Sandvik Coromant 8036800 Corner Radius End Mill 3/8in 5 Flute

Product Description

The SANDVIK COROMANT 8036800 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. Measuring 3/8 inches in diameter with a 0.06 inch corner radius, this single-end, centercutting tool features 5 flutes with a variable helix and variable index geometry. The AlTiN coating improves heat resistance and extends tool life in high-speed cutting conditions. With a 1-1/2 inch length of cut and 3-1/2 inch overall length, it is suited for finishing and semi-finishing passes in ferrous and hardened materials. Part of the CoroMill Dura series, it is installed by machinists and CNC operators in production and job-shop environments.

This end mill is used in vertical and horizontal machining centers where corner radius geometry is required to reduce stress concentrations and improve surface finish on part features. The right-hand flute direction and right-hand cutting geometry make it compatible with standard CNC spindle configurations. The straight-cylindrical shank seats directly in standard collet chucks and end mill holders with a 3/8 inch bore. Typical applications include profiling, slotting, and contouring operations on steel, stainless steel, and high-temperature alloys where the AlTiN coating provides thermal protection at elevated feed rates and cutting speeds.

Key Features

• Solid carbide construction for rigidity and dimensional stability under cutting loads
• AlTiN coating for heat resistance and extended tool life in ferrous and hardened materials
• Variable helix and variable index design reduces chatter and vibration during milling
• Centercutting geometry allows plunge entry without a pre-drilled pilot hole
• 5-flute configuration supports higher feed rates compared to standard 4-flute end mills
• Corner radius profile reduces edge chipping and improves surface finish at part corners

Compatibility

Designed as an OEM-style solid carbide end mill for use in standard 3/8 inch collet chucks, shrink-fit holders, and end mill holders on CNC vertical and horizontal machining centers. Part of the SANDVIK COROMANT CoroMill Dura series, material grade X1BH.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the straight-cylindrical shank fully into the holder bore and torque the retention screw or collet nut to the holder manufacturer's specification. Verify runout with a dial indicator before commencing a production cut.
