Accupro 12184744 Ball End Mill 0.1406 in 4 Flute Carbide

Product Description

The ACCUPRO 12184744 is a solid carbide ball end mill designed for precision milling operations in ferrous and hardened materials. Built from micrograin solid carbide, it delivers rigidity and wear resistance in demanding cutting environments. The 0.1406-inch diameter cutting end is suited for fine detail work, profiling, and contouring. An AlTiN coating provides thermal barrier protection and extended tool life at elevated cutting speeds. With four flutes and a 40-degree right-hand helix, the tool generates a smooth, efficient chip load for high-feed finishing passes. This end mill is installed and operated by machinists and CNC tooling professionals in production and job-shop environments.

This tool is used in CNC milling centers and manual mills for small-diameter slotting, profiling, 3D contouring, and die-and-mold work. The stub-length configuration and 0.375-inch length of cut make it well-suited for applications requiring high rigidity with minimal deflection. The 3/16-inch shank diameter fits standard ER collets and toolholders sized for that diameter. It is a single-end tool intended for right-hand cutting direction in typical vertical or horizontal mill setups.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention in hard materials
• AlTiN coating for thermal resistance and extended tool life at high cutting speeds
• 4-flute, 40-degree right-hand helix for efficient chip evacuation and smooth surface finish
• 0.1406-inch ball end diameter for fine contouring and detail profiling passes
• Stub-length design minimizes deflection in tight-tolerance machining operations
• Single-end configuration with right-hand cutting direction for standard CNC and manual mill use

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 3/16-inch shank diameter in ER collets or matching toolholders.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. The machine spindle must be at a full stop before inserting or removing the tool from the collet or toolholder. Verify collet bore matches the 3/16-inch shank diameter before clamping to the manufacturer-specified torque using appropriate collet wrenches. Inspect the cutting edge for chips or coating damage before each use and confirm runout is within acceptable tolerance for the application.
