Guhring 9042600047600 Square End Mill 3/16 in 4 Flute

Product Description

The GUHRING 9042600047600 is a solid carbide square end mill designed for precision milling in demanding ferrous applications. Part of the Series 4260, this single-end tool features a 3/16 inch cutting diameter, a 5/8 inch length of cut, and a 2.5 inch overall length. The variable helix geometry, with flute angles ranging from 36 to 38 degrees, reduces harmonic vibration and improves chip evacuation during interrupted or continuous cuts. The nano-A coating enhances wear resistance and surface lubricity, extending tool life in abrasive materials. With center-cutting capability and right-hand spiral flutes, this end mill handles both plunge entry and lateral milling in a single setup.

This end mill is engineered primarily for milling stainless steel and steel, with secondary suitability for cast iron. The extended reach design, with a 1.0 inch reach length and straight-cylindrical shank, suits applications requiring clearance in deeper pockets or stepped features. The 3/16 inch shank diameter matches the cutting diameter for straightforward toolholder selection. Typical applications include finish profiling, slotting, and contour milling in aerospace, medical, and general precision machining environments where tight tolerances and surface finish are critical.

Key Features

• Variable helix flute angles of 36 and 38 degrees reduce chatter and improve chip flow
• nano-A coating provides enhanced wear resistance for stainless steel and steel milling
• Center-cutting design allows direct plunge entry without pre-drilling
• Extended reach with 1.0 inch reach length for access to deeper features
• Solid carbide construction maintains rigidity at small diameters
• Right-hand cut and right-hand flute with spiral geometry for efficient chip removal

Compatibility

Designed as an OEM-style solid carbide square end mill for use with standard straight-bore toolholders accepting a 3/16 inch shank diameter, including collet chucks and end mill holders conforming to common machine tool interfaces.

Installation Notes

Installation and tool changes must be performed with the machine fully powered down and the spindle at a complete stop. A licensed or certified machinist should verify toolholder runout and shank seating before cutting. Ensure the shank is fully engaged in the collet or holder to the minimum insertion depth recommended by the toolholder manufacturer. Refer to GUHRING cutting data guidelines for appropriate feeds, speeds, and depth of cut for the target workpiece material.
