Accupro 14797421 Ball End Mill 1/16 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 14797421 is a miniature solid carbide ball end mill designed for precision milling of small features, contours, and curved surfaces. With a 1/16 inch (0.0625 inch) mill diameter and a 0.1860 inch length of cut, this tool is built for tight-tolerance work in confined areas. The two-flute geometry with a 30-degree helix angle promotes efficient chip evacuation during high-speed passes. An AlTiN coating provides thermal resistance and extended tool life in ferrous and hardened materials. Machining professionals and tool-and-die shops use this end mill for finish profiling, 3D contouring, and slotting operations where a small-radius ball nose is required.

This miniature end mill is suited for CNC milling applications in precision machining environments, including mold making, die work, aerospace component finishing, and medical device machining. The single-end configuration and 1/8 inch shank diameter make it compatible with standard collet systems used on vertical machining centers and high-speed spindles. Its micrograin carbide substrate supports rigidity and edge retention in both dry and mist-cooled cutting conditions.

Key Features

• 1/16 inch (0.0625 inch) ball nose diameter for fine-detail milling
• 0.1860 inch length of cut for precise depth engagement
• 2-flute, right-hand spiral configuration promotes chip flow
• 30-degree helix angle balances cutting forces and surface finish
• AlTiN coating extends tool life in ferrous and hardened workpieces
• Micrograin solid carbide substrate for rigidity and edge retention

Compatibility

Designed as a miniature single-end ball end mill for use in CNC machining centers and high-speed milling spindles equipped with standard collet systems accepting a 1/8 inch shank diameter.

Installation Notes

Installation and tool changes must be performed by qualified machinists with the spindle fully stopped and machine controls locked out. Ensure the collet and toolholder are clean and free of debris before seating the 1/8 inch shank. Confirm runout with a dial indicator after clamping, as miniature diameter end mills are sensitive to even minor runout. Consult the machine manufacturer and applicable shop safety standards for proper speeds and feeds before cutting.
