Accupro 12179222 Ball End Mill 0.1719 in 4 Flute Carbide

Product Description

The ACCUPRO 12179222 is a solid carbide ball end mill designed for precision milling operations in metal cutting and machining applications. With a 0.1719-inch cutting diameter and four right-hand spiral flutes, it delivers efficient chip evacuation and a smooth finish on contoured and profiled surfaces. The 40-degree helix angle promotes aggressive yet controlled cutting action across a range of ferrous and non-ferrous materials. A nACRo (nanocomposite aluminum-chromium) coating extends tool life by reducing heat buildup and wear at the cutting edge. This end mill is intended for use by machinists and tool-and-die professionals working on CNC mills and manual milling machines.

This end mill is suited for profiling, contouring, slotting, and finish milling in die and mold work, aerospace components, and precision part manufacturing. Its small diameter makes it appropriate for detailed cavity work and tight-radius features. The single-end configuration and 0.625-inch length of cut allow access to moderate-depth features while the 3/16-inch shank accommodates standard collets and end mill holders on most machining centers and knee mills.

Key Features

• 0.1719-inch (11/64 inch) ball-nose cutting diameter for small-radius profiling and contouring
• 4 right-hand spiral flutes with 40-degree helix angle for efficient chip removal
• Solid micrograin carbide construction for rigidity and extended tool life in hardened materials
• nACRo coating reduces friction and thermal wear, improving performance in difficult-to-machine alloys
• Single-end design with 0.625-inch length of cut and 2-inch overall length
• Mill diameter tolerance of +0.000 to -0.002 inches for consistent fit in precision work

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills using 3/16-inch collets or end mill holders. Compatible with standard right-hand spindle setups.

Installation Notes

Installation should be performed by a qualified machinist following standard tooling procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in the collet or holder and torque the drawbar or collet nut per the machine manufacturer specifications. Verify runout with a dial indicator before beginning a cut, particularly given the close diameter tolerances on this tool.
