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 combines wear resistance, thermal stability and strong anti-adhesion performance. Its 2-flute micro long neck configuration is suitable for deep grooves, narrow pockets and recessed cavities in stainless steel, titanium alloys and hardened steel up to 50 HRC.
Key Features
Recommended Applications
Deep Micro-Groove Milling
The micro-diameter cutting geometry is suitable for narrow grooves and small features where both precision and extended reach are required.
Deep Cavity Machining
The long neck provides additional clearance for recessed cavities and deep features that are difficult to access with standard-length tools.
Narrow Pocket Machining
Designed for restricted machining areas where a conventional tool body may interfere with surrounding workpiece surfaces.
Precision Mold Components
Suitable for small mold cavities, inserts, cores and other precision features requiring a combination of small diameter and extended 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 Diameter for Precision Features
The micro end mill configuration is designed for small features and restricted areas where a conventional end mill may be too large.
Long Neck for Extended Clearance
The reduced-neck configuration provides additional clearance behind the cutting section, helping the tool reach deep or recessed features while limiting interference.
2-Flute Cutting Geometry
The 2-flute design provides open flute space for chip evacuation and is well suited to small-diameter milling applications where cutting conditions need to be carefully controlled.
Fine-Grain Carbide Substrate
The 0.6μm fine-grain carbide provides a balance of hardness, wear resistance and cutting stability for demanding precision machining.
AlCrN PVD Coating
The AlCrN coating provides high-temperature oxidation resistance and supports cutting performance under elevated thermal loads.
Strong Anti-Adhesion Performance
When machining stainless steel, adhesion and built-up edge can affect tool life and surface quality. The AlCrN coating helps reduce these common machining problems.
Solve Common Micro Long Neck Milling Challenges
| Machining Challenge | UF(600) Solution |
| Standard tool cannot reach the feature | Long neck design provides additional clearance |
| Small groove or cavity is difficult to access | Micro-diameter configuration fits restricted features |
| Toolholder interference | Reduced neck provides clearance behind the cutting section |
| Stainless steel causes built-up edge | AlCrN coating helps reduce material adhesion |
| Micro tools wear quickly | Fine-grain carbide supports wear resistance |
| Long tool setup becomes unstable | Shortest practical overhang should be used to improve rigidity |
Micro long neck tools are inherently more sensitive to deflection and vibration than shorter tools. The effective length, neck length and tool overhang should be kept as short as the application allows.
Material Compatibility
| Workpiece Material | Application |
| Stainless Steel | Precision micro milling and deep-feature machining |
| Titanium Alloy | Difficult-to-machine precision applications |
| Hardened Steel ≤50 HRC | Suitable with appropriate cutting conditions |
| Other Difficult-to-Machine Materials | Application dependent |
Actual performance depends on material grade, hardness, tool diameter, effective length, tool overhang, machine rigidity, cutting parameters and cooling conditions.

Dimensional Information
For micro long neck end mills, tool selection should consider:
Micro Long Neck End Mill Selection Guide
Choosing the right 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 tool strength for the application.
Measure the actual machining depth and select an effective length that reaches the feature without unnecessary extension.
The neck should provide sufficient clearance from the workpiece while maintaining adequate structural support.
Use the shortest practical tool setup. Excessive overhang can increase deflection, vibration and the risk of tool failure.
For stainless steel, titanium alloys and hardened steel, adjust cutting conditions according to the material grade, hardness and tool diameter.
Recommended Cutting Conditions
Micro long neck tools require careful control of cutting load, tool overhang and machine stability.

Frequently Asked Questions
What is a 2 flute micro long neck end mill used for?
A 2 flute micro long neck end mill is designed for small, deep and restricted machining features where a standard micro end mill cannot provide sufficient reach.
What is the advantage of the long neck design?
The long neck configuration provides additional clearance behind the cutting section, allowing the tool to reach recessed or deep features while reducing interference with surrounding workpiece surfaces.
Why use a 2 flute micro end mill?
A 2-flute configuration provides greater flute space relative to higher-flute-count designs, making it suitable for small-diameter applications where chip evacuation and controlled cutting conditions are important.
Is the UF(600) suitable for stainless steel?
Yes. Its AlCrN PVD coating provides strong anti-adhesion performance and helps reduce material sticking and built-up edge during stainless steel machining.
