Guhring 9199560015900 Square End Mill 0.0625 in 4 Flute Carbide

Product Description

The GUHRING 9199560015900 is a solid carbide square end mill designed for precision material removal in demanding machining environments. Built to Series 19956 specifications, this single-end tool features a 0.0625-inch cutting diameter, a 0.1875-inch length of cut, and a 30-degree helical flute geometry that promotes efficient chip evacuation and reduces cutting forces. The FIREX coating adds heat resistance and surface hardness, extending tool life in abrasive and high-temp applications. With four right-hand helical flutes and a right-hand cut orientation, it delivers consistent finish quality in ferrous and stainless materials. This tool is suited for CNC milling operations run by machinists and tooling specialists working in tight-tolerance production environments.

This end mill is engineered for use on cast iron, stainless steel, and steel workpieces, corresponding to material codes K, M, and P. Secondary material compatibility covers material codes N and S. The 0.125-inch straight cylindrical shank fits standard collet chucks and ER-style toolholders used on vertical machining centers and CNC mills. Its 1.5-inch overall length and standard length-type classification make it a straightforward drop-in for typical small-diameter finish and semi-finish milling operations where reach is not a concern.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• FIREX coating provides elevated heat resistance and extended tool life
• 30-degree helix angle promotes smooth chip flow and reduces cutting pressure
• Four right-hand helical flutes for improved surface finish on finish passes
• Center-cutting capability allows direct plunge entry without a pre-drilled hole
• Mill diameter tolerance e8 and shank diameter tolerance h6 ensure precise fit in standard toolholders

Compatibility

Compatible with standard ER collet chucks and straight-bore toolholders accepting a 0.125-inch cylindrical shank. Intended for use on cast iron, stainless steel, and steel workpieces (material codes K, M, P); secondary compatibility with material codes N and S.

Installation Notes

Installation is performed by a machinist or tooling technician. Ensure the machine spindle is fully stopped and the control is in an e-stop or tool-change state before loading or unloading the cutter. Seat the shank fully into the collet or toolholder bore and torque the retention nut to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a production run, as runout on small-diameter carbide end mills accelerates tool wear and reduces surface finish quality.
