Norton 63642502674 Flap Wheel 80 Grit 4x1 in

Product Description

The NORTON 63642502674 is an aluminum oxide unmounted flap wheel designed for surface blending, deburring, and finishing on metal and other hard materials. Running at up to 12,000 RPM, it delivers consistent medium-grade abrasion across contoured and flat surfaces. The wheel measures 4 inches in diameter by 1 inch wide with a 5/8 inch center bore, making it straightforward to mount on standard arbors and die grinders. At 80 grit, it removes material efficiently while leaving a uniform finish suitable for weld cleanup, edge breaking, and general surface prep. Fabricators, machinists, and metal finishing technicians are the primary users of this wheel.

This flap wheel is suited for bench-mounted or handheld rotary tool applications in light industrial, maintenance, and fabrication shop environments. It fits standard arbors with a 5/8 inch shaft. Typical use cases include deburring machined parts, blending weld seams on structural steel, and preparing surfaces prior to coating or inspection. The non-interleaved construction allows the abrasive flaps to contact the workpiece directly, supporting aggressive stock removal at medium grit.

Key Features

• 80 grit aluminum oxide abrasive for medium-grade material removal and surface blending
• 4 inch diameter by 1 inch wide wheel profile for broad surface contact
• 5/8 inch center bore fits standard arbors and die grinder spindles
• 12,000 max RPM rating for use with common rotary power tools
• Non-interleaved flap construction for direct abrasive-to-workpiece contact
• Unmounted design allows use with user-supplied arbor hardware

Compatibility

Designed for use on standard rotary tools, die grinders, and bench arbors accepting a 5/8 inch bore unmounted flap wheel. Verify that the tool spindle speed does not exceed the 12,000 RPM maximum rating before use.

Installation Notes

Installation is performed by machinists or metal fabricators using appropriate arbor hardware matched to the 5/8 inch center bore. Ensure the power tool is disconnected from its power source before mounting or removing the wheel. Never exceed the 12,000 RPM maximum speed marked on the wheel. Wear appropriate PPE including eye protection and gloves when operating abrasive wheels, in accordance with applicable ANSI B11 and OSHA abrasive wheel safety guidelines.
