Accupro 14915608 Barrel Cutter End Mill 3/8 Inch Shank

Product Description

The ACCUPRO 14915608 is a solid carbide barrel cutter end mill with a lens form end geometry, designed for high-efficiency finishing and semi-finishing operations in metalworking applications. It features an AlTiN+ finish coating that provides elevated heat resistance and extended tool life when cutting hardened steels, stainless alloys, and other difficult-to-machine materials. The 4-flute configuration promotes smooth chip evacuation while maintaining surface finish quality. With a 3/8 inch shank diameter and a 7/16 inch length of cut, this tool is suited for CNC milling machines operated by skilled machinists in production and job shop environments.

This end mill is intended for use in CNC machining centers where contoured surface finishing, 5-axis milling, and complex geometry work are required. The lens form barrel profile allows the tool to engage workpiece surfaces at a larger effective radius than a standard ball end mill, reducing the number of passes needed to achieve fine surface finishes on molds, dies, aerospace components, and similar precision parts. It is handled by machinists and CNC programmers working in both prototype and production settings.

Key Features

• Lens form barrel geometry enables large effective cutting radius for superior surface finish
• Solid carbide construction provides rigidity and wear resistance in demanding cuts
• AlTiN+ coating improves thermal resistance and tool longevity in ferrous and hardened materials
• 4-flute design balances chip clearance with cutting stability
• 3/8 inch shank diameter compatible with standard ER and hydraulic collet toolholders
• Compact 2-1/2 inch overall length supports rigidity in close-clearance setups

Compatibility

Designed as a direct-fit replacement-style solid carbide end mill for CNC milling machines and machining centers accepting 3/8 inch shank toolholders.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool changer is disabled before inserting or removing the tool from its holder. Use a calibrated torque wrench and the collet nut specified by the toolholder manufacturer to avoid under- or over-tightening. Verify runout with a dial indicator before initiating a cutting program to protect both the tool and the workpiece.
