3M 7010308897 Flap Disc 4.5 in 36 Grit Quick Change

Product Description

The 3M 7010308897 is a coated abrasive flap disc engineered for high-pressure metalworking applications. It uses alumina zirconia mineral bonded to heavyweight polyester-backed flaps, delivering faster stock removal than standard aluminum oxide discs across steel, stainless, and other metal types. At 4.5 inches in diameter with a 36-grit cut, this disc is built for aggressive material removal. A built-in grinding aid reduces heat and friction during use, extending disc life on demanding tasks like weld removal, sharp-edge work, and beveling. Licensed metalworking technicians and fabricators install and use this disc in production and maintenance environments.

This flap disc is suited for heavy-duty metal fabrication tasks in both shop and field settings. It combines the grinding and blending operations into a single pass, reducing the number of disc changes and tool setups required. The quick-change attachment design speeds up disc swaps, making it practical for high-throughput applications. Typical uses include weld seam removal, edge prep, and surface blending on structural steel, pipe, and plate material.

Key Features

• Alumina zirconia mineral with grinding aid cuts faster than aluminum oxide on all metal types
• Heavyweight polyester-backed flaps extend disc life under high-pressure conditions
• Combines grinding and blending into a single step, reducing process time
• Quick-change disc design simplifies and speeds up disc replacement

Compatibility

Designed as an OEM-style replacement flap disc for standard 4.5-inch quick-change angle grinder systems used in metal fabrication and weld finishing applications.

Installation Notes

Installation and disc changes should be performed by qualified metalworking technicians following the grinder manufacturer's guard and speed rating requirements. Always confirm the disc's maximum RPM rating is compatible with the grinder before mounting. Power down and disconnect the tool from its power source before changing discs. Eye protection, gloves, and appropriate respiratory protection should be worn during grinding operations.
