Accupro 36428415 Ball End Mill 5/64 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 36428415 is a single-end ball end mill designed for precision milling operations in ferrous and non-ferrous metals, hardened steels, and similar demanding materials. It features a 5/64 inch (0.0781 inch decimal) diameter with a 0.0670 inch length of cut and a 2-flute geometry ground from solid carbide for maximum rigidity and edge retention. The AlTiCrN coating provides high-temperature resistance and extended tool life in dry or minimal-lubrication cutting environments. With an overall length of 1-1/2 inches and a 1/8 inch shank diameter, this end mill is sized for small-feature work including contoured profiles, slots, and 3D surface finishing. It is installed and operated by machinists and CNC programmers working on precision components.

This end mill is suited for small-diameter milling applications in machine shops, toolrooms, and production environments. The ball-nose profile makes it appropriate for contouring, radius milling, and finishing passes on curved surfaces. The 0.2500 inch neck length supports reach into shallow cavities without sacrificing rigidity. It is well matched to CNC machining centers and manual knee mills equipped with collet toolholding systems accepting a 1/8 inch shank. Fixed-helix, fixed-index geometry keeps programming and setup straightforward for standard 3-axis work.

Key Features

• Solid carbide construction for superior hardness and wear resistance compared to high-speed steel
• AlTiCrN coating improves heat resistance and extends tool life in high-speed cutting
• 5/64 inch ball-nose diameter enables fine-detail contouring and small-feature machining
• 2-flute design balances chip evacuation and edge strength for small-diameter cutting
• Single-end configuration with 1/8 inch shank for compatibility with standard collet systems
• Fixed helix and fixed index geometry simplify CNC programming and setup

Compatibility

Designed for use in CNC machining centers and manual mills with collet toolholding systems that accept a 1/8 inch shank diameter. No specific compatible machine models were identified in the product data.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Seat the shank fully in the collet or chuck and torque the retention nut to the toolholder manufacturer specification before spindle engagement. Confirm runout with a dial indicator before initiating a cut, as small-diameter carbide tools are sensitive to misalignment. Never exceed the tool manufacturer recommended speeds and feeds for the workpiece material and coating type.
