Guhring 9031560111100 Square End Mill 0.4375 in 4 Flute

Product Description

The GUHRING 9031560111100 is a solid carbide square end mill designed for precision milling operations in metal fabrication, tool and die, and general machining environments. Part of the Series 3156 long-reach line, it features a 0.4375 inch cutting diameter, 2 inch length of cut, and a 4.5 inch overall length. The four spiral flutes are ground with a 30-degree helix angle for efficient chip evacuation and smooth cutting action. A FIREX coating is applied to the flute and cutting geometry to extend tool life in ferrous and hardened materials. This end mill is installed and operated by machinists and toolroom technicians using CNC machining centers or manual vertical mills.

This tool is suited for long-reach slotting, profiling, and peripheral milling applications where standard-length end mills cannot reach the workpiece. The 0.4375 inch shank diameter matches the cutting diameter for direct chuck or collet mounting. The right-hand spiral flute and right-hand cutting direction make it compatible with conventional CNC spindle configurations. It is classified as a long-length end mill, appropriate for deep-cavity work in mold making, aerospace component machining, and similar precision applications.

Key Features

• 0.4375 inch cutting diameter with matching 0.4375 inch shank for direct collet mounting
• 2 inch length of cut supports deep-cavity and long-reach milling
• Four spiral flutes at 30-degree helix angle for efficient chip removal
• FIREX coating extends cutting life in ferrous and hardened workpiece materials
• Right-hand flute direction and right-hand cut for standard CNC spindle use
• Single-end, non-centercutting geometry — not suitable for direct plunge entry

Compatibility

Designed for use in standard 7/16 inch collets or end mill holders on CNC machining centers and manual vertical mills; part of the GUHRING Series 3156 long-length solid carbide end mill line.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank fully into a matched collet or end mill holder and torque the retention system per the machine tool manufacturer specification before operation. This tool is non-centercutting and must not be used for direct axial plunge cuts without a pre-drilled or ramped entry path. Inspect the cutting edge and coating condition before each use; discard if chipping or coating delamination is observed.
