Accupro 12185377 Ball End Mill 0.375 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12185377 is a solid carbide ball end mill designed for high-performance milling in a wide range of materials. With a 0.375 inch mill diameter and a 0.5 inch length of cut, this tool delivers accurate ball-nose profiling and contouring in both roughing and finishing passes. The 4-flute geometry with a 40-degree helix angle improves chip evacuation and surface finish quality. A TiCN coating adds hardness and thermal resistance, extending tool life in ferrous and non-ferrous applications. Machining professionals in job shops, tool rooms, and production environments use this end mill where consistent profile accuracy and tool longevity are required.

This end mill is suited for CNC milling operations requiring ball-nose geometry in materials such as alloy steels, stainless steels, aluminum, and similar workpieces. The double-end configuration provides two usable cutting ends, maximizing value per tool. The 3/8 inch shank diameter fits standard ER and end mill holders commonly used on vertical and horizontal machining centers. The stub-length classification makes it a stable choice for shorter-reach applications where rigidity is a priority.

Key Features

• 0.375 inch ball nose diameter for precise profiling and contouring
• 4-flute spiral geometry with 40-degree helix for improved chip flow and surface finish
• TiCN coating for enhanced hardness and wear resistance
• Double-end design provides two cutting ends per tool
• Solid carbide construction delivers rigidity and heat resistance
• Stub-length classification for maximum tool stability in short-reach setups

Compatibility

Designed for use in standard 3/8 inch end mill holders and ER collet chucks on CNC vertical and horizontal machining centers. Right-hand cut and right-hand flute direction; confirm spindle rotation before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the controller is in a safe state before changing tooling. Seat the 3/8 inch shank fully into the tool holder and torque the retention mechanism per the holder manufacturer specification. Inspect the cutting edges for chips or coating damage before mounting; a damaged cutting edge can affect surface finish and dimensional accuracy.
