Sandvik Coromant 8037412 Corner Radius End Mill

Product Description

The SANDVIK COROMANT 8037412 is a solid carbide corner radius end mill designed for high-performance milling operations in demanding machining environments. With a 0.5 inch diameter and a 0.1250 inch corner radius, this three-flute tool delivers controlled material removal while reducing stress concentrations at part corners. The variable helix and variable index design help minimize chatter and vibration during cutting. Built from H10F carbide grade with a bright/uncoated finish, it is suited for machinists and tooling technicians running CNC milling operations where dimensional accuracy and tool life are critical priorities.

This end mill belongs to the CoroMill Dura series and is configured as a single-end, centercutting tool with a 2 inch length of cut and a 4 inch overall length. It accepts a 1/2 inch straight-cylindrical shank, making it compatible with standard collet chucks and end mill holders. The 35-degree helix angle and right-hand cutting direction suit typical roughing and semi-finishing passes in steel, stainless, and similar materials where a carbide grade like H10F performs reliably.

Key Features

• Solid carbide H10F grade construction for hardness and wear resistance
• 0.1250 inch corner radius reduces stress risers on machined part features
• Variable helix and variable index geometry minimizes vibration and chatter
• Centercutting capability allows plunge entry into workpieces
• Bright/uncoated finish suitable for applications where coating is not required
• Right-hand flute direction with 35-degree helix for efficient chip evacuation

Compatibility

Designed as an OEM-style replacement and standard tooling option within the CoroMill Dura series, compatible with standard 1/2 inch end mill holders, collet chucks, and shrink-fit tooling systems accepting a straight-cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with CNC milling setup procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify that the holder bore is clean and free of chips before seating the shank, and confirm runout with a dial indicator after tightening to manufacturer torque specifications for the holder type in use. Do not exceed the tool's rated depth of cut or feed rates for the workpiece material.
