The UF(600) 2 flute micro end mill is designed for precision CNC machining where small tool diameters, cutting stability and reliable performance in difficult-to-machine materials are required.
Made from 0.6μm fine-grain carbide and coated with a high-performance AlCrN PVD coating, the tool provides excellent thermal stability, oxidation resistance and anti-adhesion performance. It is suitable for precision machining of stainless steel, titanium alloys and hardened steel up to 50 HRC.

The UF(600) is designed for micro and precision milling applications where tool size, cutting stability and material behavior are critical.
The AlCrN coating provides strong anti-adhesion performance to help reduce sticking and built-up edge when machining stainless steel.
Suitable for precision machining of titanium alloys and other difficult-to-machine materials where cutting heat and tool wear can become major concerns.
Suitable for hardened steel applications up to 50 HRC when appropriate cutting parameters and tool setup are used.
The micro end mill design is suitable for machining small features, narrow areas and precision components where conventional end mills may be too large.
The 2 flute micro configuration is designed for precision machining where small cutting diameters and controlled cutting conditions are required.
The fine-grain carbide substrate provides a combination of hardness, wear resistance and cutting stability for demanding micro machining applications.
The high-performance AlCrN coating provides strong resistance to high-temperature oxidation and supports stable cutting performance under elevated thermal loads.
When machining stainless steel, material adhesion and built-up edge can affect tool life and surface quality. The UF(600) coating is designed to help reduce these problems.

The available diameter, flute length, shank diameter and overall length should be selected according to the machining feature and required tool reach.
Choosing a micro end mill requires more than selecting the smallest available diameter.
Select the UF(600) when machining stainless steel, titanium alloys, hardened steel or other difficult-to-machine materials.
Select the smallest practical tool diameter that provides adequate rigidity for the feature being machined.
Longer tool overhang can increase deflection and vibration, especially with micro-diameter tools. Use the shortest practical tool configuration for the application.
Micro tools require carefully controlled spindle speed, feed rate, depth of cut and tool overhang.
Micro end mills are sensitive to tool overhang, machine rigidity, spindle accuracy and cutting conditions.
Recommended parameters should be selected according to:
