Guhring 9069900127000 Corner Radius End Mill Head 5 Flute

Product Description

The GUHRING 9069900127000 is a solid carbide corner radius end mill head from the Series 6990 line, designed for precision milling operations in metalworking and machining environments. This 5-flute tool features a 1.25-inch length of cut (LOC), a 3.5-inch overall length, and a 0.5-inch shank diameter with flats for secure toolholder engagement. The nano-A coating provides enhanced wear resistance and surface performance during cutting. With a variable index design and right-hand cutting direction, this end mill head is suited for high-precision finishing and profiling passes where controlled chip evacuation and edge integrity are critical.

This end mill head is intended for use in CNC machining centers and manual milling applications where a replaceable-head system is employed. The Series 6990 platform is used in ferrous and non-ferrous metalworking applications requiring consistent corner geometry. The helical flute configuration supports smooth chip flow in medium to high-speed cutting scenarios. Installation is performed by machinists and tool-and-die professionals in job shops, production machining facilities, and maintenance departments.

Key Features

• Solid carbide construction for rigidity and wear life in demanding cutting conditions
• nano-A coating for improved hardness and thermal resistance at the cutting edge
• 5 helical flutes with variable index for reduced chatter and improved surface finish
• Right-hand cutting direction with a 0.5-inch shank diameter and flat for positive drive
• Non-center-cutting design — intended for peripheral and side milling, not plunge cutting
• 1.25-inch LOC and 3.5-inch overall length suitable for moderate-depth profiling passes

Compatibility

Designed as a replacement-style end mill head for GUHRING Series 6990 compatible toolholding systems accepting a 0.5-inch shank with flats.

Installation Notes

Installation and changeout of end mill heads should be performed by qualified machinists following the toolholder manufacturer's torque and clamping procedures. Ensure the machine spindle is fully stopped and the machine is locked out before handling any cutting tool. Verify shank seating and flat alignment in the holder before initiating a cut. Non-center-cutting tools must not be used for direct plunge entry into solid material.
