Guhring 9069970127000 Corner Radius End Mill Head 7 Flute

Product Description

The GUHRING 9069970127000 is a corner radius end mill head designed for precision milling operations in metalworking and machining environments. Built from solid carbide and finished with a nano-A coating, this tool delivers hardness and wear resistance suited for demanding cutting applications. It features 7 helical flutes, a right-hand cutting direction, and a variable index geometry that helps reduce harmonic vibration during high-feed passes. The overall length is 3.5 inches with a length of cut of 1.25 inches. The 1/2-inch shank diameter includes flats for secure tool holding. This end mill head is part of the GUHRING Series 6997 and is installed by machinists and CNC tooling professionals.

This tool is suited for precision contouring, profiling, and finishing passes in ferrous and non-ferrous materials. It is a non-centercutting design, meaning it is intended for side milling and profiling rather than plunge cuts. The 7-flute configuration increases the number of cutting edges per revolution, making it effective for high-speed finishing applications where surface finish quality and tool life are priorities. The shank with flats accommodates set-screw style tool holders commonly used in modular and gang tooling setups on CNC machining centers.

Key Features

• Solid carbide construction for rigidity and thermal stability at high cutting speeds
• nano-A coating provides enhanced wear resistance on the cutting edges
• 7 helical flutes for improved chip evacuation and surface finish quality
• Variable index flute spacing reduces chatter and harmonic vibration
• Right-hand cutting direction with 1/2-inch shank diameter with flats for secure clamping
• Non-centercutting geometry optimized for profiling and peripheral milling operations

Compatibility

Designed as a replacement-style end mill head within the GUHRING Series 6997 modular tooling system. Compatible with tool holders accepting a 1/2-inch shank diameter with flats.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and all energy sources are locked out before changing tooling. Verify that the tool holder bore and set-screw torque specifications match the tool holder manufacturer requirements. Confirm the tool is seated to the correct gauge length before initiating any cutting program.
