Accupro 14915652 Taper Form Barrel Cutter End Mill

Product Description

The ACCUPRO 14915652 is a taper form barrel cutter end mill ground from solid carbide and coated with AlTiN+ for extended tool life in hard and abrasive materials. It features a 45-degree taper angle per side and a 6-flute geometry, producing a barrel-form cutting profile well suited to contour milling and 3D surfacing operations on CNC machining centers. The shank diameter measures 3/8 inches with an overall length of 2.5 inches and a length of cut of 3/16 inches. The AlTiN+ coating raises surface hardness and thermal resistance, allowing higher cutting speeds compared to uncoated carbide tooling.

This end mill is used in precision CNC milling applications where a barrel or lens-form cutter path is required to reduce scallop height on complex 3D surfaces. It is particularly effective in aerospace, die and mold, and precision machining environments where finish quality and material removal rates on hardened steels and alloys are priorities. Machinists and CNC programmers running 5-axis or 3+2 toolpaths will find the taper form geometry directly applicable to flank milling curved surfaces.

Key Features

• Taper form barrel cutter profile reduces scallop height on 3D contour operations
• Solid carbide construction provides rigidity and wear resistance in hard materials
• AlTiN+ finish coating improves heat resistance and extends cutting tool life
• 6-flute design supports higher feed rates and improved surface finish
• 45-degree taper angle per side enables aggressive material removal on compound surfaces
• 3/8-inch shank diameter fits standard collet and end mill holders

Compatibility

Designed for use in CNC machining centers accepting a 3/8-inch shank end mill holder or collet chuck. Suitable for taper form and barrel cutter toolpaths in CAM software supporting lens or oval form cutter definitions.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the machine powered down and spindle fully stopped. Confirm holder runout with a dial indicator before running at speed, as excessive runout accelerates wear on carbide tooling. Follow the machine tool manufacturer and CAM software guidelines for feed, speed, and toolpath strategy specific to barrel cutter geometry. Secure the shank to the specified clamping torque of the tool holder manufacturer.
