Guhring 9030960158700 Square End Mill 0.625 in 4 Flute

Product Description

The GUHRING 9030960158700 is a solid carbide square end mill designed for high-performance material removal in ferrous and hard-to-machine applications. Part of the Series 3096, it features a 0.625-inch cutting diameter, 1-inch length of cut, and a 40-degree helix angle that improves chip evacuation and reduces cutting forces. The FIREX coating provides enhanced heat and wear resistance, extending tool life in demanding cuts. Center-cutting geometry allows for plunge entry, and the variable index design reduces harmonic vibration during milling. This tool is installed and operated by machinist-level trade professionals in job shop and production environments.

This end mill is suited for milling cast iron, steel, stainless steel, and hard materials in single-end configurations. It is well matched to CNC vertical and horizontal machining centers where rigid setups and controlled feeds and speeds can be maintained. The Weldon flat shank provides positive drive retention in side-lock toolholders, making it appropriate for aggressive slotting, profiling, and peripheral milling operations on ferrous workpieces.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and hard-material cuts
• FIREX coating improves heat resistance and tool life over uncoated carbide
• 40-degree helix angle promotes efficient chip flow and reduced cutting pressure
• Variable index flute spacing dampens vibration during interrupted or aggressive cuts
• Center-cutting capable — supports direct plunge entry without pre-drilling
• Weldon flat shank for secure seating in side-lock and Weldon-style toolholders

Compatibility

Designed for use with 5/8-inch side-lock or Weldon-style toolholders on CNC machining centers. Primary workpiece materials are cast iron and steel; secondary materials include stainless steel and hard materials per ISO material codes P, K, H, M, and S. Series 3096 from GUHRING.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholder torque and runout specifications. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the Weldon flat shank fully into the holder and engage the set screw against the flat to prevent axial pull-out during cutting. Verify runout at the cutting edge before initiating a cut, as excessive runout accelerates edge wear and reduces surface finish quality.
