Accupro 12184807 Ball End Mill 0.3594 in 4 Flute Carbide

Product Description

The ACCUPRO 12184807 is a single-end ball end mill engineered for precision contouring, profiling, and 3D milling operations on hardened and abrasive materials. Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for demanding CNC machining applications. The mill measures 0.3594 inches in diameter with a 0.625-inch length of cut and a 2-inch overall length. An AlTiN coating provides high-temperature oxidation resistance and reduced friction, extending tool life in ferrous and hardened steel applications. Four spiral flutes with a 40-degree right-hand helix promote efficient chip evacuation and a smooth finish.

This end mill is suited for use in CNC machining centers handling die and mold work, finishing passes on hardened steels, and contour milling of complex 3D profiles in both job shop and production environments. The stub-length geometry and 3/8-inch shank diameter make it compatible with standard collet chucks and end mill holders commonly found in vertical and horizontal machining centers. It is a go-to choice for machinists requiring tight tolerances on hardened or abrasive workpiece materials.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• AlTiN coating resists oxidation and reduces friction at elevated cutting temperatures
• 40-degree right-hand helix improves chip evacuation and surface finish quality
• 4-flute spiral configuration balances rigidity with cutting efficiency
• Stub-length design minimizes deflection for tighter tolerances
• Single-end geometry; right-hand cutting direction

Compatibility

Designed as a direct-fit replacement or standard tooling option for CNC machining centers and manual mills equipped with 3/8-inch collet chucks or end mill holders accepting a 3/8-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the spindle before mounting or removing the tool. Seat the shank fully into the collet or holder to the recommended minimum engagement depth before torquing the retention hardware. Inspect the cutting edges for chips or wear before each use and confirm runout with a dial indicator when tolerances are critical.
