Accupro 14797470 Ball End Mill 0.0469 in 3 Flute Carbide

Product Description

The ACCUPRO 14797470 is a miniature series ball end mill designed for precision milling of small-diameter features in hardened and difficult-to-machine materials. Built from micrograin solid carbide, this single-end tool carries a 0.0469 inch (3/64 inch) ball diameter and a 0.375 inch length of cut, making it well-suited for profiling, contouring, and slotting tight geometries. The AlTiN coating extends tool life at elevated cutting temperatures, a key advantage when running higher surface speeds in ferrous alloys, stainless, and hardened steels. Machinists and tooling specialists in production and job-shop environments select this cutter for applications where small-scale precision is non-negotiable.

This end mill fits into CNC machining centers, high-speed spindles, and manual mills equipped with a 1/8 inch shank collet or chuck. Its miniature series classification makes it a natural choice for die and mold work, medical component machining, aerospace detail parts, and any operation requiring a long-reach, small-diameter ball profile. The 2.5 inch overall length provides additional reach into deep cavities without sacrificing rigidity where the micrograin carbide substrate is most effective.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in hardened materials
• AlTiN coating for high-temperature performance and extended tool life in ferrous and stainless alloys
• 3-flute geometry balances chip evacuation with surface finish quality at small diameters
• 30-degree right-hand spiral helix promotes smooth cutting action and efficient chip flow
• Single-end ball profile with 0.0469 inch diameter for fine-detail contouring and profiling
• Miniature series long-length design at 2.5 inches OAL enables deep-cavity reach

Compatibility

Designed as an OEM-style replacement or direct-fit option for miniature ball end mill applications requiring a 1/8 inch shank and 0.0469 inch ball diameter in standard collet toolholding systems.

Installation Notes

Installation should be performed by a qualified machinist familiar with CNC or manual mill toolholding procedures. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the 1/8 inch shank fully into a clean, undamaged collet or chuck and torque the drawbar or collet nut to the toolholder manufacturer specification. Verify runout at the cutting tip before beginning a production run, as runout tolerances are critical at this diameter.
