Guhring 9030800079400 Corner Chamfer End Mill 4-flute

Product Description

The GUHRING 9030800079400 is a solid carbide corner chamfer end mill designed for precision milling applications in metal fabrication and machining operations. It features a 13/16 inch length of cut, a 2-1/2 inch overall length, and a 5/16 inch cylindrical shank. The tool carries a nano-A coating for improved wear resistance and tool life in demanding materials. With a 4-flute configuration and a variable helix angle of 36 to 38 degrees, it is engineered to reduce chatter and improve chip evacuation during finishing and chamfering passes. Licensed machinists and CNC operators install this tool in milling centers and machining cells.

This end mill is suited for single-end chamfering, corner breaking, and edge-prep work on ferrous and non-ferrous workpieces in production shop and job-shop environments. The right-hand cutting direction and right-hand flute direction make it compatible with standard milling machine spindle rotation. The variable helix geometry helps control vibration at higher feed rates, making it appropriate for both roughing chamfers and finish passes where surface quality matters. CNC machinists and tool-and-die professionals are the primary installers of this tool.

Key Features

• Solid carbide construction provides rigidity and heat resistance in high-speed cutting applications
• nano-A coating improves wear resistance and reduces friction at the cutting edge
• Variable helix angle of 36 to 38 degrees reduces harmonic vibration and chatter
• 4-flute, right-hand helical design supports efficient chip flow and surface finish quality
• Center-cutting capable, allowing plunge entry where required
• Cylindrical shank for direct clamping in collet chucks, end mill holders, or shrink-fit tooling

Compatibility

Designed as an OEM-style precision cutting tool for use in CNC machining centers and manual milling machines accepting a 5/16 inch cylindrical shank. Verify spindle taper, collet size, and tool holder clearance before installation.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before inserting or removing the tool from its holder. Seat the shank fully into the collet or tool holder and torque the retention hardware to the tool holder specification. Inspect the cutting edges and coating condition before each use and replace the tool at the first sign of chipping or excessive wear.
