Accupro 14915610 Barrel Cutter End Mill 4 Flute Altin+

Product Description

The ACCUPRO 14915610 is a solid carbide barrel cutter end mill with a lens form end geometry, designed for high-efficiency 5-axis and multi-axis CNC machining operations. The lens form profile allows for larger effective cutting radii compared to standard ball nose tools, enabling smoother surface finishes with fewer passes. Coated with AlTiN+ for elevated heat resistance and extended tool life in hardened steels, stainless alloys, and titanium. The 4-flute configuration provides a strong core with good chip evacuation. This tool is installed and operated by machinists and CNC tooling specialists in production and job shop environments.

This end mill suits applications in aerospace, die and mold, and precision component machining where contoured surface finishing is required. The lens form geometry is particularly effective for finishing curved and ramped surfaces in multi-axis setups. With a 5/8 inch shank diameter and 3.5 inch overall length, it fits standard collet and toolholder systems used on vertical and horizontal machining centers. The 11/16 inch length of cut accommodates typical finishing depths on complex contoured workpieces.

Key Features

• Lens form barrel geometry enables large effective cutting radius for superior surface finish on contoured profiles
• AlTiN+ coating provides high hardness and thermal resistance for demanding alloy and hardened material applications
• Solid carbide construction delivers rigidity and dimensional stability at elevated cutting speeds
• 4-flute design balances core strength with efficient chip removal
• 5/8 inch shank diameter fits standard precision collets and shrink-fit toolholders

Compatibility

Designed for use in standard 5/8 inch collet chucks, hydraulic toolholders, and shrink-fit toolholders on CNC machining centers requiring lens form barrel cutter geometry.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Verify collet or toolholder runout is within acceptable tolerance before beginning a cutting operation, as excessive runout accelerates wear on carbide tooling. Follow the toolholder manufacturer torque specifications for pull stud and collet nut retention.
