Sandvik Coromant 8037459 Corner Radius End Mill

Product Description

The SANDVIK COROMANT 8037459 is a solid carbide corner radius end mill designed for high-performance milling in demanding metal-cutting applications. Built on the CoroMill Dura platform, it features a 1 inch cutting diameter, a 0.25 inch corner radius, and three flutes arranged in a variable-helix, variable-index configuration. This geometry reduces harmonic vibration and chatter during aggressive cuts. The bright, uncoated finish suits use with compatible cutting fluids on ferrous and non-ferrous materials. Licensed machinists and CNC programmers typically specify this tool for finishing and semi-finishing passes where edge precision and surface finish matter.

This end mill is suited for use in CNC machining centers handling medium to large workpieces where a long length of cut is required. The 3.25 inch length of cut and 6 inch overall length make it practical for deep-pocket and deep-wall milling operations. The straight cylindrical shank measures 1 inch in diameter, compatible with standard ER and hydraulic toolholders at that bore size. Single-end configuration and centercutting capability allow plunge entry without a pre-drilled pilot hole.

Key Features

• Variable helix and variable index geometry reduces chatter and improves surface finish in demanding cuts
• 0.25 inch corner radius provides edge strength and reduces stress concentration at part corners
• Solid carbide construction in H10F grade for wear resistance in hard and abrasive materials
• 3.25 inch length of cut supports deep-pocket and deep-wall milling operations
• Centercutting design enables direct plunge entry without a pilot hole
• Right-hand flute direction and right-hand cutting for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style cutting tool for use in CNC machining centers accepting a 1 inch straight cylindrical shank; confirm toolholder bore and projection requirements before ordering.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the machine spindle fully stopped and the control in an e-stop or lockout state. Seat the shank fully in the toolholder to the recommended gauge-length mark before torquing the clamping mechanism per the toolholder manufacturer specifications. Verify runout with a dial test indicator after setup; excessive runout will accelerate edge wear and reduce surface finish quality. Follow applicable machine shop safety practices and the toolholder manufacturer torque guidelines.
