Accupro 14915607 Barrel Cutter End Mill Lens Form Altin+

Product Description

The ACCUPRO 14915607 is a solid carbide barrel cutter end mill with a lens form end geometry, designed for high-efficiency multi-axis CNC machining operations. The lens form profile allows for a larger effective cutting radius compared to standard ball nose tools, enabling greater stepover distances and improved surface finish with fewer passes. Coated with AlTiN+, the tool provides elevated heat resistance and extended tool life in hard and abrasive workpiece materials. The 3/4 inch shank diameter and 4 inch overall length suit it for use in rigid setups requiring reach and stability. Three flutes balance chip evacuation with cutting performance in finishing and semi-finishing applications.

This end mill is suited for 5-axis and multi-axis CNC machining centers used in aerospace, die and mold, and precision component manufacturing environments. The lens form geometry is particularly effective for scallop-reduction finishing passes on complex contoured surfaces. Typical users include CNC machinists and programmers running hardened steels, titanium alloys, and high-temperature alloys where surface integrity is critical. The 13/16 inch length of cut provides adequate engagement depth for most contour-finishing tool paths without sacrificing rigidity.

Key Features

• Lens form barrel geometry reduces scallop height and allows larger stepovers on contoured surfaces
• Solid carbide construction provides rigidity and dimensional stability under high cutting forces
• AlTiN+ coating delivers high-temperature oxidation resistance and extended tool life in hard materials
• 3/4 inch shank diameter supports secure toolholder engagement and minimizes runout
• 3-flute design balances chip clearance with cutting efficiency in finishing operations
• 13/16 inch length of cut compatible with standard contour-finishing and scallop-reduction tool paths

Compatibility

Designed for use in CNC machining centers with 3/4 inch collet or hydraulic toolholders. No specific machine model or system compatibility was stated in the product data.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Ensure the spindle is fully powered down and the machine is in an E-stop or tool-change state before loading or unloading the tool. Use a calibrated toolholder with the appropriate bore size to achieve proper runout tolerances. Verify tool projection and length offset in the CNC controller before initiating any cutting operation.
