Pferd 47801427 Mounted Flap Wheel 80 Grit 3 in Zirconia Alumina

Product Description

The PFERD 47801427 is a mounted flap wheel designed for use with straight grinders in metal fabrication, maintenance, and finishing applications. It measures 3 inches in outside diameter with a 1-inch face width and features zirconia alumina abrasive on a cloth backing. The 1/4-inch shank diameter and 1-1/2-inch shank length allow secure mounting in standard straight grinder collets. Rated for a maximum of 20,000 RPM, this wheel delivers consistent stock removal and blending at medium grit (80). Zirconia alumina is a self-sharpening abrasive that performs well on tough alloys and hard metals, making it a durable choice for production grinding tasks.

This mounted flap wheel suits metalworking professionals who need to grind, blend, or deburr in tight or contoured areas where larger wheels cannot reach. It is rated for use on a broad range of materials including stainless steel, carbon steel, cast steel, heat-treatable steel, aluminum, brass, bronze, copper, titanium, cobalt-based alloys, nickel-base alloys, nodular cast iron, annealed cast iron, and other non-ferrous metals. It is installed and operated by machinists, fabricators, tool and die technicians, and maintenance mechanics working in shop or field environments.

Key Features

• Zirconia alumina abrasive on cloth backing — self-sharpening for extended wheel life on hard metals
• 80 grit (medium) for aggressive stock removal and surface blending
• 3-inch outside diameter and 1-inch face width for broad contact on flat and contoured surfaces
• 1/4-inch shank diameter fits standard straight grinder collets
• 20,000 RPM maximum rated speed for compatibility with high-speed die and straight grinders
• Rated for use on a wide range of ferrous and non-ferrous metals including titanium and nickel-base alloys

Compatibility

Designed for use with straight grinders equipped with a 1/4-inch collet. Suitable for grinding, blending, and deburring on aluminum, stainless steel, steel, cast iron, brass, bronze, copper, titanium, cobalt-based alloys, nickel-base alloys, and other non-ferrous metals as specified by the manufacturer.

Installation Notes

Installation is performed by machinists or fabricators following standard grinder safety procedures. Always verify the grinder spindle speed does not exceed the 20,000 RPM maximum rating of this wheel before mounting. Power down and disconnect the grinder from its power source before installing or removing the shank. Wear appropriate PPE including eye protection and gloves, and confirm the shank is fully seated and the collet nut is properly tightened before operation.
