Pferd 62176 Flap Disc 40 Grit Type 27 4.5 X 0.875 Inches

Product Description

The PFERD 62176 is a Type 27 zirconia alumina flap disc engineered for aggressive stock removal on carbon steel and stainless steel. The disc measures 4.5 inches in diameter with a 0.875-inch arbor hole and carries a 40-grit abrasive rating for coarse cutting and blending work. Zirconia alumina grains self-sharpen as they wear, continuously exposing fresh cutting edges. This grain breakdown cycle sustains cut rates and reduces heat buildup compared to standard aluminum oxide discs. Licensed fabricators, welders, and metalworkers reach for this disc when they need fast material removal without excessive workpiece discoloration.

The PFERD 62176 suits angle grinder applications in metal fabrication shops, structural steel work, pipeline maintenance, and weld prep or weld cleanup tasks. Its Type 27 flat-profile geometry positions the abrasive surface nearly parallel to the workpiece, making it well-suited for surface grinding and blending passes rather than edge work. It performs on both ferrous and non-ferrous stainless applications where cool cutting is a priority, particularly on heat-sensitive stainless steel where discoloration and metallurgical change must be minimized.

Key Features

• Zirconia alumina abrasive grains self-sharpen under load for sustained cut rate
• Cuts cooler than aluminum oxide, reducing heat-related discoloration on stainless steel
• 40-grit rating delivers aggressive stock removal with moderate surface finish
• Type 27 flat profile optimized for surface grinding and blending
• 4.5-inch diameter with 0.875-inch arbor fits standard angle grinders

Compatibility

Designed as a direct-fit replacement flap disc for standard 4.5-inch angle grinders accepting a 0.875-inch arbor, compatible with tools used for carbon steel and stainless steel surface grinding and blending applications.

Installation Notes

Installation is performed by metalworkers and fabricators using a standard 4.5-inch angle grinder. Always power down and disconnect the grinder from its power source before mounting or removing the disc. Verify the grinder's maximum RPM rating meets or exceeds the disc's rated RPM before use, and inspect the disc for cracks or damage prior to each installation. Follow ANSI B7.1 and tool manufacturer guidelines for abrasive wheel mounting and guarding.
