Pferd 63175 Type 27 Type 42 Grinding Wheel 4.5in 46 Grit

Product Description

The PFERD 63175 is a Type 27 and Type 42 depressed center grinding wheel designed for aggressive material removal on ferrous and stainless steel surfaces. At 4.5 inches in diameter and 0.045 inches thick, this wheel runs on a 7/8 inch arbor and is rated to a maximum of 8,500 RPM. The aluminum oxide abrasive is bonded with a resinoid bond at 46 grit, making it well-suited for cutting and light grinding tasks. It is installed and operated by metalworkers, fabricators, welders, and trade professionals using standard angle grinders.

This wheel is intended for use on steel and stainless steel in metal fabrication, welding prep, and finishing applications. The thin 0.045 inch profile makes it effective for cut-off work and narrow groove cutting in both shop and field environments. Its Type 27 and Type 42 compatibility broadens its use across a range of depressed center angle grinders commonly found in commercial and industrial settings.
