Norton 63642502673 Flap Wheel 60 Grit 4x1 in

Product Description

The NORTON 63642502673 is an aluminum oxide unmounted flap wheel designed for surface blending, deburring, and finishing on metal and other hard materials. At 4 inches in diameter and 1 inch wide, with a 5/8 inch center hole, it mounts to compatible arbors on bench grinders, drill presses, or portable power tools. The 60 grit rating places it in the medium grade range, making it effective for moderate stock removal while leaving a consistent finish. Maximum operating speed is 12,000 RPM. This type of abrasive is a standard choice for fabricators, machinists, and metalworkers handling edge work and surface preparation tasks.

This flap wheel is suited for use in metal fabrication shops, maintenance and repair environments, and light manufacturing settings. It handles deburring of cut edges, blending weld seams, and general surface conditioning on ferrous and non-ferrous metals. The unmounted design requires a separate arbor or mandrel sized to the 5/8 inch center hole. It is typically used with stationary grinding equipment or handheld power tools capable of reaching the rated RPM range.

Key Features

• Aluminum oxide abrasive construction for consistent cut on metal surfaces
• 60 grit medium grade for moderate stock removal and surface blending
• 4 inches diameter x 1 inch wide — compact size for detail and edge work
• 5/8 inch center hole for compatibility with standard arbors and mandrels
• 12,000 max RPM rating for use with common bench and portable power equipment
• No interleaf construction for direct abrasive contact

Compatibility

Designed for use with arbors or mandrels fitted to the 5/8 inch center hole specification. Suitable for bench grinders, drill presses, and rotary power tools capable of accommodating the 4 x 1 inch wheel size and operating at or below 12,000 RPM.

Installation Notes

Mounting and removal should be performed with the power source fully de-energized and locked out before handling the wheel. Verify that the arbor or mandrel matches the 5/8 inch center hole and that the tool's maximum RPM does not exceed the wheel's 12,000 RPM rating. Always inspect the flap wheel for damage before mounting. Follow applicable ANSI B7.1 safety requirements for the use of abrasive wheels.
