Accupro 12465772 Ball End Mill 0.018 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12465772 is a solid carbide ball end mill designed for high-precision milling of small features and tight-tolerance workpieces. With a 0.0180-inch cutting diameter and a 0.0270-inch length of cut, this tool is built for miniature machining applications where accuracy and edge integrity are critical. The 4-flute spiral geometry combined with a 30-degree helix angle promotes smooth chip evacuation and stable cutting. An AlTiN coating adds heat resistance and extends tool life in ferrous and hardened materials. Machined from micrograin carbide, this end mill holds a mill diameter tolerance of +0.0000 to -0.0010 inches.

This end mill is well suited for precision milling operations in CNC machining centers handling small mold details, micro-slots, and fine contour work. The 1/8-inch shank diameter fits standard ER collets and miniature tool holders commonly found in high-speed machining setups. Right-hand cut and right-hand flute direction make it compatible with conventional CNC spindle configurations. It is sold as a single-end tool and is intended for use by machinists and tool-and-die professionals working in close-tolerance production or prototype environments.

Key Features

• 0.0180-inch ball cutting diameter with +0.0000 to -0.0010-inch diameter tolerance
• Micrograin solid carbide construction for rigidity and edge sharpness in demanding cuts
• AlTiN coating provides elevated heat resistance for dry or semi-dry machining of hardened steels
• 4-flute spiral design with 30-degree helix angle for efficient chip evacuation and surface finish
• 1/8-inch shank with -0.0001 to -0.0003-inch shank tolerance for secure collet grip
• Miniature series, single-end configuration suited for micro-detail milling work

Compatibility

Designed as an OEM-style miniature ball end mill for use in CNC machining centers and high-speed spindles accepting a 1/8-inch round shank with standard ER or precision collet toolholders.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a safe, locked-out state. Seat the 1/8-inch shank fully and evenly in the collet before tightening to the toolholder manufacturer's specified torque range. Inspect the cutting edges and coating for chips or wear before each setup. Do not exceed the recommended speeds and feeds for the workpiece material and tool diameter to avoid premature breakage at this miniature diameter.
