Accupro 12184850 Ball End Mill 0.625in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12184850 is a solid carbide ball end mill designed for precision milling operations in metal, composite, and hardened material applications. Built from micrograin solid carbide, it delivers consistent cutting performance and edge retention under demanding conditions. The 4-flute, single-end design with a 40-degree right-hand helix promotes efficient chip evacuation and smooth surface finishes. The mill diameter is 0.625 inches with an uncoated finish, making it suitable for applications where coating selection is handled separately or where bare carbide is preferred for specific material compatibility.

This ball end mill is used in CNC machining centers and manual milling operations for contour milling, profiling, slotting, and finishing passes on ferrous and non-ferrous metals. The stub length configuration and 0.875-inch length of cut make it well suited for shorter-reach applications where rigidity is a priority. Machinists and toolroom operators working in production shops, job shops, and maintenance environments will find this tool appropriate for tight-tolerance work on steel, aluminum, and similar materials.

Key Features

• Micrograin solid carbide construction for improved hardness and wear resistance
• 4-flute geometry with 40-degree right-hand helix for efficient chip flow and surface finish
• 0.625-inch mill diameter with a diameter tolerance of +0.000 to -0.002 inches
• Shank diameter tolerance of -0.0001 to -0.0004 inches for precise tool holder fitment
• Single-end, stub-length design prioritizes rigidity in short-reach setups
• Uncoated finish suitable for dry machining or use with cutting fluids as required

Compatibility

Designed as a standard shank ball end mill compatible with CNC and manual milling machine tool holders accepting a 0.625-inch straight shank, including ER collet chucks, side-lock holders, and hydraulic chucks of the appropriate bore size.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the milling machine spindle is fully powered down and locked out before inserting or removing the end mill from the tool holder. Verify shank seating depth and runout with a dial indicator before beginning a cut. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and cutting conditions.
