Accupro 12184108 Ball End Mill 0.1875 in 2 Flute Carbide

Product Description

The ACCUPRO 12184108 is a solid carbide ball end mill designed for precision milling operations in ferrous and hard materials. With a 0.1875-inch (3/16-inch) diameter and a 0.375-inch length of cut, this single-end tool is built for contour milling, profiling, and finishing passes where a spherical cutting edge is required. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. An AlTiN coating increases surface hardness and heat resistance, making the tool well suited to high-speed dry cutting and hard-material applications. Machinists and tool and die technicians rely on this geometry for tight-tolerance 3D surface work.

This end mill is used in CNC machining centers and manual mills for applications including die and mold work, contour profiling, slot milling, and finish passes on hardened steels and alloy materials. The stub-length configuration provides added rigidity, reducing deflection in demanding cuts. Its right-hand cutting and right-hand flute direction are standard for conventional CNC setups. The 0.1875-inch shank diameter matches standard collets and tool holders used across typical machining centers.

Key Features

• 0.1875-inch ball nose diameter for spherical contour and profile milling
• AlTiN coating for improved heat resistance and tool life in hard and ferrous materials
• 40-degree helix angle promotes chip evacuation and reduces cutting forces
• Micrograin solid carbide construction for wear resistance and edge stability
• Stub-length design increases rigidity and minimizes deflection
• Single-end, right-hand cut with spiral flute geometry

Compatibility

Designed as an OEM-style replacement and standard tooling option compatible with CNC machining centers and manual milling machines accepting a 3/16-inch shank diameter collet or tool holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is powered down or in a safe state before changing tooling. Seat the shank fully into the collet or tool holder and torque the retention hardware to the machine manufacturer's specification. Verify runout with a dial indicator before beginning a cut, particularly for finish-pass applications where dimensional accuracy is critical.
