Accupro 14915663 Barrel Cutter End Mill Oval Form 4 Fl

Product Description

The ACCUPRO 14915663 is a solid carbide barrel cutter end mill with an oval form end type, designed for high-performance milling operations where complex contoured surfaces and 5-axis machining strategies are required. It features an AlTiN+ coating that provides elevated heat resistance and extended tool life in hard and abrasive materials. With a 0.75-inch shank diameter, a 1.6519-inch length of cut, and a 4-inch overall length, this end mill fits standard toolholding systems used in CNC machining centers. It is suited for machinists and tooling professionals working in aerospace, die-mold, and precision component manufacturing.

The 14915663 is applied in CNC milling operations where barrel or lens-shaped cutting geometries are used to reduce stepover and improve surface finish on curved or sculpted workpiece profiles. The oval form geometry allows for higher radial engagement on contoured surfaces compared to standard ball-nose end mills, making it a practical choice for finishing and semi-finishing passes on complex 3D geometry. The 4-flute configuration balances chip evacuation and surface finish in a range of workpiece materials.

Key Features

• Oval form barrel geometry reduces stepover on contoured surfaces for improved surface finish
• AlTiN+ finish coating provides heat resistance and wear resistance in hard and abrasive materials
• Solid carbide construction delivers rigidity and dimensional stability under cutting loads
• 4-flute design balances chip clearance and finish quality
• 0.75-inch shank diameter fits standard ER and hydraulic toolholders used in CNC machining centers
• 1.6519-inch length of cut supports reach requirements for die-mold and 5-axis finishing applications

Compatibility

Designed as an OEM-style replacement barrel cutter end mill for CNC machining centers accepting a 0.75-inch shank diameter toolholder.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom personnel. Seat the shank fully into a clean, debris-free toolholder and tighten to the toolholder manufacturer's specification using calibrated tooling. Inspect the cutting edge for chips or coating damage before mounting. Confirm runout with a dial indicator before beginning the first cut to ensure dimensional accuracy and tool life.
