Accupro 12184927 Ball End Mill 0.125 in 4 Flute Carbide

Product Description

The ACCUPRO 12184927 is a single-end ball end mill designed for precision milling of contoured surfaces, pockets, and 3D profiles in ferrous and non-ferrous materials. Built from micrograin solid carbide, it delivers the hardness and edge integrity required for high-speed cutting in demanding shop environments. The 0.125-inch diameter cutting head, 4-flute geometry, and 40-degree right-hand helix work together to balance chip evacuation with surface finish quality. An AlTiN coating provides thermal resistance and extended tool life at elevated cutting temperatures. This tool is installed and operated by machinists and CNC programmers on vertical and horizontal machining centers.

This end mill is suited for finish and semi-finish milling passes on die and mold work, aerospace components, and precision mechanical parts where tight tolerances on curved or sloped surfaces are required. The long 0.75-inch length of cut and 3.0-inch overall length support reach into deeper cavities without requiring extended-reach toolholders. The 0.125-inch shank diameter fits standard collet systems and shrink-fit holders sized for 1/8-inch tooling.

Key Features

• 0.125-inch ball nose diameter for fine contouring and small-radius profiling
• 4-flute spiral geometry with 40-degree right-hand helix for balanced chip removal and surface finish
• Micrograin solid carbide substrate for hardness and edge stability
• AlTiN coating for high heat resistance and extended tool life in ferrous materials
• 0.75-inch length of cut and 3.0-inch overall length for extended reach into deep features
• Single-end construction with 0.125-inch shank for compatibility with standard collet systems

Compatibility

Designed as an OEM-style replacement or standard production tooling for CNC machining centers and manual mills equipped with collet holders or shrink-fit systems accepting a 0.125-inch shank diameter.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer or collet is properly torqued before beginning a cutting program. Verify runout at the tool tip using a dial indicator before commencing finish passes. Follow shop-specific speeds and feeds for the workpiece material and observe all applicable machine guarding requirements.
