Sandvik Coromant 8037559 Square End Mill 3/8 in 3 Flute Carbide

Product Description

The SANDVIK COROMANT 8037559 is a solid carbide square end mill designed for high-performance milling in demanding machining environments. Built to the CoroMill Dura series standard, it features a 3/8 inch cutting diameter and a 1 inch length of cut, supported by three flutes with a 35-degree variable helix and variable index geometry. The ZrN (zirconium nitride) coating reduces friction and extends tool life in non-ferrous and finishing applications. The right-hand cutting and right-hand flute direction make this a standard configuration for conventional CNC milling setups. This tool is installed and operated by machinists and CNC programmers working in job shops, production facilities, and tool rooms.

This end mill suits light to medium milling operations on non-ferrous materials, as indicated by the N1BZ material grade designation. The 3/8 inch shank diameter matches the cutting diameter for straightforward tool holding, and the 2.5 inch overall length keeps the tool compact for rigidity in tight setups. The centercutting capability allows plunge entry, expanding application flexibility for slotting, profiling, and pocket milling operations.

Key Features

• 3/8 inch cutting diameter with 1 inch length of cut for short-reach milling operations
• Variable helix and variable index geometry reduces harmonics and chatter during cut
• ZrN coating improves wear resistance and surface finish on non-ferrous materials
• Centercutting design enables direct plunge entry without pre-drilling
• Solid carbide construction provides rigidity and dimensional stability at elevated cutting speeds
• Right-hand cut, right-hand flute — compatible with standard CNC mill spindle rotation

Compatibility

Part of the SANDVIK COROMANT CoroMill Dura series, designed for use with standard 3/8 inch tool holders and collet chucks on CNC machining centers and manual milling machines. Material grade N1BZ targets non-ferrous workpiece materials.

Installation Notes

Installation is performed by a machinist or CNC setup technician. The spindle must be fully stopped and the machine placed in an e-stop or lockout state before changing tooling. Use a properly sized collet or end mill holder rated for 3/8 inch shank diameter and torque the retention mechanism per the tool holder manufacturer specification. Verify runout with a dial indicator before initiating a cut to protect both the tool and the workpiece.
