Norton 63642502675 Flap Wheel 120 Grit 4x1 Inch Aluminum Oxide

Product Description

The NORTON 63642502675 is a coated aluminum oxide unmounted flap wheel designed for surface finishing, blending, and deburring on metal, wood, and composite materials. Measuring 4 inches in outside diameter by 1 inch in width with a 5/8 inch center hole, it mounts on a spindle or mandrel and delivers consistent stock removal and surface conditioning. Rated to a maximum of 12,000 RPM, this fine-grade (120 grit) wheel suits finish-pass work where controlled material removal and smooth surface texture are the goal. The cloth backing provides flexibility and durability across contoured and flat surfaces.

This flap wheel is suited for metalworking, fabrication, and finishing operations in industrial and trade shop environments. It handles weld blending, surface preparation, and edge deburring on steel, aluminum, and similar workpiece materials. The unmounted design requires a compatible arbor or mandrel sized to the 5/8 inch center hole. It is commonly used by machinists, fabricators, and maintenance tradespeople working with bench grinders, drill presses, or rotary tools capable of accepting the appropriate spindle adapter.

Installation Notes

Installation and use of abrasive flap wheels should be performed by qualified tradespeople familiar with abrasive tool safety. Always de-energize and lock out the machine before mounting or removing the wheel. Verify that the spindle speed of the equipment does not exceed the 12,000 RPM maximum rating marked on the wheel before operation. Inspect the wheel for damage before each use and ensure the mandrel or arbor is rated for the wheel diameter and bore size.
