3M 7010363145 Flap Disc 60 Grit 7 Inch

Product Description

The 3M 7010363145 is a coated abrasive flap disc designed for high-pressure metalworking applications. Built on the 577F platform, it features alumina zirconia mineral bonded to heavyweight polyester-backed flaps that deliver aggressive stock removal and a blended finish in a single pass. At 7 inches in diameter and 60 grit, this disc handles demanding tasks including weld removal, beveling, and sharp-edge deburring. Weighing 0.54 pounds, it is sized for use with standard angle grinders commonly found in fabrication shops, maintenance facilities, and industrial job sites.

This flap disc is suited for ferrous and non-ferrous metal grinding in both shop and field environments. The alumina zirconia mineral, paired with a grinding aid, cuts faster and lasts longer than conventional aluminum oxide discs under sustained load. Typical applications include weld seam blending, surface preparation before coating, edge chamfering, and general stock removal on plate steel, structural members, and pipe. It is used primarily by metal fabricators, welders, pipefitters, and maintenance technicians who require a single disc to grind and blend without switching tools or abrasives.

Key Features

• Alumina zirconia mineral with grinding aid delivers higher cutting power than aluminum oxide across all metal types
• Heavyweight polyester-backed flaps extend disc life on high-pressure applications such as beveling and sharp-edge work
• Flap design combines grinding and blending into one step, reducing tool changes and labor time
• 7 inch diameter and 60 grit configuration suited for aggressive material removal with a controlled finish
• Quick-change disc design simplifies swapping between discs on compatible angle grinders

Compatibility

Designed as an OEM-style replacement flap disc for use on standard 7 inch angle grinders and grinding tools that accept Type 27 or Type 29 coated abrasive flap discs. Confirm arbor size and disc type compatibility with your specific tool before installation.

Installation Notes

Installation should be performed by a qualified operator familiar with angle grinder safety practices. Always power down and disconnect the grinder before mounting or removing the disc. Inspect the disc for damage before each use and do not operate above the rated RPM marked on the disc. Follow applicable ANSI B7.1 and OSHA standards for abrasive wheel mounting and use.
