Norton 77696097545 Flap Disc 4.5 in Type 27 Aluminum Oxide

Product Description

The NORTON 77696097545 is a Type 27 non-woven flap disc designed for surface blending, light deburring, and finishing work on metal and similar materials. Built around an aluminum oxide abrasive bonded to a fiberglass backing plate, this disc delivers consistent cut and finish performance across its usable life. It measures 4.5 inches in diameter with a 5/8-11 arbor hole, runs at a maximum of 13,300 RPM, and carries a medium grade rating suited to general-purpose surface conditioning. It is installed by metalworkers, fabricators, and maintenance technicians using standard angle grinders.

This flap disc is used in fabrication shops, maintenance facilities, and field metalworking applications where a Type 27 flat-profile disc is required. The non-woven construction provides a softer, more conformable cut compared to coated abrasive flap discs, making it appropriate for light material removal and surface prep on flat and contoured workpieces. The maroon-colored non-woven medium grade is a common choice for blending weld spatter and removing light oxidation without aggressive stock removal.

Compatibility

Designed as an OEM-style replacement flap disc for use with standard angle grinders accepting a 5/8-11 arbor attachment and capable of operating at up to 13,300 RPM.

Installation Notes

Installation and use should be performed by qualified metalworkers or maintenance technicians familiar with angle grinder operation and abrasive safety standards. Verify that the grinder speed rating does not exceed the 13,300 RPM maximum marked on the disc before mounting. Inspect the disc for damage before each use and never operate a damaged or delaminated flap disc. Follow ANSI B7.1 and applicable OSHA standards for abrasive wheel mounting and guarding.
