Iscar 3399010 Square End Mill 5/8 in 3 Flute Carbide Dlc

Product Description

The ISCAR 3399010 is a solid carbide square end mill designed for precision metal removal in milling operations. Built from submicron carbide and finished with a DLC (Diamond-Like Carbon) coating, this end mill delivers high wear resistance and reduced friction during cutting. It features a 5/8 inch diameter, a 2 inch length of cut, and a 45-degree helix angle that promotes efficient chip evacuation. The variable index geometry helps reduce harmonic vibration, making it well suited for demanding milling applications. Machinists and CNC operators working in job shops, tool rooms, and production environments are the primary installers and users of this tool.

This end mill is suited for use on CNC machining centers and manual mills where high-performance material removal is required. The 3-flute configuration balances chip clearance and tool rigidity, making it effective for slotting, peripheral milling, and profiling in ferrous and non-ferrous materials. The DLC coating is particularly advantageous in applications involving aluminum, composites, and other materials where built-up edge is a concern. The 5/8 inch shank diameter provides a secure, consistent grip in standard collets and end mill holders.

Key Features

• 5/8 inch cutting diameter with 2 inch length of cut for deep slot and profile work
• DLC coating reduces friction and extends tool life in non-ferrous and composite materials
• 45-degree right-hand helix promotes aggressive chip evacuation and smooth cutting action
• Variable index flute spacing reduces vibration and chatter during high-feed operations
• Submicron solid carbide construction provides superior hardness and edge retention
• Center-cutting capable for direct plunge entry without a pilot hole

Compatibility

Designed as a direct-fit replacement for applications requiring a 5/8 inch shank, single-end square end mill in standard collet chucks and end mill holders on CNC and manual milling machines.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Ensure the spindle is fully powered down and locked before changing tooling. Seat the shank fully into the collet or holder and torque the retention mechanism according to the holder manufacturer specifications. Inspect the collet for wear or runout before use, as excessive runout accelerates edge wear on solid carbide tools.
