Merit Abrasives 63642593980 Deburring Wheel 3 in Aluminum Oxide

Product Description

The MERIT ABRASIVES 63642593980 is a unitized aluminum oxide deburring wheel designed for edge finishing, light deburring, and surface blending on metal workpieces. It measures 3 inches in diameter with a 3/4-inch face width and mounts via a 1/4-inch center hole, making it a direct fit for die grinders commonly used in fabrication, welding, and machining shops. The wheel is rated at a maximum of 18,000 RPM and carries a Density 6, medium-grade abrasive construction that balances cut rate with surface finish quality. Licensed tradespeople and skilled fabricators use this wheel for finishing weld seams, deburring drilled holes, and cleaning up cut edges on ferrous and non-ferrous metals.

This deburring wheel suits light to medium deburring and blending tasks in both production and maintenance environments. Its unitized construction means the abrasive grains are distributed throughout the wheel matrix, allowing the wheel to wear evenly and continuously expose fresh cutting material during use. Typical applications include weld cleanup, burr removal on machined components, and surface conditioning in metal fabrication settings. The 1/4-inch arbor and compact 3-inch diameter make it well suited to handheld die grinder use in tight clearances and confined work areas.

Key Features

• Unitized wheel construction provides consistent cut throughout the life of the wheel
• Aluminum oxide abrasive material suitable for ferrous and non-ferrous metal applications
• Medium grade, Density 6 rating balances material removal with surface finish
• 3-inch diameter and 3/4-inch face width in a compact, die grinder-ready form factor
• 1/4-inch center hole mounts directly to standard die grinder mandrels
• 18,000 RPM maximum speed rating for use with high-speed die grinders

Compatibility

Designed for use with die grinders accepting a 1/4-inch arbor. Confirm the spindle speed of the host tool does not exceed the 18,000 RPM maximum rating of this wheel before mounting.

Installation Notes

Installation should be performed by a qualified technician familiar with abrasive wheel safety. Always power down and disconnect the die grinder from its air or electrical supply before mounting or removing the wheel. Verify that the tool's rated RPM does not exceed the 18,000 RPM maximum speed of this wheel. Inspect the wheel for damage before each use and follow ANSI B7.1 safe practice guidelines for the use, care, and protection of abrasive wheels.
