Accupro 14915617 Barrel Cutter End Mill Taper Form Altin+

Product Description

The ACCUPRO 14915617 is a solid carbide barrel cutter end mill configured in a taper form geometry for 5-axis and multi-axis CNC machining operations. It carries a 15-degree taper angle per side and a small end diameter of 0.625 inches, generating a large effective radius contact path that reduces scallop height and allows faster feed rates compared to ball end mills. The AlTiN+ finish coating provides high-temperature hardness and oxidation resistance, extending tool life in ferrous and hardened materials. With a 4-flute configuration and a 0.9834-inch length of cut, this end mill suits finishing and semi-finishing passes on complex contoured surfaces in aerospace, mold, and die applications.

This end mill is used in CNC machining centers running 5-axis or 3+2 strategies on hardened steels, stainless steels, titanium, and similar difficult-to-machine materials. Typical applications include finishing curved or sculpted surfaces on molds, dies, turbine components, and structural aerospace parts. The barrel form geometry allows the tool to engage at a tilted angle, producing smooth surface finishes with fewer passes. The 5/8-inch shank fits standard collet and end mill holders common in vertical and horizontal machining centers.

Key Features

• Taper form barrel geometry with 15-degree taper angle per side reduces scallop height on contoured surfaces
• Solid carbide construction provides rigidity and wear resistance for hardened and abrasive workpieces
• AlTiN+ coating delivers thermal stability and oxidation resistance at elevated cutting temperatures
• 4-flute design supports aggressive material removal rates on finishing passes
• 0.9834-inch length of cut accommodates shallow to moderate depth contour work
• 5/8-inch shank diameter compatible with standard CNC collet chucks and end mill holders

Compatibility

Designed for use in CNC machining centers accepting a 5/8-inch shank end mill; suited for 5-axis and 3+2 multi-axis toolpath strategies on hardened and difficult-to-machine materials.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading the tool. Seat the shank fully in the holder and torque the retention mechanism to the holder specification. Verify runout with a dial indicator before initiating a cutting program, as excessive runout will accelerate wear on a carbide tool.
