Accupro 12465420 Ball End Mill 0.012 in 2 Flute Carbide

Product Description

The ACCUPRO 12465420 is a miniature solid carbide ball end mill designed for precision milling of small-radius features, contoured surfaces, and fine detail work in ferrous and non-ferrous materials. The cutting diameter is 0.0120 inches with a 0.0180-inch length of cut, making it suited for tight-tolerance micro-machining applications. Constructed from micrograin solid carbide, this tool delivers rigidity and edge retention in demanding CNC and manual milling operations. The bright/uncoated finish keeps the tool ready for use without additional prep. A licensed machinist or CNC operator typically selects this tool when fine surface detail or small-cavity geometry is required.

This end mill is intended for light-material removal passes on small components such as mold cavities, medical parts, aerospace features, and precision instrument components. The 0.0120-inch diameter and 0.0180-inch length of cut are best suited for shallow finishing passes rather than heavy roughing. The 1/8-inch shank diameter fits standard collet systems commonly used in CNC machining centers and high-speed spindles. Right-hand cutting and right-hand spiral flute direction are standard for conventional milling setups.

Key Features

• 0.0120-inch ball end cutting diameter for micro-scale milling
• Micrograin solid carbide construction for edge retention and rigidity
• 2-flute spiral design with 30-degree helix angle for efficient chip evacuation
• Bright/uncoated finish suitable for a wide range of work materials
• 1/8-inch shank diameter fits standard collet toolholders
• Single-end configuration with stub-length profile for maximum stiffness

Compatibility

Designed as an OEM-style miniature ball end mill compatible with CNC machining centers and high-speed spindles accepting a 1/8-inch collet or toolholder.

Installation Notes

Installation is performed by a qualified CNC operator or machinist. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the tool from the collet. Use a calibrated torque wrench appropriate to the collet system to secure the shank without over-tightening. Given the 0.0120-inch diameter, verify runout with a dial indicator before beginning any cutting pass, as excessive runout at this scale will cause immediate tool breakage.
