Accupro 14915662 Oval Form Barrel Cutter End Mill

Product Description

The ACCUPRO 14915662 is a solid carbide oval form barrel cutter end mill engineered for high-efficiency finishing and semi-finishing operations on complex contoured surfaces. The oval barrel geometry reduces the number of passes required to achieve smooth surface finishes on 3D and multi-axis machined parts. Coated with AlTiN+ for enhanced heat resistance and tool life at elevated cutting speeds, this end mill features a 4-flute configuration and a 0.625-inch small end diameter, making it well suited to demanding mold, die, and aerospace component work.

This barrel cutter is used in applications where conventional ball end mills would require excessive step-over passes to meet surface finish requirements. It is particularly effective on turbine blades, impellers, mold cavities, and other complex freeform geometries machined on 4-axis and 5-axis CNC machining centers. The oval form tip geometry provides a large effective radius of curvature, enabling wider step-over without degrading surface finish. Machinists and toolmakers in precision manufacturing environments are the primary users of this tool.

Key Features

• Solid carbide construction provides rigidity and wear resistance in hard and abrasive materials
• AlTiN+ coating delivers high-temperature oxidation resistance for dry or high-speed machining
• Oval form barrel geometry enables wide step-over on 3D contoured surfaces, reducing cycle time
• 4-flute design balances chip evacuation and feed rate capability
• 1.3766-inch length of cut accommodates medium-depth finishing passes on complex features
• 5/8-inch shank diameter compatible with standard ER and hydraulic toolholders

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide barrel end mill for CNC machining centers accepting a 5/8-inch shank diameter toolholder.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool change protocol is engaged before mounting or removing the end mill. Use a properly sized collet or toolholder to achieve correct runout within machine and tooling manufacturer tolerances. Inspect the cutting edges and coating condition before each use and replace the tool at the first sign of chipping or excessive wear to avoid workpiece damage.
