Guhring 9067370137000 Square End Mill 0.5394in 4 Flute

Product Description

The GUHRING 9067370137000 is a solid carbide square end mill designed for high-performance metal removal in CNC machining and manual milling operations. Belonging to the RF100 series, this single-end tool features a 0.5394-inch mill diameter with a 1.0236-inch length of cut and a 0.5512-inch straight cylindrical shank. The variable helix geometry reduces harmonic chatter during aggressive cuts, while the nano-Si coating improves heat resistance and tool life. With four right-hand helical flutes and center-cutting capability, this end mill handles both plunge and peripheral milling. Machinists and toolroom professionals working in production or job-shop environments install this class of tooling.

This end mill is engineered for a broad range of workpiece materials. The primary workpiece material codes listed are K (cast iron), M (stainless steel), P (steel), and S (high-temperature alloys and titanium). Secondary compatibility extends to N-group materials (non-ferrous metals). The RF100 series is suited for roughing and finishing passes in general-purpose and aerospace-grade materials. The h6 shank tolerance ensures a precise fit in standard collet chucks and end mill holders, making it appropriate for high-RPM applications on modern machining centers.

Key Features

• Solid carbide construction for rigidity and long tool life in demanding materials
• Variable helix design reduces vibration and chatter during cutting
• nano-Si coating enhances wear resistance and heat dissipation
• Center-cutting geometry allows direct plunge entry into workpiece
• h6 shank tolerance provides consistent, accurate seating in collet and end mill holders
• Right-hand cut, right-hand flute configuration for standard spindle compatibility

Compatibility

Designed for use with K, M, P, and S primary workpiece material groups, with secondary compatibility for N-group materials, as defined in the supplier specifications for the GUHRING RF100 series.

Installation Notes

Installation of this end mill is performed by a qualified machinist or CNC toolsetter. Power down and lock out the machine spindle before changing tooling. Seat the shank fully into a properly sized collet or end mill holder and torque the retention hardware to the machine manufacturer's specification. Verify runout with a dial indicator before beginning a cutting program, and confirm spindle speed and feed rate settings are appropriate for the workpiece material and depth of cut.
