Guhring 9031550095200 Square End Mill 0.375in 4 Flute Carbide

Product Description

The GUHRING 9031550095200 is a solid carbide square end mill designed for precision metal removal in demanding machining environments. Built to Series 3155 standards, it features a 0.375-inch cutting diameter, a 1.625-inch length of cut, and a 4-inch overall length, making it an extra-long reach tool suited for deeper pocketing and slotting operations. The FIREX coating provides enhanced heat and wear resistance, extending tool life in abrasive and high-temperature cutting conditions. Four right-hand spiral flutes with a 30-degree helix angle promote efficient chip evacuation and smooth cutting action. This end mill is installed and operated by machinists and CNC tooling professionals.

This end mill is well-suited for milling cast iron, stainless steel, and steel workpieces, covering primary material grades K, M, and P. Its extra-long length of cut makes it effective in applications requiring reach beyond standard end mill proportions, including deep slots, pockets, and stepped features. The straight cylindrical shank with a 0.375-inch shank diameter allows direct mounting in standard collet chucks and end mill holders. Secondary material compatibility extends to non-ferrous and superalloy grades N and S, broadening its application range.

Key Features

• FIREX coating for elevated heat resistance and extended tool life in ferrous materials
• 30-degree helix angle with right-hand spiral flutes for efficient chip flow
• Extra-long 1.625-inch length of cut for deep pocket and slot work
• Center-cutting design allows plunge entry without a pre-drilled hole
• Solid carbide construction for rigidity and dimensional stability
• Mill diameter tolerance h10 and shank diameter tolerance h6 for consistent fit and runout control

Compatibility

Designed for use in CNC machining centers and manual mills with standard collet or end mill holder systems accepting a 0.375-inch straight cylindrical shank. Primary workpiece materials include cast iron, stainless steel, and steel; secondary compatibility includes non-ferrous and superalloy materials.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the collet or tool holder and torque the retention hardware to the machine manufacturer's specifications. Verify runout with a dial indicator before beginning a cut, and confirm that spindle speed and feed rate are set appropriately for the workpiece material and depth of cut.
