Guhring 9069910127000 Corner Radius End Mill Head

Product Description

The GUHRING 9069910127000 is a solid carbide corner radius end mill head designed for high-performance milling operations. Part of the Series 6991 lineup, it features 5 helical flutes and a nano-A coating that extends tool life in demanding cutting conditions. The 2-inch length of cut and 4.25-inch overall length make it well suited for deep-pocket and profile milling where reach and rigidity are both required. Right-hand cutting direction and a variable index design help reduce chatter and improve surface finish on ferrous and non-ferrous materials. Licensed machinists and toolroom professionals are the primary users of this replaceable head system.

This end mill head is built for precision machining applications including mold work, die machining, and general CNC milling where tight tolerances and consistent edge geometry are critical. The replaceable head format reduces tooling cost by allowing the carbide cutting head to be swapped without replacing the full shank assembly. It is not center-cutting, so it is intended for peripheral and side milling rather than direct plunge operations. The nano-A coating provides oxidation resistance and reduced friction at elevated cutting temperatures.

Key Features

• Solid carbide construction for rigidity and wear resistance
• nano-A coating for extended tool life and reduced cutting friction
• 5 helical flutes with variable index geometry to suppress vibration
• 2-inch length of cut suitable for deep-pocket milling passes
• Right-hand cutting direction for standard CNC spindle compatibility
• Replaceable head design reduces cost-per-edge compared to solid shank tools

Compatibility

Designed as a Series 6991 replacement end mill head for compatible GUHRING modular shank systems accepting this head diameter and interface type.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician following the machine tool builder and toolholder manufacturer torque guidelines. Ensure the machine spindle is fully stopped and locked out before changing any cutting head. Verify the mating shank interface is clean and free of chips or debris before seating the head to ensure proper seating and runout. Confirm that the selected depth of cut and feed rate are appropriate for this non-center-cutting geometry before programming plunge moves.
