast material removal is the priority. The Type 27 depressed center profile allows the wheel to lie nearly flat against the workpiece, making it well suited for surface grinding and weld blending. It mounts via a standard arbor connection compatible with 4-1/2-inch right-angle grinders. The aluminum oxide abrasive and resinoid bond perform reliably on mild and carbon steel in both shop and field conditions.

Installation Notes

Grinding wheel installation and operation should be performed by qualified personnel familiar with ANSI B7.1 safety standards for abrasive wheels. Always power down and unplug or lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before each use and never operate above the rated maximum RPM. A proper flange and locking nut appropriate for the arbor size must be used to secure the wheel correctly.
