Accupro 12184756 Ball End Mill 0.1772 in 4 Flute Carbide

Product Description

The ACCUPRO 12184756 is a 4-flute solid carbide ball end mill designed for precision milling in metal and hard material applications. With a 0.1772-inch (4.50 mm) cutting diameter and a 0.374-inch (9.50 mm) length of cut, this stub-length end mill is built for rigidity and accurate profile work in tight-tolerance jobs. The AlTiN coating provides high heat resistance and extended tool life when cutting ferrous metals, hardened steels, and alloy materials. Right-hand cut and right-hand spiral flutes with a 40-degree helix angle promote efficient chip evacuation and a smooth cutting action. Micrograin carbide substrate supports the sharp edge retention needed for fine finish passes and contour work.

This end mill is suited for CNC machining centers and manual mills in job shops, tool rooms, and production environments. Its stub length and single-end configuration make it well-suited for applications where overhang must be minimized to control deflection, such as die and mold work, slot milling, and 3D contouring in hardened or abrasive materials. The 6 mm (0.2362-inch) shank diameter fits standard ER collet chucks and end mill holders common in most shop setups.

Key Features

• 0.1772-inch (4.50 mm) ball nose cutting diameter for precise radius profiles
• AlTiN coating for elevated heat resistance and extended tool life in ferrous and hardened materials
• Micrograin solid carbide substrate for sharp edge retention and wear resistance
• 40-degree helix angle with right-hand spiral flutes for efficient chip evacuation
• Stub length design minimizes deflection in tight-clearance and deep-pocket applications
• Single-end configuration with 6 mm shank diameter for compatibility with standard collet systems

Compatibility

Designed for use in CNC machining centers and manual mills equipped with standard ER collet chucks or end mill holders accepting a 6 mm shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully in the collet or holder to the recommended grip length before tightening to avoid runout. Verify spindle speed and feed rate parameters against the material being cut before initiating a toolpath. Inspect the cutting edge for chips or wear before each use and replace the tool if edge integrity is compromised.
