Accupro 14797509 Ball End Mill 5/64 in 4 Flute Carbide

Product Description

The ACCUPRO 14797509 is a miniature solid carbide ball end mill designed for precision milling in tight geometries and small-feature work. With a 5/64 inch (0.0781 inch) mill diameter and four flutes, it delivers smooth cutting action and improved chip evacuation in hardened and difficult-to-machine materials. The 30-degree right-hand spiral helix reduces cutting forces and vibration, while the AlTiN coating extends tool life in high-heat applications. A micrograin carbide substrate supports edge integrity at the fine tolerances this tool class demands. Licensed machinists and CNC toolroom technicians are the primary users.

This end mill is suited for small-feature profiling, slotting, and contouring operations in ferrous metals, stainless steel, and hardened workpiece materials. The extended reach configuration, with a 0.5900 inch neck length, allows access to recessed features without interference. The 1/8 inch shank diameter fits standard collets on CNC machining centers and manual mills equipped for miniature tooling. It is a single-end tool, making it a direct consumable replacement in high-cycle production environments.

Key Features

• Solid micrograin carbide construction for edge retention in demanding materials
• AlTiN coating provides heat resistance and extended tool life in dry and high-speed cutting
• Four-flute, right-hand spiral configuration with 30-degree helix angle for efficient chip flow
• Extended reach with 0.5900 inch neck length for deep or recessed feature access
• Mill diameter tolerance of +0.0000 / -0.0010 inch for precise dimensional control
• Miniature series design for small-feature CNC milling applications

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 1/8 inch shank collet. Fits standard ER and precision collet systems configured for miniature end mill tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician. Power down and lock out the spindle drive before changing tooling. Seat the shank fully and evenly in the collet to the recommended depth before torquing the collet nut. Inspect the cutting edges and coating for chips or damage before each use, as miniature carbide tools are brittle and sensitive to improper clamping or side loading.
