Merit Abrasives 66254420270 Deburring Wheel 1 Inch

Product Description

The MERIT ABRASIVES 66254420270 is a unitized deburring wheel designed for light material removal, edge blending, and surface finishing on metal workpieces. Constructed with aluminum oxide abrasive at a density of 6, this wheel delivers consistent cutting action suited for fine finishing work. The 1-inch diameter and 1-inch face width make it a compact solution for detailed deburring operations, and the 3/16-inch center hole mounts directly to die grinder mandrels. Rated to 30,000 RPM, it handles the high-speed output typical of pneumatic and electric die grinders used in fabrication and maintenance shops.

This wheel is used in metalworking applications where controlled deburring, light stock removal, or edge preparation is required. Its unitized construction — in which abrasive grains are distributed throughout a non-woven fiber matrix — allows the wheel to wear evenly and maintain consistent performance throughout its life. Typical applications include deburring drilled holes, cleaning up machined edges, and blending weld areas on ferrous and non-ferrous metals. The compact 1-inch form factor suits confined areas and intricate part geometries where larger wheels cannot reach.

Key Features

• Aluminum oxide abrasive for reliable cutting action on metal substrates
• Density 6 unitized construction for even wear and consistent finish throughout wheel life
• 1-inch diameter by 1-inch face width suits detail work and confined spaces
• 3/16-inch center hole mounts to standard die grinder mandrels
• 30,000 RPM maximum speed rating compatible with high-speed pneumatic and electric die grinders
• Fine grade abrasive for smooth surface finish on finished or near-finished parts

Compatibility

Designed for use with die grinders. Mounts via a 3/16-inch center hole to standard mandrel accessories compatible with that bore size.

Installation Notes

Installation and use of abrasive wheels should be performed by qualified personnel familiar with abrasive safety standards, including ANSI B7.1 guidelines for the use, care, and protection of abrasive wheels. Always confirm the spindle speed of the die grinder does not exceed the 30,000 RPM maximum rated speed of the wheel before mounting. Ensure the mandrel and center hole are clean and free of damage before seating the wheel. Wear appropriate PPE including eye protection and gloves during wheel mounting and operation.
