Guhring 9031480019800 Square End Mill 0.0781 in 2 Flute Carbide

Product Description

The GUHRING 9031480019800 is a solid carbide square end mill designed for precision milling in demanding machining applications. Part of the Guhring Series 3148, it features a 0.0781 inch (5/64 inch) cutting diameter, a 0.25 inch length of cut, and a 1.5 inch overall length. The tool carries a FIREX multi-layer coating that increases surface hardness and heat resistance, extending tool life in abrasive and elevated-temperature cutting conditions. With a 30-degree helix angle and two right-hand spiral flutes, it provides efficient chip evacuation and consistent cutting performance on a range of workpiece materials. Licensed machinists and CNC operators rely on this end mill for tight-tolerance profiling, slotting, and contouring work.

This end mill is suited for milling operations in CNC machining centers and manual knee mills where a small-diameter, short-reach tool is required. The straight cylindrical shank diameter of 0.125 inch (1/8 inch) fits standard ER collets and precision tool holders commonly found in production and job-shop environments. Primary workpiece material codes K, M, N, and P indicate suitability for cast iron, stainless steel, non-ferrous metals, and steel. Secondary material code S indicates it can also be applied to heat-resistant superalloys with appropriate parameters. The centercutting geometry allows plunge entry as well as conventional peripheral milling.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision milling
• FIREX multi-layer coating enhances heat resistance and extends tool life
• 30-degree helix angle with right-hand spiral flutes for efficient chip evacuation
• Centercutting design supports direct plunge entry
• Straight cylindrical shank (0.125 inch, h6 tolerance) for secure collet clamping
• Mill diameter held to h10 tolerance for consistent fit and repeatability

Compatibility

Suitable for use in CNC machining centers and manual mills with standard ER or precision collet toolholders accepting a 0.125 inch straight shank. Compatible with workpiece material codes K, M, N, P, and S as specified by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the collet or tool holder. Use a calibrated torque wrench on the collet nut to secure the shank without over-tightening, which can cause shank damage or runout. Verify runout with a dial indicator before beginning a production cut, particularly given the small diameter of this tool.
