Accupro 14797395 Ball End Mill 0.012 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 14797395 is a miniature solid carbide ball end mill designed for high-precision milling in tight geometries and fine-detail work. With a 0.012 inch cutting diameter and a 0.018 inch length of cut, this tool is built for micro-scale profiling, slotting, and contouring in hardened metals, tool steels, and aerospace alloys. The AlTiN coating provides thermal resistance and extends tool life in high-heat cutting environments. The 30-degree helix angle promotes efficient chip evacuation in small-diameter applications. This end mill is typically installed and used by machinists, tool and die makers, and precision CNC programmers working in high-accuracy environments.

This ball end mill is suited for miniature milling operations in CNC machining centers handling complex 3D contours, mold cavities, and fine surface finishing passes. The single-end, two-flute configuration is well-matched to applications requiring maximum chip clearance in small-diameter cuts. The 1/8 inch shank fits standard collets and tool holders commonly found in vertical machining centers and high-speed spindle setups. Its micrograin carbide substrate supports rigidity and edge retention at this scale, making it appropriate for ferrous and non-ferrous materials in precision production and prototype work.

Key Features

• 0.012 inch ball diameter with 0.018 inch length of cut for micro-scale milling
• AlTiN coating for heat resistance and extended tool life in hardened and alloy materials
• Micrograin solid carbide substrate for rigidity and sharp edge retention at miniature scale
• 30-degree right-hand helix with right-hand cutting direction for efficient chip flow
• 1/8 inch shank diameter compatible with standard collet-style tool holders
• Single-end, two-flute spiral configuration optimized for fine contouring and profiling passes

Compatibility

Designed as a miniature series replacement-style ball end mill compatible with CNC machining centers using standard 1/8 inch collet or tool holder systems.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. At this diameter, runout control is critical - use a precision collet or shrink-fit holder and verify runout with a dial indicator before cutting. Do not exceed the recommended depth of cut for the stated length of cut, as tool deflection and breakage risk increase significantly at sub-0.015 inch diameters.
