Accupro 72035413 Ball End Mill 3/8 Inch 6 Flute Carbide

Product Description

The ACCUPRO 72035413 is a solid carbide ball end mill designed for high-performance milling in demanding applications. Built with six flutes and a variable helix angle of 36 to 40 degrees, it delivers smooth cutting action and reduced chatter compared to fixed-helix tools. The AlTiN+ coating provides thermal resistance and extended tool life when cutting heat-resistant and high-temperature alloys. With a 3/8 inch diameter and a 1/2 inch length of cut, this single-end mill suits finish milling and contour work in tight tolerances. CNC machinists and tool-and-die professionals working with high-temp alloys are the primary users of this tool.

This end mill is rated for primary use in high-temperature alloys, classified under workpiece material code S, which includes nickel-based superalloys, titanium, and similar difficult-to-machine materials. The variable index geometry, combined with the AlTiN+ coating, reduces harmonics and heat buildup during aggressive cuts. It fits standard 3/8 inch straight-shank collets and tool holders, making it compatible with most CNC machining centers and manual mills equipped with a matching collet system. The right-hand cutting and right-hand flute direction are the standard configuration for conventional spindle rotation.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN+ coating rated for high-temperature alloy machining
• Variable helix (36 to 40 degrees) and variable index reduce vibration and chatter
• Six-flute design improves surface finish and chip evacuation on finishing passes
• Center-cutting geometry allows plunge entry into the workpiece
• Single-end, straight shank fits standard 3/8 inch collets and end mill holders

Compatibility

Designed for use in CNC machining centers and milling machines with 3/8 inch straight-shank collet or end mill holder systems. Intended for cutting high-temperature alloys (material code S) including nickel superalloys and titanium.

Installation Notes

Install in a clean, properly sized 3/8 inch collet or end mill holder and torque the retention system according to the toolholder manufacturer specification. Inspect the shank and collet bore for chips or debris before seating the tool. Confirm spindle direction is set to right-hand rotation before engaging the cut. This tool does not support coolant-through delivery; use external coolant or air blast as appropriate for the application.
