Widia 2864573 Ball End Mill 0.25in 2-flute Solid Carbide

Product Description

The WIDIA 2864573 is a solid carbide ball end mill designed for precision milling of non-ferrous metals. It features a 0.25-inch diameter with a matching 0.25-inch straight cylindrical shank, a 0.75-inch length of cut, and a 2.5-inch overall length. The 37-degree medium helix angle promotes efficient chip evacuation during both roughing and finishing operations. With two right-hand spiral flutes and a bright uncoated finish, this single-end mill is suited for applications where coating is not required. Machinists and CNC operators typically install this tool in end mill holders or collet chucks on vertical or horizontal machining centers.

This end mill is intended for use with non-ferrous metal workpiece materials, including aluminum, copper, and similar alloys. Its standard-length geometry and 0.75-inch reach make it a practical choice for general-purpose profiling, contouring, and finishing cuts where a ball nose profile is required. It belongs to WIDIA Series 4A01 and carries catalog number 4A0107002. The uncoated carbide substrate performs well in non-ferrous applications where heat generation is typically lower and coating adhesion is less critical.

Key Features

• 0.25-inch ball end diameter with 0.125-inch nose radius for accurate contour and profile work
• Solid carbide construction for rigidity and wear resistance in non-ferrous milling
• 37-degree medium helix angle for efficient chip flow during roughing and finishing
• Two right-hand spiral flutes with bright uncoated finish
• Single-end design with straight cylindrical shank for standard toolholding compatibility
• Rated for both roughing and finishing material removal operations

Compatibility

Designed as an OEM-style replacement in the WIDIA Series 4A01 line, catalog number 4A0107002, intended for use in standard 0.25-inch end mill holders or collet chucks on CNC or manual machining centers processing non-ferrous metal workpieces.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. The machine spindle must be fully powered down and stopped before changing tooling. Verify that the collet or end mill holder bore matches the 0.25-inch shank diameter before securing the tool. Follow the machine tool manufacturer torque specifications for the toolholder being used, and confirm runout with a dial indicator before beginning the cut.
