3M 7010363144 Flap Disc 577F 7 Inch 36 Grit

Product Description

The 3M 7010363144 is the 577F flap disc, a coated abrasive tool designed for high-pressure metalworking. Built with alumina zirconia mineral on heavyweight polyester-backed flaps, this 7 inch disc cuts aggressively at 36 grit while leaving a blended finish in a single pass. It is suited for demanding tasks including weld removal, beveling, and sharp-edge work on steel and other metals. The alumina zirconia grain, paired with a grinding aid, delivers more cutting power than standard aluminum oxide and extends disc life under sustained load.

This flap disc is used in industrial and fabrication environments where operators need to grind and blend without switching tools. Typical applications include structural steel fabrication, weld seam cleanup, edge preparation, and surface conditioning on ferrous and non-ferrous metals. The quick-change design reduces changeover time in production settings. It is installed by welders, metal fabricators, and maintenance technicians working with angle grinders in both shop and field conditions.

Key Features

• Alumina zirconia mineral with grinding aid delivers higher cutting power than aluminum oxide on all metal types
• Heavyweight polyester-backed flaps extend disc life on high-pressure applications such as beveling and sharp-edge work
• Combines grinding and blending into a single step, reducing process time
• Quick-change disc design simplifies and speeds disc replacement
• 36 grit provides aggressive stock removal on heavy-duty metalworking tasks

Compatibility

Designed for use on standard angle grinders accepting 7 inch flap discs in metalworking, fabrication, and weld finishing applications.

Installation Notes

Installation and disc changes should be performed by qualified operators following applicable ANSI B7 safety standards for abrasive wheels. Ensure the grinder is unplugged or the power source is isolated before mounting or removing the disc. Verify the grinder RPM rating meets or exceeds the disc maximum RPM before operation. Always use the appropriate guard and personal protective equipment during grinding operations.
