Tru-maxx 66254443406 Flap Disc 60 Grit Type 27 7 Inch

Product Description

The TRU-MAXX 66254443406 is a Type 27 zirconia alumina flap disc designed for aggressive material removal and blending on steel and stainless steel surfaces. Rated at 8,600 RPM maximum, this 7-inch disc mounts via a 5/8-11 arbor hole and delivers medium-grade, 60-grit cutting action suitable for weld blending, deburring, and surface prep. The poly-cotton backing provides flexibility while maintaining disc integrity under load. It belongs to the GP-Z series, a coated abrasive line built for general-purpose metalworking applications in fabrication and maintenance environments.

This flap disc is suited for use on angle grinders in metal fabrication shops, structural steel work, pipeline welding prep, and HVAC sheet metal work. The zirconia alumina abrasive self-sharpens during use, extending disc life compared to standard aluminum oxide alternatives. At 60 grit, it balances stock removal speed with surface finish quality, making it practical for both initial grinding passes and intermediate blending stages on ferrous and non-ferrous stainless applications.

Key Features

• Type 27 depressed-center profile for flat surface and edge grinding
• 60 grit zirconia alumina abrasive for self-sharpening, medium-grade material removal
• 8,600 RPM maximum speed rating for use on standard 7-inch angle grinders
• 5/8-11 arbor hole for direct mount compatibility with common grinder spindles
• Poly-cotton backing for controlled flexibility during grinding and blending
• Rated for steel and stainless steel material applications

Compatibility

Designed for use on 7-inch angle grinders with a 5/8-11 spindle thread. Rated for grinding and blending applications on steels and stainless steel.

Installation Notes

Installation and use should be performed by qualified personnel familiar with angle grinder safety practices. Before mounting, verify the grinder's rated no-load RPM does not exceed the disc maximum of 8,600 RPM. Mount the disc securely to the 5/8-11 arbor using the appropriate flange and wrench, ensuring the disc seats flush against the backing flange. Always use the appropriate guard and personal protective equipment including eye protection and gloves during operation.
