Accupro 14797439 Ball End Mill 0.0625 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 14797439 is a miniature solid carbide ball end mill designed for high-precision milling operations in ferrous and hardened materials. Built from micrograin carbide stock, it carries an AlTiN coating that improves heat resistance and extends tool life at elevated cutting speeds. At 0.0625 inches in diameter with a 0.094-inch length of cut and a 30-degree helix angle, this tool is engineered for tight-tolerance finish work and fine detail profiling. The two-flute, single-end configuration supports chip evacuation in shallow slots and contoured surfaces. Machinists and CNC operators use this tool where dimensional accuracy and surface finish are the primary requirements.

This end mill is suited for CNC machining centers and manual mills running die and mold work, medical component machining, aerospace detail parts, and precision instrument components. The miniature series designation covers small-diameter tooling where standard end mills are too large for the feature geometry. It is a right-hand cut, right-hand spiral tool with a 1/8-inch shank diameter and 1.5-inch overall length, making it compatible with standard collet chucks and end mill holders in that shank size. No extended reach is incorporated into this design.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention in hardened workpieces
• AlTiN coating provides oxidation resistance and reduced tool wear at high cutting temperatures
• 30-degree helix angle balances cutting forces and chip flow in shallow-depth passes
• Two-flute geometry supports chip clearance in fine-detail and slotting operations
• Single-end design with 0.0625-inch ball diameter for accurate radius profiling and 3D contouring
• Miniature series build with 1/8-inch shank fits standard small-bore collet systems

Compatibility

Designed as a direct-fit miniature ball end mill for CNC machining centers and manual mills using 1/8-inch collet chucks or end mill holders. No specific machine model compatibility was stated in the product data.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the tool changer or collet is de-energized before seating or removing the tool. Verify collet bore size matches the 1/8-inch shank before clamping, and torque the collet nut per the toolholder manufacturer specification. At 0.0625 inches in diameter, this tool is susceptible to breakage from excessive radial engagement or incorrect feed-per-tooth values — confirm toolpath parameters before running.
