Accupro 14915623 Taper Form Barrel Cutter End Mill

Product Description

The ACCUPRO 14915623 is a solid carbide barrel cutter end mill with a taper form end geometry, designed for high-efficiency profiling and finishing operations in CNC machining applications. This 4-flute tool features a 30-degree taper angle per side and an AlTiN+ finish coating, which provides elevated heat resistance and extended tool life in ferrous and hardened materials. The shank diameter is 0.5 inches with an overall length of 3 inches. The barrel cutter profile allows for larger effective cutting radii on curved surfaces, reducing the number of passes required during 5-axis and 3+2 machining operations. It is used by machinists and CNC programmers in precision manufacturing environments.

This end mill is suited for die and mold work, aerospace profiling, and precision part finishing where taper and contour surfaces are common. The taper form end type is applied during semi-finish and finish passes on complex geometry workpieces. The 0.4375-inch length of cut and 0.5000-inch small end diameter make this tool appropriate for moderate-depth profiling cuts in tight or angled cavity features. It is typically run on 3-axis, 3+2, or full 5-axis CNC machining centers with appropriate toolholder setups for the 1/2-inch shank diameter.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• AlTiN+ coating for high-temperature performance and extended tool life in ferrous materials
• 30-degree taper angle per side enables profiling of angled and complex contour surfaces
• 4-flute design balances material removal rate with chip evacuation on finish passes
• Barrel cutter geometry reduces stepover distance and improves surface finish on curved features
• 0.5000-inch small end diameter and 0.4375-inch length of cut suited for moderate-depth cavity work

Compatibility

Designed for use in standard 1/2-inch bore toolholders including ER collet chucks, shrink-fit holders, and hydraulic chucks on CNC machining centers capable of 3-axis, 3+2, or 5-axis operation.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and the control in a safe state. Ensure the toolholder bore and shank are clean and free of chips or burrs before seating. Confirm runout at the cutting edge with a dial indicator before starting a program, as excessive runout will reduce coating life and surface finish quality. Consult the machine manufacturer and tooling documentation for recommended speeds, feeds, and clamping torque for the specific toolholder type.
