Tru-maxx 66254443434 Flap Disc 60 Grit Type 29 7 Inch

Product Description

The TRU-MAXX 66254443434 is a Type 29 zirconia alumina flap disc designed for aggressive material removal on metal surfaces. The 7-inch disc features a 7/8-inch arbor hole and runs at a maximum of 8,600 RPM. It carries a 60-grit coarse rating, making it well-suited for tasks that require fast stock removal alongside a reasonably smooth finish. The poly-cotton backing holds the abrasive flaps securely under load, while the fiberglass backing plate adds rigidity and stability during angled grinding. This disc belongs to the GP-Z series and is built for repeated use in demanding fabrication and maintenance environments.

This flap disc is intended for use on steel and stainless steel. Typical applications include beveling, weld removal, and edge deburring. The Type 29 conical angle allows the disc to make better contact on flat surfaces and in tight contours compared to a flat Type 27 profile. It is commonly used by welders, metal fabricators, pipefitters, and maintenance mechanics who need a fast-cutting abrasive for angle grinder work. The GP-Z series is positioned as a general-purpose zirconia option for both shop and field use.

Key Features

• Type 29 conical profile for improved flat-surface and contour contact
• 60-grit coarse zirconia alumina abrasive for fast stock removal
• Rated to 8,600 RPM maximum for compatibility with standard angle grinders
• Poly-cotton flap backing resists heat buildup and extends disc life
• Fiberglass backing plate provides rigidity and reduces flex under pressure
• Suitable for beveling, weld removal, and edge deburring on steel and stainless steel

Compatibility

Designed for use on steel and stainless steel with standard 7/8-inch arbor angle grinders rated at or below 8,600 RPM. Appropriate for applications including beveling, weld removal, and edge deburring.

Installation Notes

Installation and use should be performed by qualified personnel familiar with angle grinder safety practices. Confirm the grinder's no-load RPM rating does not exceed the 8,600 RPM maximum marked on the disc before mounting. Always inspect the disc for damage before use and ensure the arbor nut is tightened securely per the grinder manufacturer's guidance. Wear appropriate PPE including eye protection and gloves during operation.
