Guhring 9031530087300 Square End Mill 0.3438 in 4 Flute

Product Description

The GUHRING 9031530087300 is a solid carbide square end mill designed for high-performance material removal in demanding machining applications. Built to Series 3153 specifications, it features a 0.3438-inch cutting diameter, a 1-inch length of cut, and a 4-flute spiral geometry with a 30-degree helix angle. The FIREX coating provides thermal and wear resistance suited for dry or semi-dry cutting conditions. This is a single-end, right-hand cut tool with a straight-cylindrical shank measuring 0.375 inches in diameter and an overall length of 2.5 inches. Machinists and tool-and-die professionals specify this end mill for precision slotting, profiling, and peripheral milling where tight tolerances and surface finish are priorities.

This end mill is center-cutting and rated for use in cast iron, stainless steel, and steel as primary workpiece materials, with secondary suitability for non-ferrous and superalloy applications. Its regular length type and compact 2.5-inch overall length make it well suited for CNC machining centers and manual mills where rigidity and minimal tool overhang are required. The h10 mill diameter tolerance and h6 shank diameter tolerance support consistent fitment in standard collets and tool holders used in production and job-shop environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and stainless materials
• FIREX coating for elevated thermal protection and extended tool life in dry cutting
• 4-flute spiral design with 30-degree helix angle for efficient chip evacuation and smooth surface finish
• Center-cutting geometry allows direct plunge entry into workpiece material
• Straight-cylindrical shank at 0.375 inches diameter with h6 tolerance for precise collet retention
• Right-hand flute and right-hand cut configuration compatible with standard CNC spindle rotation

Compatibility

Designed as an OEM-style solid carbide square end mill compatible with standard straight-bore collet systems and tool holders accepting a 0.375-inch straight-cylindrical shank. Primary workpiece materials include cast iron, stainless steel, and steel; secondary compatibility covers non-ferrous and superalloy materials per Series 3153 design intent.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in a safe lockout state before changing tooling. Seat the shank fully in the collet or tool holder and torque the retention mechanism to the tool holder specification. Verify runout with a dial indicator before engaging the workpiece, particularly in tight-tolerance finishing operations.
