UF(600) 2 flute micro long neck carbide square end mill with 0.6μm fine-grain carbide and AlCrN PVD coating, designed for precision deep-groove and cavity machining of stainless steel, titanium alloys and hardened steel up to 50 HRC.
The UF(600) 2 flute micro long neck end mill is designed for precision CNC machining of small, deep and difficult-to-reach features.
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. Its micro-diameter long neck configuration is suited to deep grooves, narrow pockets and recessed cavities in stainless steel, titanium alloys and hardened steel up to 50 HRC.
Key Features
Recommended Applications
The UF(600) is designed for micro and precision machining where both small tool diameter and extended reach are required.
Deep Micro Groove Milling
Suitable for narrow and deep grooves where a standard micro end mill cannot provide sufficient reach.
Deep Cavity Machining
The long neck design provides additional clearance for recessed cavities and deep features.
Narrow Feature Machining
Suitable for small openings, narrow pockets and restricted areas where tool access is limited.
Precision Mold Machining
Designed for small cavities, inserts, cores and other precision mold features requiring extended tool reach.
Difficult-to-Machine Materials
Suitable for stainless steel, titanium alloys and hardened steel up to 50 HRC under appropriate cutting conditions.
Why Choose the UF(600) Micro Long Neck End Mill?
Micro Diameter for Small Features
The micro end mill configuration is designed for machining small features and restricted areas where conventional tools are too large.
Long Neck for Deep Reach
The extended neck provides additional clearance behind the cutting section, allowing the tool to reach deeper features while reducing interference with surrounding workpiece areas.
0.6μm Fine-Grain Carbide
The fine-grain carbide substrate provides a balance of hardness, wear resistance and cutting stability for demanding micro milling applications.
AlCrN PVD Coating
The AlCrN coating provides strong resistance to high-temperature oxidation and supports stable performance under demanding thermal conditions.
Strong Anti-Adhesion Performance
When machining stainless steel, material adhesion and built-up edge can negatively affect tool life and surface finish. The AlCrN coating helps reduce these common problems.
Designed to Solve Common Micro Long Neck Milling Problems
| Common Problem | UF(600) Solution |
| Standard tool cannot reach a deep feature | Long neck design provides additional machining reach |
| Micro features require a small cutting diameter | Micro-diameter configuration supports precision machining |
| Tool interference in narrow cavities | Reduced neck section provides additional clearance |
| Stainless steel causes built-up edge | AlCrN coating helps reduce material adhesion |
| Small tools wear quickly | Fine-grain carbide supports wear resistance |
| Long tool extension causes instability | Use the shortest practical overhang and appropriate cutting parameters |
Micro long neck tools are more sensitive to tool deflection and vibration than standard-length tools. Keeping the unsupported tool length as short as practical is important for stable machining.
Material Compatibility
| Workpiece Material | Recommended Application |
| Stainless Steel | Precision micro milling and deep-feature machining |
| Titanium Alloy | Difficult-to-machine micro applications |
| Hardened Steel ≤50 HRC | Suitable with appropriate cutting conditions |
| Other Difficult-to-Machine Materials | Application dependent |
Actual performance depends on workpiece grade, hardness, tool diameter, effective length, tool overhang, machine rigidity, cutting parameters and cooling conditions.

Dimensional Information
For micro long neck tools, the following dimensions should be evaluated together:
How to Select the Right Micro Long Neck End Mill
Choosing a micro long neck end mill requires balancing reach, rigidity and cutting performance.
Determine the minimum groove, pocket or cavity width that needs to be machined.
Choose the smallest practical diameter that provides sufficient cutting strength for the application.
Select an effective length that reaches the deepest machining feature without unnecessary tool extension.
The neck should provide enough clearance from surrounding workpiece surfaces while maintaining adequate tool strength.
Micro long neck tools are sensitive to deflection and vibration. Use the shortest practical setup for improved stability.
For stainless steel, titanium alloys and hardened steel, select cutting conditions based on the material grade, hardness and tool diameter.
Recommended Cutting Conditions
