Accupro 14915612 Barrel Cutter End Mill Altin+ 3/8 Shank

Product Description

The ACCUPRO 14915612 is a solid carbide barrel cutter end mill with a taper form end, designed for high-performance milling in demanding machining environments. It features an AlTiN+ finish coating that extends tool life by resisting heat and wear at elevated cutting temperatures. The taper angle per side is 15.00 degrees, and the tool carries four flutes for efficient chip evacuation and a smooth surface finish. With a 3/8 inch shank diameter and an overall length of 2.5 inches, this end mill fits standard ER and end mill holders used on CNC machining centers. Machinists and tooling specialists working in aerospace, die and mold, and precision part production are the primary users of this cutter geometry.

This barrel cutter is suited for 5-axis and high-feed finishing operations where a taper form geometry reduces tool overhang deflection and improves surface quality on complex contoured features. The small end diameter of 0.3750 inches and length of cut of 0.5901 inches position it well for semifinish and finish passes on steep walls, undercuts, and sculptured surfaces. It is used in job shops and production facilities running hardened steels, stainless alloys, and high-temperature superalloys where AlTiN+ coating performance is critical.

Key Features

• Solid carbide construction provides rigidity and wear resistance for hard material applications
• AlTiN+ coating delivers high oxidation resistance and extended tool life at elevated cutting speeds
• 15.00 degree taper angle per side enables barrel and taper form milling of contoured surfaces
• 4-flute design promotes efficient chip flow and consistent surface finish
• 3/8 inch shank diameter fits standard collet chucks and end mill holders
• 0.5901 inch length of cut suits semifinish and finish passes on complex geometries

Compatibility

Designed as a direct-fit replacement for taper form barrel cutter end mills requiring a 3/8 inch shank, 15.00 degree taper angle per side, and AlTiN+ coating in CNC machining center applications.

Installation Notes

Installation is performed by qualified machinists or tooling technicians on CNC milling equipment. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Use a properly torqued collet nut and a clean, undamaged holder bore to seat the shank correctly. Verify runout with a dial indicator after clamping, as excessive runout will accelerate wear on a fine-geometry cutter of this type.
