Accupro 14788694 Ball End Mill 0.219 in 4 Flute Carbide

Product Description

The ACCUPRO 14788694 is a solid carbide ball end mill designed for precision milling of contoured surfaces, slots, and complex 3D profiles in ferrous and non-ferrous materials. With a 0.219-inch cutting diameter and a 0.375-inch length of cut, this tool delivers consistent performance in tight-tolerance machining operations. The AlTiN+ coating provides elevated heat resistance and extended tool life in high-speed applications. Four medium flutes balance chip evacuation with cutting edge strength, making this mill a reliable choice for machinists running CNC machining centers in job shops and production environments.

This ball end mill is suited for finish and semi-finish milling passes on hardened steels, alloy steels, stainless steels, and similar materials where surface finish and dimensional accuracy are critical. The 0.25-inch cylindrical shank fits standard collet chucks and end mill holders commonly found on vertical and horizontal machining centers. The compact 2-inch overall length keeps the tool rigid in shallow-to-moderate reach applications, reducing deflection and chatter during cut.

Key Features

• AlTiN+ coating improves heat resistance and wear life in ferrous machining
• Solid carbide construction provides rigidity and dimensional stability
• 4 medium flutes balance chip flow and cutting edge durability
• Ball nose profile enables contouring, radii, and 3D surface milling
• Cylindrical shank compatible with standard collets and end mill holders
• No chipbreaker geometry supports smooth finish passes

Compatibility

Designed for use in CNC machining centers and manual mills equipped with standard 0.25-inch collet chucks or end mill holders accepting a cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and power is off before loading or removing the tool from the holder. Verify collet or holder runout is within acceptable tolerance before beginning a cut to protect both the tool and the workpiece. Follow the machine manufacturer and tooling supplier guidelines for speeds, feeds, and depth of cut appropriate to the workpiece material.
