Guhring 9069880127040 Corner Radius End Mill 5 Flute Carbide

Product Description

The GUHRING 9069880127040 is a solid carbide corner radius end mill designed for high-performance metal removal in demanding machining environments. It features a 1/2-inch mill diameter, a 0.03-inch corner radius, and five helical flutes ground to a medium-high helix angle for efficient chip evacuation. The nano-A coating provides enhanced wear resistance and thermal stability during extended cutting passes. With an extra-long 4-inch overall length and 1-5/8-inch length of cut, this tool suits deep-cavity and extended-reach milling applications. It is a single-end, right-hand cutting tool with a Weldon flat shank, rated for both roughing and finishing operations.

This end mill is engineered for use on steel, stainless steel, cast iron, superalloys, titanium, non-ferrous metals, and hard materials. It is well suited for production shops and tool rooms running CNC vertical or horizontal machining centers where consistent edge geometry and long tool life are critical. The Weldon flat shank is compatible with standard end mill holders, making it a direct fit for most production setups. The corner radius geometry reduces stress concentration at the cutting edge, extending tool life compared to sharp-corner end mills in interrupted or heavy cuts.

Key Features

• Solid carbide construction for rigidity and heat resistance in ferrous and hard-material applications
• nano-A coating for improved wear resistance and reduced built-up edge
• 0.03-inch corner radius with a tolerance of -0.002 to +0.002 inches for consistent edge geometry
• Extra-long 4-inch OAL with 1-5/8-inch LOC for deep-cavity and extended-reach milling
• Weldon flat shank for positive drive in standard end mill holders
• Five right-hand helical flutes with normal pitch for balanced roughing and finishing performance

Compatibility

Designed for use with standard end mill holders. Compatible with primary workpiece materials including steel, stainless steel, cast iron, superalloys, and titanium, as well as secondary materials including non-ferrous metals and hard materials.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the Weldon flat shank securely in the end mill holder and torque the set screw according to the holder manufacturer specifications. Verify runout with a dial indicator before beginning a production run to confirm proper seating and avoid premature edge wear.
