Accupro 14915667 Oval Form Barrel Cutter End Mill 6 Flute

Product Description

The ACCUPRO 14915667 is a solid carbide oval form barrel cutter end mill designed for high-performance 5-axis and multi-axis machining operations. The oval barrel profile generates a large effective cutting radius on the tool flank, allowing aggressive step-overs while maintaining a fine surface finish — a significant advantage over traditional ball end mills in complex contouring work. The AlTiN+ finish coating provides excellent thermal resistance and hardness at elevated cutting temperatures, extending tool life in ferrous materials, hardened steels, and heat-resistant alloys. With a 0.75 inch small end diameter and 6 flutes, this tool is built for rigidity and high chip-load efficiency in demanding production environments.

This barrel cutter is suited for aerospace, die and mold, and precision part manufacturing where 3D surface finishing is required. It is typically run on CNC machining centers equipped for simultaneous 5-axis motion. The 6-flute configuration supports high-feed finishing passes on hardened tool steels, titanium alloys, and nickel-based superalloys. The 0.75 inch shank diameter ensures a stable grip in standard end mill holders, collet chucks, or hydraulic toolholders. It is installed and operated by CNC machinists and tool-and-die professionals working in shops with multi-axis capability.

Key Features

• Oval form barrel profile enables large effective cutting radius for fine surface finishes with reduced cycle time
• Solid carbide construction provides rigidity and vibration resistance in demanding cutting conditions
• AlTiN+ coating delivers high heat resistance and extended tool life in ferrous and exotic alloys
• 6-flute design supports high chip loads and smooth surface finishes on finishing passes
• 1.6519 inch length of cut accommodates deep contouring passes in complex workpiece geometry
• 0.75 inch shank diameter fits standard end mill holders and collet chucks on most CNC platforms

Compatibility

Designed for use in CNC machining centers with standard 0.75 inch end mill holders, collet chucks, or hydraulic toolholders capable of 5-axis or multi-axis motion. No specific machine model compatibility was provided in the product data.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before loading or changing tooling. Seat the shank fully into the holder to the minimum engagement depth recommended by the holder manufacturer and torque the retention hardware according to the holder specification. Verify runout at the tool tip with a dial indicator before beginning a production run, as excessive runout on a barrel cutter will directly affect surface finish quality.
