Accupro 12464076 Ball End Mill 0.033 in 4 Flute Carbide

Product Description

The ACCUPRO 12464076 is a miniature solid carbide ball end mill designed for precision milling of complex contours, radii, and 3D profiles in hardened and difficult-to-machine materials. The 0.0330-inch cutting diameter and 0.0990-inch length of cut make this tool well suited for fine detail work in tight geometries. A four-flute spiral design paired with an AlTiN coating provides thermal stability and extended tool life at elevated cutting temperatures. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces in demanding applications. This tool is installed and operated by machinists and CNC programmers working in tool and die, mold making, aerospace, and medical component manufacturing.

This ball end mill is used in vertical machining centers and CNC milling machines for finish milling, profiling, and contouring passes where small-diameter tooling is required. The 1/8-inch shank diameter allows it to fit standard collets and tool holders sized for miniature end mills. The single-end configuration and 1-1/2-inch overall length make it appropriate for shallow-to-moderate reach applications. AlTiN coating extends usability in dry or semi-dry cutting conditions common in high-speed machining of hardened steels and stainless alloys.

Key Features

• 0.0330-inch ball nose diameter for fine detail and tight-radius milling
• Solid micrograin carbide construction for rigidity and edge retention
• AlTiN coating for heat resistance and extended tool life in ferrous and hardened materials
• Four flutes with right-hand spiral and right-hand cutting direction for efficient chip removal
• 30-degree helix angle reduces cutting forces and promotes smooth surface finish
• Miniature series with 1/8-inch shank for compatibility with standard small-bore collet systems

Compatibility

Designed as an OEM-style miniature ball end mill for use in CNC milling machines and machining centers equipped with collets or tool holders accepting a 1/8-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's tool-change procedures. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the 1/8-inch shank fully into the collet and torque the collet nut to the tool holder manufacturer's specification. Inspect the cutting edges under magnification before use, as miniature carbide end mills are sensitive to chipping from improper handling or excessive runout.
