Sandvik Coromant 8036783 Corner Radius End Mill

Product Description

The SANDVIK COROMANT 8036783 is a solid carbide corner radius end mill from the CoroMill Dura series, designed for high-performance milling in demanding metalworking applications. It features a 3/8 inch cutting diameter, 0.015 inch corner radius, and five flutes with a variable helix and variable index geometry. The AlTiN coating provides heat and wear resistance for dry or semi-dry machining. This end mill is single-end and centercutting, making it suitable for plunge entries and complex toolpaths. Licensed machinists and CNC operators working in production or job-shop environments are the typical end users.

This end mill is well suited for side milling, slotting, and contouring operations in steel, stainless steel, and high-temperature alloys where edge stability and surface finish are critical. The variable helix design reduces chatter and harmonics during cut. It fits standard 3/8 inch collet or milling chuck toolholding systems and is sized for vertical machining centers and CNC mills handling precision component work in aerospace, mold, and die, and general metal fabrication.

Key Features

• 5-flute variable helix geometry reduces vibration and improves surface finish
• Variable index spacing minimizes harmonic chatter at higher feed rates
• AlTiN coating extends tool life in dry and semi-dry high-heat cutting conditions
• 0.015 inch corner radius protects the cutting edge and improves part corner durability
• Centercutting design allows plunge milling and ramp entry without a pre-drilled hole
• Solid carbide construction from CoroMill Dura series material grade X1BH delivers rigidity and wear resistance

Compatibility

Designed for use in standard 3/8 inch straight-cylindrical shank toolholding systems including collet chucks and milling holders on CNC vertical and horizontal machining centers. Compatible with right-hand spindle rotation and right-hand flute direction setups.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully powered down and the tool carousel or holder is secured before changing tooling. Use a properly sized collet or milling chuck torqued to the toolholder specification to prevent pullout under load. Confirm runout with a dial indicator before initiating the first cut, particularly given the tight corner radius tolerance on this end mill.
