Guhring 9031900190500 Square End Mill 0.75in 4 Flute Carbide

Product Description

The GUHRING 9031900190500 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. This single-end tool features a 0.75-inch cutting diameter, a 1.5-inch length of cut, and a 5-inch overall length. The 4-flute, right-hand spiral geometry with a 20-degree helix angle promotes efficient chip evacuation and smooth cutting action. A FIREX coating provides enhanced heat resistance and extended tool life in demanding cutting environments. The straight cylindrical shank measures 0.75 inches in diameter with an h6 tolerance for secure toolholder engagement. Machinists and CNC operators in job shops, aerospace, and general metalworking applications rely on this series for consistent performance.

The 9031900190500 belongs to GUHRING Series 3190, a long-series end mill line suited for applications requiring extended reach without sacrificing rigidity. With a reach length of 3.0 inches and a mill diameter tolerance of h11, this tool is appropriate for finishing and semi-finishing passes in pockets, slots, and profiling operations on machining centers and CNC mills. The centercutting design allows for direct plunge entry. It is intended for single-end use and is not designed for double-end reversal.

Key Features

• Solid carbide construction for rigidity and wear resistance at elevated cutting speeds
• FIREX coating for improved thermal resistance and reduced friction in hard material applications
• 4-flute, right-hand spiral flute design with 20-degree helix for balanced chip load and surface finish
• Centercutting geometry permits direct plunge milling
• Straight cylindrical shank with h6 tolerance ensures precise, repeatable toolholder fit
• Long-series configuration with 3.0-inch reach length for accessing deeper features

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for standard 0.75-inch bore toolholders including collet chucks, end mill holders, and shrink-fit holders accepting a straight cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool release is engaged before installing or removing the end mill. Clean the toolholder bore and shank thoroughly before assembly to achieve proper runout within the h6 shank tolerance. Follow the toolholder manufacturer torque specifications for set screws or collet nuts — do not overtighten collet nuts, as this can deform the shank or affect runout.
