3M 7000119473 Flap Disc 4.5 in 60 Grit Type 29 13300 Rpm

Product Description

The 3M 7000119473 is a Type 29 coated abrasive flap disc engineered for high-pressure metalworking applications. Measuring 4.5 inches in diameter with a 60-grit alumina zirconia abrasive mineral, it grinds and blends in a single pass. A grinding aid is built into the mineral mix to boost cutting power across all metal types. The heavyweight polyester-backed flaps are built for demanding tasks including weld removal, sharp-edge work, and beveling. Rated at 13300 RPM, this disc is sized for standard 4.5-inch angle grinders used daily in fabrication and welding shops.

This flap disc is suited for heavy-duty metalworking in both shop and field environments. Typical applications include weld seam removal, edge chamfering, and surface blending on carbon steel, stainless steel, and other metals. The Type 29 conical geometry places the abrasive at a working angle that increases contact pressure, making it a practical choice for aggressive stock removal where a blended finish is also required in the same operation. Metal fabricators, pipe welders, and ironworkers are the primary installers and users of this product.

Key Features

• Heavyweight polyester-backed flaps extend disc life under high-pressure operating conditions
• Grinds and blends in one step, reducing total time on weld removal and beveling tasks
• Rated at 13300 RPM for compatibility with standard 4.5-inch angle grinders

Compatibility

Designed as a direct-fit replacement flap disc for standard 4.5-inch angle grinders accepting Type 29 coated abrasive discs.

Installation Notes

Mounting and disc changes should be performed with the grinder fully powered off and unplugged or battery removed. Verify the grinder's maximum RPM rating meets or exceeds 13300 RPM before mounting this disc. Follow ANSI B7.1 and applicable OSHA standards for abrasive wheel mounting, guarding, and personal protective equipment. Inspect the disc for damage before each use and do not use a disc that shows signs of cracking, delamination, or excessive wear.
