Product Description
The MERIT ABRASIVES 66254420269 is a unitized aluminum oxide deburring wheel designed for edge finishing, light deburring, and surface blending on metal workpieces. Built to a Density 6 construction, this wheel balances conformability with cutting action, making it well-suited for work on contoured and flat surfaces alike. It is rated to 22,000 RPM, allowing it to run safely on high-speed rotary tools. The 2-inch diameter and 1/2-inch face width keep the wheel compact for precise control in tight areas. Machinists, fabricators, and metalworking tradespeople are the primary users of this type of wheel.
This deburring wheel is sized for use with die grinders, which are standard handheld tools in metal fabrication shops, welding operations, and maintenance environments. The 1/4-inch center hole mounts directly to standard die grinder mandrels without adapters. It is appropriate for deburring drilled holes, cleaning weld seams, blending edges on mild steel, stainless steel, and similar metals. The fine-grade aluminum oxide abrasive removes burrs and light surface irregularities while leaving a consistent finish. This wheel suits both shop and field work where a small, controllable abrasive tool is needed.
Key Features
- Unitized wheel construction abrasive fibers bonded throughout for consistent performance as the wheel wears
- Aluminum oxide abrasive effective on ferrous metals and general-purpose metalworking applications
- Density 6 with fine grade controlled cut rate suited for light deburring and surface blending
- 22,000 RPM maximum speed compatible with standard die grinder operating speeds
- 1/4-inch center hole direct mount to common die grinder mandrels
- Compact 2-inch x 1/2-inch profile provides access to tight spots and contoured workpiece geometry
Compatibility
Designed for use with die grinders accepting a 1/4-inch arbor. Verify that the tool’s rated no-load RPM does not exceed 22,000 RPM before mounting this wheel.
Installation Notes
Mounting and use of abrasive wheels should follow ANSI B7.1 safety standards and applicable shop safety protocols. Power down and disconnect the die grinder from its air supply or electrical source before mounting or removing the wheel. Inspect the wheel for cracks or damage before each use do not use a damaged wheel. Always run the wheel at or below its 22,000 RPM maximum speed rating.
