Accupro 12183951 Ball End Mill 0.1969 in 2 Flute Carbide Ticn

Product Description

The ACCUPRO 12183951 is a solid carbide ball end mill designed for precision milling operations across a wide range of materials. It features a 0.1969-inch (5 mm) mill diameter and a 0.6299-inch (16 mm) length of cut, with a 2-flute, single-end configuration optimized for both slotting and profiling in tight geometries. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. A TiCN coating adds surface hardness and wear resistance, extending tool life in abrasive or high-temperature cutting environments. Machinists and CNC operators working in job shops, tool rooms, or production facilities are the primary users of this tool.

This ball end mill is suited for finish and semi-finish milling of contoured surfaces, pockets, and 3D profiles in materials including steel, stainless steel, cast iron, and non-ferrous alloys. The micrograin carbide substrate supports rigidity and edge retention at small diameters. With a 6 mm (0.2362-inch) shank diameter and a 63 mm (2.48-inch) overall length, it is compatible with standard collet chucks and end mill holders commonly found on vertical machining centers and CNC mills.

Key Features

• 0.1969-inch (5 mm) ball nose diameter for contour and profile milling
• TiCN coating for improved wear resistance and surface hardness
• 40-degree helix angle for efficient chip evacuation and reduced cutting forces
• Micrograin solid carbide substrate for edge retention at small diameters
• 2-flute, right-hand cut and right-hand spiral configuration
• Single-end design with 6 mm shank for standard collet and end mill holder compatibility

Compatibility

Designed for use in standard collet chucks and end mill holders accepting a 6 mm shank diameter, as found on vertical machining centers and CNC milling machines.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle powered down and the machine in a safe, locked-out state. Ensure the collet or tool holder is clean and free of debris before seating the shank. Verify runout with a dial indicator after clamping, as excessive runout will reduce tool life and surface finish quality at this diameter. Follow the machine and tooling manufacturer guidelines for speeds and feeds appropriate to the workpiece material.
