Accupro 14915650 Taper Form Barrel Cutter End Mill

Product Description

The ACCUPRO 14915650 is a taper form barrel cutter end mill ground from solid carbide and coated with AlTiN+ for extended tool life in demanding cutting applications. It features a 30-degree taper angle per side, a 6-flute geometry that promotes chip evacuation and surface finish quality, and a 3/4-inch shank diameter for rigid workholding in standard toolholders. The length of cut is 0.6562 inches with an overall length of 4 inches. The AlTiN+ coating provides high oxidation resistance and hardness retention at elevated cutting temperatures, making this tool well suited for dry or near-dry machining strategies in hardened and abrasive materials.

This end mill is intended for CNC milling operations where taper form or barrel-style cutting paths are programmed, typically in five-axis or 3+2 setups used in die and mold work, aerospace component finishing, and precision part contouring. The barrel profile reduces contact arc compared to a ball end mill, allowing faster feed rates and improved surface finish in finishing passes on curved or inclined surfaces. Machinists and CNC programmers in job shops, production facilities, and tool rooms are the primary users of this geometry.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials
• AlTiN+ finish coating delivers high oxidation resistance and thermal hardness retention for dry and high-speed cutting
• 30-degree taper angle per side enables aggressive barrel-form toolpaths on inclined and contoured surfaces
• 6-flute design supports higher feed rates and improved surface finish in finishing operations
• 3/4-inch shank diameter provides compatibility with standard ER, hydraulic, and shrink-fit toolholders
• 4-inch overall length accommodates reach requirements in deep-cavity and multi-axis setups

Compatibility

Designed for use in CNC machining centers with standard 3/4-inch toolholding systems. No specific machine model compatibility data was provided by the manufacturer for this part number.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool changer is disabled before inserting or removing the end mill from its holder. Use the appropriate torque when tightening collet nuts or set screws per the toolholder manufacturer specifications. Verify runout after installation and confirm toolpath programming matches the taper angle and cutting diameter parameters of this tool geometry before initiating a cut.
