Accupro 12464148 Ball End Mill 0.059 in 4 Flute Carbide

Product Description

The ACCUPRO 12464148 is a single-end ball end mill designed for precision milling in tight geometries and small-feature work. Built from micrograin solid carbide, it carries an AlTiN coating that extends tool life when cutting hardened steels, stainless, and high-temperature alloys. The cutting diameter is 0.0590 inches with a length of cut of 0.1770 inches, supported by a 1/8-inch shank and an overall length of 1.5 inches. Four spiral flutes with a 30-degree helix angle promote efficient chip evacuation and smooth surface finishes. Licensed machinists and CNC operators in tool-and-die, mold-making, and precision part production are the primary users of this tool.

This end mill is suited for small-feature profiling, contouring, and slotting operations where workspaces are confined and dimensional accuracy is critical. The miniature series designation indicates it is sized for applications requiring fine detail work — common in mold cavities, micro-component machining, and prototype development. Right-hand cut and right-hand flute direction are standard for conventional CNC vertical and horizontal milling setups. No chipbreaker geometry is present, making this tool best suited for finishing and semi-finishing passes rather than heavy roughing.

Key Features

• 0.0590-inch ball nose diameter for precise small-radius contouring
• AlTiN coating for extended wear resistance in ferrous and high-temperature alloy cutting
• Micrograin solid carbide substrate for rigidity and fine edge retention
• 4-flute spiral design with 30-degree helix for balanced chip flow and surface finish
• 1/8-inch shank diameter fits standard miniature collets and tool holders
• Single-end configuration for straightforward tool changes

Compatibility

Designed as an OEM-style replacement or direct-use miniature ball end mill compatible with CNC machining centers and manual mills fitted with collets or tool holders accepting a 1/8-inch shank diameter.

Installation Notes

Installation should be performed by qualified machinists or CNC operators familiar with toolholder torque requirements and runout specifications. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Verify collet bore size matches the 1/8-inch shank before tightening to avoid shank damage or runout. Due to the small diameter, avoid excessive overhang beyond the recommended length of cut to minimize deflection and tool breakage risk.
