Sandvik Coromant 8036839 Square End Mill 5/8in 5 Flute

Product Description

The SANDVIK COROMANT 8036839 is a 5-flute solid carbide square end mill designed for high-performance milling in demanding metal-cutting applications. It features a 5/8-inch cutting diameter, a 3/4-inch length of cut, and a 3-inch overall length with a matching 5/8-inch shank diameter. The AlTiN coating provides heat and wear resistance, extending tool life in dry or semi-dry machining conditions. A variable helix and variable index geometry reduce chatter and harmonic vibration during aggressive side milling and slotting operations. This tool is part of the CoroMill Dura series and is suited for use by professional machinists and CNC operators working in job shops, aerospace, and precision manufacturing environments.

This end mill is built for right-hand cutting and right-hand flute direction, centercutting capable, and optimized for ferrous and hard alloy workpiece materials. The variable helix design supports both finishing and semi-finishing passes at elevated feed rates. It is typically used in CNC machining centers for profiling, contouring, and slotting operations where tool stability and surface finish consistency are required. The material grade is X1BH, indicating suitability for hardened steels and other challenging materials within the CoroMill Dura application range.

Key Features

• 5/8-inch cutting diameter with 3/4-inch length of cut for precise depth control
• 5-flute solid carbide construction for rigidity and heat resistance
• AlTiN coating for extended tool life in high-temperature cutting environments
• Variable helix and variable index geometry to suppress vibration and chatter
• Centercutting design allows plunge entry into workpiece material
• CoroMill Dura series, material grade X1BH, suited for hardened and difficult-to-machine alloys

Compatibility

Designed as an OEM-specified solid carbide end mill within the SANDVIK COROMANT CoroMill Dura series. Compatible with standard CNC tool holders accepting a 5/8-inch straight shank. No specific machine model compatibility was stated in the input data.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the tool holder is clean and free of debris before seating the shank, and confirm runout with a dial indicator before beginning production cuts. Power down and lock out the spindle before changing tooling. Follow the machine manufacturer and cutting tool manufacturer guidelines for recommended speeds, feeds, and depth of cut for the target workpiece material.
