Norton 77696090148 Flap Disc 80 Grit Type 27 2 Inch

Product Description

The NORTON 77696090148 is a Type 27 ceramic alumina flap disc designed for aggressive material removal on angle grinders and die grinders fitted with a Quick-Change Type R attachment system. Rated at 80 grit medium grade, this coated abrasive disc delivers consistent cut rate and surface finish on steel, stainless steel, and other ferrous metals. The fiberglass backing provides rigidity and support across the 2-inch disc face, and the disc is rated to a maximum of 30,000 RPM for use at high spindle speeds common to right-angle and straight die grinders.

This flap disc is suited for light fabrication, weld blending, and surface conditioning work in industrial, maintenance, and repair settings. The 2-inch diameter and Quick-Change Type R mount make it a practical choice for technicians and tradespeople working in tight spaces or on smaller workpieces where a standard large-diameter disc would be unwieldy. Sold individually, it is available in minimum order multiples of 10.

Installation Notes

Installation and disc changes should be performed with the grinder unplugged or the power source isolated. Verify the grinder spindle speed does not exceed the 30,000 RPM maximum rating marked on the disc before operation. Always inspect the disc for damage before mounting, and ensure the Quick-Change Type R arbor is clean and fully engaged before starting the tool. Personal protective equipment including eye protection and gloves is required during disc changes and grinding operations per ANSI and OSHA standards.
