Norton 63642502691 Flap Wheel 60 Grit 6x2 in Aluminum Oxide

Product Description

The NORTON 63642502691 is a coated abrasive unmounted flap wheel designed for surface finishing, deburring, and blending on metal and similar industrial materials. Measuring 6 inches in outside diameter by 2 inches wide with a 1-inch center hole, this wheel mounts directly to compatible arbors or spindles without a separate hub. It carries a 60-grit aluminum oxide abrasive on a cloth backing, placing it in the medium grade range — suited for moderate material removal and surface preparation. Rated to a maximum of 6,200 RPM, it is appropriate for use on bench grinders, lathes, and die grinders running within that speed limit. Machinists, fabricators, and metal finishing technicians are the primary installers and operators of this product.

This flap wheel is used in industrial and job-shop environments for blending welds, removing scale, and finishing inside bores or contoured surfaces. The 6 x 2 inch profile makes it well suited for larger-diameter workpieces where a narrower wheel would require multiple passes. The aluminum oxide abrasive performs consistently on ferrous metals, cast iron, and general-purpose steel. It is sold individually and is suitable for production environments requiring reliable, repeatable stock removal at medium grit.

Key Features

• 60-grit aluminum oxide abrasive provides medium-grade cutting action for deburring and surface blending
• Cloth backing adds flexibility and durability through the full service life of the flap segments
• 6-inch outside diameter by 2-inch width suits larger bore and contour finishing applications
• 1-inch center hole fits standard arbor sizes on bench grinders, lathes, and spindle-mounted equipment
• 6,200 RPM maximum rating — compatible with common bench grinder and die grinder speeds
• Non-interleaved construction for direct flap-to-workpiece contact

Compatibility

Designed as an unmounted flap wheel for use on arbors and spindles with a 1-inch bore. Compatible with bench grinders, lathes, and rotary equipment operating at or below 6,200 RPM.

Installation Notes

This flap wheel is installed by trade machinists and metal fabricators on powered rotary equipment. Before mounting, confirm the spindle speed of the host machine does not exceed the 6,200 RPM maximum rating of the wheel. Ensure the arbor diameter matches the 1-inch center hole and that all guards are in place before operation. Do not exceed rated speed, and inspect the wheel for damage before each use in accordance with applicable ANSI abrasive safety standards.
