Sandvik Coromant 8036181 Corner Radius End Mill

Product Description

The SANDVIK COROMANT 8036181 is a solid carbide corner radius end mill designed for high-performance milling in demanding metalworking applications. It features a 1/4 inch diameter with a 0.01 inch corner radius, reducing stress concentration at the cutting edge and extending tool life. The four-flute, right-hand spiral design with variable helix and variable index geometry helps suppress vibration and chatter during aggressive cuts. An AlTiN coating provides thermal resistance and hardness at elevated cutting temperatures. This tool is single-end and center-cutting, suited for plunge, slot, and profile milling operations. It belongs to the CoroMill Dura series and carries the Material Grade designation X1BH.

This end mill is used in ferrous and hardened steel machining environments where surface finish and edge integrity are critical. It is well suited for die and mold work, general-purpose profile milling, and finish contouring passes. The 1 inch length of cut and 3 inch overall length make it appropriate for moderate-depth pocketing and side-wall finishing on CNC machining centers and manual mills with proper fixturing. Machinists, tool-and-die workers, and CNC operators working in job shops and production environments are the primary users.

Key Features

• 0.01 inch corner radius reduces edge chipping and improves workpiece surface finish
• AlTiN coating resists heat and wear during high-speed steel and alloy machining
• Variable helix and variable index geometry reduces harmonic vibration and chatter
• Four right-hand spiral flutes provide efficient chip evacuation
• Center-cutting design allows direct plunge entry into the workpiece
• Straight-cylindrical shank fits standard 1/4 inch collet chucks and end mill holders

Compatibility

Designed as an OEM-style solid carbide end mill for use in CNC machining centers and manual milling machines accepting a 1/4 inch straight-cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully in the collet or end mill holder and torque the retention mechanism to the machine or toolholder specification. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates wear on carbide tooling.
