Sandvik Coromant 8038709 Square End Mill 5/8 in Solid Carbide

Product Description

The SANDVIK COROMANT 8038709 is a solid carbide square end mill engineered for high-performance milling in metalworking and machining applications. With a 5/8 inch mill diameter and a 3/4 inch length of cut, this single-end tool delivers precise material removal across a range of workpiece materials. The ZrN (zirconium nitride) coating improves surface hardness and wear resistance, extending tool life in demanding cutting conditions. The 35-degree variable helix and variable index geometry reduce harmonic vibration during cutting, producing improved surface finishes and more consistent chip evacuation. Machinists and CNC operators working in production or job-shop environments will find this tool suitable for applications requiring tight tolerances and stable cutting performance.

The 8038709 belongs to the CoroMill Dura series and is intended for use in CNC machining centers and milling machines. It is well suited for slotting, peripheral milling, and profiling operations on non-ferrous metals and other materials within the N1BZ material grade classification. The 5/8 inch shank diameter matches standard collet and end mill holder sizes commonly found in light to medium milling setups. With a 4 inch overall length and no extended reach, this tool is designed for standard-reach applications where rigidity is a priority.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision milling
• ZrN coating enhances hardness and reduces tool wear in extended operations
• Variable helix and variable index geometry minimize vibration and chatter
• 3 flutes with right-hand cutting and right-hand flute direction for efficient chip removal
• Centercutting design allows plunge milling capability
• CoroMill Dura series rated for N1BZ material grade applications

Compatibility

Designed as an OEM-specification tool within the SANDVIK COROMANT CoroMill Dura series, compatible with standard 5/8 inch collets and end mill holders on CNC milling machines and machining centers.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from its holder. Use a torque wrench and the holder manufacturer's specified procedure when securing collet nuts to prevent runout. Inspect the tool shank and cutting edges for damage before each use, and confirm the holder bore is clean and free of chips or debris prior to seating the tool.
