Accupro 12464114 Ball End Mill 3/64 in 4 Flute Carbide Altin

Product Description

The ACCUPRO 12464114 is a solid carbide ball end mill engineered for miniature milling applications requiring tight tolerances and fine surface finishes. With a 3/64 inch (0.0469 inch) mill diameter and a 0.1410 inch length of cut, this tool is built for small-feature profiling, contouring, and slotting in hard and abrasive materials. The four-flute geometry promotes chip evacuation and rigidity, while the AlTiN coating extends tool life in high-heat cutting conditions. The micrograin carbide substrate adds edge toughness and wear resistance. Machinists and toolmakers working on precision components, molds, and dies will find this tool well-suited to demanding close-tolerance work.

This end mill is designed for use in CNC machining centers and high-speed machining applications where small-diameter, high-precision cutting is required. The 30-degree right-hand spiral helix balances cutting forces and chip flow in both ferrous and non-ferrous materials. With a 1/8 inch shank diameter and 1-1/2 inch overall length, it fits standard collet systems commonly used in vertical machining centers and compact milling machines. It is a single-end tool in the miniature series, appropriate for production and prototype work in tool-and-die, aerospace, and medical manufacturing environments.

Key Features

• Solid carbide micrograin substrate for edge strength and wear resistance in hard materials
• AlTiN coating provides thermal barrier and extended tool life in high-heat cutting conditions
• 4-flute design increases rigidity and improves surface finish in finishing passes
• 30-degree right-hand helix promotes efficient chip evacuation and reduces cutting force
• 0.0469 inch ball diameter with mill diameter tolerance of +0.0000 / -0.0010 inch for tight-tolerance work
• Single-end miniature series construction suited for small-feature profiling and contouring

Compatibility

Designed as an OEM-style replacement or direct-use miniature ball end mill compatible with standard 1/8 inch collet systems on CNC vertical machining centers and high-speed milling machines. No specific model compatibility data was provided by the manufacturer for this SKU.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out state per applicable machine safety procedures. Ensure the collet and collet nut are clean and free of debris before seating the 1/8 inch shank. Verify runout after clamping, as small-diameter carbide tooling is sensitive to collet concentricity. Do not exceed the tool manufacturer's recommended feed and speed parameters for the workpiece material and coating type.
