Norton 63642502633 Mounted Flap Wheel 80 Grit 1-3/8 in

Product Description

The NORTON 63642502633 is a threaded-mount flap wheel designed for precision grinding, blending, and finishing on metal and other hard surfaces. Built with aluminum oxide abrasive on a cloth backing, this wheel delivers consistent cutting action at a medium 80 grit rating. The 1-3/8 inch diameter and 5/8 inch face width make it well suited for working in confined areas and on contoured surfaces where flat abrasive wheels cannot reach. Rated to 30,000 RPM maximum, it is compatible with die grinders and other high-speed rotary tools commonly used in fabrication and finishing applications. Installation requires a threaded mandrel. Weight is 0.05 pounds.

This mounted flap wheel is used in metal fabrication shops, welding operations, tool and die work, and general surface conditioning tasks. The aluminum oxide grain is effective on carbon steel, alloy steel, and cast iron. Its compact diameter and threaded mount make it a practical choice for blending weld seams, deburring edges, and smoothing internal bores or contoured profiles where larger abrasives would not fit. Licensed tradespeople and skilled fabricators in production and maintenance settings typically use this wheel with pneumatic or electric die grinders.

Key Features

• Aluminum oxide coated abrasive on a cloth backing for durable, consistent stock removal
• 80 grit medium grade suitable for blending, deburring, and light surface conditioning
• 1-3/8 inch outside diameter and 5/8 inch face width for access in tight and contoured areas
• Threaded mount for secure attachment to standard mandrels on die grinders
• 30,000 RPM maximum speed rating for use with high-speed rotary tools
• No interleaf construction for direct abrasive contact and aggressive flap action

Compatibility

Designed as an OEM-style mounted flap wheel for use with threaded mandrels on pneumatic and electric die grinders rated for the stated maximum RPM.

Installation Notes

A licensed machinist, fabricator, or trained technician should install this wheel on a compatible threaded mandrel before mounting to the die grinder. Always verify the tool spindle speed does not exceed 30,000 RPM before operation. Power down and disconnect the grinder from its air supply or electrical source before changing abrasive accessories. Wear appropriate personal protective equipment including eye and face protection during use.
