Sandvik Coromant 8036856 Corner Radius End Mill 5/8in 5 Flute

Product Description

The SANDVIK COROMANT 8036856 is a solid carbide corner radius end mill designed for demanding milling operations where edge strength and surface finish are critical. Part of the CoroMill Dura series, it features a 5/8-inch diameter with a 0.06-inch corner radius and five flutes ground to right-hand cutting and flute direction. The AlTiN coating provides high heat resistance and extended tool life in ferrous and hardened materials. With a variable helix and variable index geometry, it reduces chatter and improves chip evacuation. Licensed machinists and CNC operators in job shops and production environments rely on this geometry for aggressive material removal with controlled deflection.

This end mill is suited for side milling, slotting, and profiling in steel, stainless steel, and hardened alloy materials. The 2-1/4-inch length of cut and 5-inch overall length support deep-reach applications without requiring extension tooling in many setups. The straight cylindrical shank accepts standard ER and side-lock toolholders. Centercutting capability allows direct plunge entry. It is a single-end tool intended for use in vertical machining centers and CNC milling machines across aerospace, die-mold, and general metalworking applications.

Key Features

• Solid carbide construction in Material Grade X1BH for rigidity and wear resistance
• AlTiN coating for high-temperature performance in ferrous and hardened materials
• Variable helix and variable index geometry to suppress vibration and chatter
• 0.06-inch corner radius reduces stress concentration and improves corner durability
• Five-flute design balances chip clearance with surface finish quality
• Centercutting, single-end configuration supports plunge and ramp entry

Compatibility

Designed as a direct-fit replacement-style solid carbide end mill for standard 5/8-inch straight cylindrical toolholders including ER collet chucks and side-lock holders used in vertical machining centers and CNC mills.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Verify holder runout and tool projection before initiating a cut. Do not exceed the recommended depth of cut or feed rate for the workpiece material and machine rigidity.
