Guhring 9035400140000 Square End Mill 0.551 in 3 Flute

Product Description

The GUHRING 9035400140000 is a solid carbide square end mill designed for high-performance material removal in ferrous machining environments. Built on Guhring Series 3540, this stub-length tool features a 0.551-inch cutting diameter, three spiral flutes with a 45-degree helix angle, and a FIREX finish applied over the carbide substrate for extended tool life. The single-end, center-cutting design supports plunge entry as well as peripheral and slot milling operations. It is intended for use by machinists and tool-and-die professionals working on CNC or manual milling machines where dimensional accuracy and surface finish are critical.

This end mill is suited for machining cast iron, stainless steel, and steel alloys, covering primary workpiece material codes K, M, and P, with secondary suitability for non-ferrous and superalloy materials (codes N and S). The stub-length configuration offers maximum rigidity with minimal overhang, making it well-suited for short-reach pocketing, facing, and shoulder milling applications in production and job-shop environments. The straight cylindrical shank seats directly into standard collets or end mill holders without adapters.

Key Features

• FIREX coating for improved heat resistance and extended tool life on ferrous materials
• 45-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Center-cutting geometry allows direct plunge entry without pre-drilling
• Stub-length body maximizes rigidity and reduces deflection in short-reach cuts
• Right-hand cut and right-hand flute configuration for standard spindle operation
• No chipbreaker — optimized for smooth finish passes and consistent chip load

Compatibility

Designed as an OEM-specification solid carbide square end mill for use in standard straight-shank end mill holders and collet chucks accepting a 0.5512-inch (14.00 mm) shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tooling setup. Power down and lock out the spindle before inserting or removing the tool from the holder. Ensure the shank is clean and fully seated to the recommended engagement depth in the collet or end mill holder before clamping. Do not exceed the tool manufacturer recommended cutting parameters for the target workpiece material to avoid premature wear or tool failure.
