Sandvik Coromant 8036189 Corner Radius End Mill 1/4 in

Product Description

The SANDVIK COROMANT 8036189 is a solid carbide corner radius end mill from the CoroMill Dura series, designed for high-performance milling in demanding machining applications. With a 1/4 inch mill diameter, a 0.06 inch corner radius, and an AlTiN coating, this tool delivers heat and wear resistance suited for hard and abrasive materials. The 4-flute configuration and 1-1/4 inch length of cut support efficient material removal in ferrous and high-temperature alloys. It is intended for use by machinists and tooling professionals working on CNC milling centers and machining cells where tool life and surface finish are critical.

This end mill is well suited for slotting, profiling, and contouring operations in both roughing and finishing passes. The CoroMill Dura series targets applications requiring consistent tool life across medium to high hardness workpiece materials. The variable helix and variable index geometry reduce chatter and vibration during interrupted cuts or longer reaches. At 3 inches overall length with a straight-cylindrical 1/4 inch shank, it fits standard ER and straight-shank toolholders commonly used in vertical and horizontal machining centers. Right-hand cutting direction and centercutting capability allow plunge entry as well as conventional peripheral milling.

Key Features

• AlTiN coating provides elevated heat resistance and extended tool life in hard and abrasive materials
• Variable helix and variable index geometry reduce harmonic vibration and chatter
• Centercutting design enables direct plunge entry without a pre-drilled hole
• 4-flute spiral configuration balances chip evacuation with surface finish quality
• Solid carbide construction supports higher feed rates and greater rigidity than HSS alternatives
• Material grade X1BH optimized for the CoroMill Dura series application range

Compatibility

Designed as an OEM-style replacement and standard offering within the SANDVIK COROMANT CoroMill Dura series. Fits standard straight-cylindrical 1/4 inch shank toolholders including ER collet chucks compatible with that shank diameter.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the spindle fully stopped and machine in a locked-out state per applicable safety procedures. Ensure the toolholder bore and collet are clean and free of debris before seating the shank. Torque the toolholder to the toolholder manufacturer specifications — do not use values not provided in this listing. Confirm runout with a dial indicator before initiating a cut to protect both the tool and the workpiece.
