Guhring 9031530023800 Square End Mill 3/32 in 4 Flute

Product Description

The GUHRING 9031530023800 is a solid carbide square end mill from the Series 3153 line, designed for precise material removal in ferrous and high-alloy machining applications. With a 3/32 inch (0.0938 inch) cutting diameter and a 9/32 inch (0.2813 inch) length of cut, this tool is built for tight-tolerance slotting, profiling, and contouring work. The four-flute geometry with a 30-degree helix angle supports efficient chip evacuation while maintaining surface finish quality. A FIREX coating provides heat and wear resistance, extending tool life in demanding cuts. CNC machinists and tool-and-die professionals reach for this size class when working in confined features or thin-wall part geometries.

This end mill is suited for machining cast iron, stainless steel, and steel workpieces in precision milling operations. The 1/8 inch straight cylindrical shank fits standard ER collet chucks and end mill holders common to vertical machining centers and CNC mills. At 1-1/2 inch overall length, the tool maintains rigidity in short-reach applications. The centercutting design allows plunge entry, expanding its usefulness in pocketing and ramping operations where a separate drilling step is not practical.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• FIREX coating for elevated heat resistance and extended tool life
• Four-flute spiral geometry with 30-degree helix angle for balanced chip load and surface finish
• Centercutting capability supports direct plunge and ramp entry
• Right-hand cut, right-hand flute configuration for standard spindle operation
• Mill diameter tolerance h10 and shank diameter tolerance h6 for consistent fit and runout control

Compatibility

Designed for use in standard 1/8 inch collet chucks and end mill holders on CNC vertical machining centers and manual mills. Rated for primary workpiece materials including cast iron (K), stainless steel (M), and steel (P), with secondary suitability for non-ferrous and superalloy materials (N, S).

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Verify collet size matches the 1/8 inch shank diameter and torque the tool holder per the equipment manufacturer's specifications. Do not exceed the tool's rated cutting diameter or length-of-cut depth in a single pass without confirming feeds and speeds for the specific workpiece material.
