Pferd 61001 Type 27 Depressed Center Wheel 4.5in 24 Grit

Product Description

The PFERD 61001 is a Type 27 depressed center grinding wheel designed for aggressive material removal on steel and stainless steel surfaces. It measures 4.5 inches in diameter and 0.281 inches thick, with a 5/8-11 threaded hub for fast mounting on standard angle grinders. The wheel uses a resinoid bond with aluminum oxide abrasive at 24 grit, placing it firmly in the coarse grade range. Reinforced construction supports a maximum operating speed of 1,300 RPM. This wheel is suited for weld grinding, surface conditioning, and stock removal in fabrication and maintenance applications.

The PFERD 61001 is intended for use on steel and stainless steel workpieces in industrial fabrication, structural steel work, and general metalworking environments. Its Type 27 depressed center profile keeps the grinding face at a consistent angle during flat and beveled surface work. The 4.5-inch diameter fits standard small angle grinders used by welders, pipefitters, and ironworkers in both shop and field conditions. This wheel is sold individually but requires a minimum order of 10 units.

Installation Notes

Installation should be performed by a qualified operator following ANSI B7.1 safety standards for abrasive wheels. Always inspect the wheel for cracks or damage before mounting and never exceed the marked maximum RPM. Power down and disconnect the grinder from its power source before mounting or removing the wheel. Use the correct flange size and ensure the wheel is properly seated and guard is in place before operation.
