Guhring 9069860127040 Corner Radius End Mill 5 Flute

Product Description

The GUHRING 9069860127040 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining environments. Built on Guhring Series 6986, it features a 1/2-inch mill diameter, a 0.03-inch corner radius, and five helical flutes with a medium-high helix angle of 38 degrees. The nano-A coating provides enhanced wear resistance and thermal stability, extending tool life across a wide range of workpiece materials. Suitable for both roughing and finishing operations, this single-end tool is engineered for rigorous cutting applications where tool geometry and coating consistency are critical to achieving close tolerances.

This end mill is intended for use in machining steel, stainless steel, cast iron, superalloys, titanium, non-ferrous metals, and hard materials. The Weldon flat shank provides positive engagement in end mill holders, making it appropriate for CNC machining centers and manual milling operations in tool-and-die, aerospace, and precision manufacturing settings. The non-centercutting, right-hand flute configuration is optimized for peripheral and slot milling passes where consistent chip evacuation and surface finish are priorities.

Key Features

• Solid carbide construction for rigidity and heat resistance in high-speed cutting
• nano-A coating for extended wear life across ferrous and non-ferrous materials
• 0.03-inch corner radius reduces stress concentration and extends edge life
• Five-flute design balances chip clearance with surface finish capability
• Weldon flat shank provides secure, positive clamping in end mill holders
• Suitable for both roughing and finishing material removal in a single tool

Compatibility

Designed for use with end mill holders on CNC machining centers and manual mills. Compatible with machining of steel, stainless steel, cast iron, superalloys, titanium, non-ferrous metals, and hard materials as listed in the Guhring Series 6986 application range.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the Weldon flat shank in a compatible end mill holder before mounting in the spindle, ensuring adequate clamping force per the holder manufacturer specifications. Verify spindle runout and holder condition prior to use to protect corner radius geometry and coating integrity. Do not use this tool as a plunge drill, as it is a non-centercutting configuration.
