Norton 63642502677 Flap Wheel 4x2 in 60 Grit Aluminum Oxide

Product Description

The NORTON 63642502677 is a coated abrasive unmounted flap wheel designed for grinding, blending, and finishing on metal and other hard surfaces. Built with aluminum oxide abrasive bonded to a cloth backing, this flap wheel delivers consistent stock removal at medium grade. The 4-inch outside diameter and 2-inch face width provide a broad contact surface, while the 5/8-inch center hole accepts standard arbor mountings. Rated to a maximum of 12,000 RPM, it suits bench-mounted or handheld spindle applications in fabrication, welding, and surface prep work. Metalworkers, pipefitters, and general fabrication shops are the typical end users.

This flap wheel is used in industrial and trade settings where controlled surface finishing is required on metal workpieces. Common applications include weld seam blending, edge deburring, and surface conditioning prior to coating or inspection. The medium-grade, 60-grit configuration makes it well suited for moderate stock removal where a finer finish than a grinding wheel is needed but aggressive cutting is still required. It is sold individually and fits standard spindle arbor setups.

Key Features

• Aluminum oxide abrasive for durable, consistent cut on metal surfaces
• Cloth backing provides flexibility and resistance during flap contact
• Medium grade, 60 grit — effective for weld blending and surface conditioning
• 12,000 RPM maximum rating suits bench and handheld spindle use
• 5/8-inch center hole fits common arbor mount configurations

Compatibility

Designed for use on standard spindle arbors accepting a 5/8-inch center hole unmounted flap wheel in fabrication and metalworking applications.

Installation Notes

Mounting should be performed by a qualified operator familiar with abrasive wheel safety. Before mounting, verify the spindle speed does not exceed the 12,000 RPM maximum rating marked on the wheel. Ensure the arbor and flanges are clean and properly sized for the 5/8-inch center hole before securing. Always install and operate abrasive wheels in accordance with ANSI B7.1 safety standards and the tool manufacturer guidelines.
