Micro Diameter Design
Small diameter geometry enables machining of miniature features and narrow structures that require high precision.
2-Flute / 4-Flute Configuration
Different flute configurations allow customers to balance chip space, cutting efficiency and surface finish requirements according to machining applications.
Solid Carbide Substrate
High-quality carbide provides suitable hardness and rigidity for precision miniature cutting applications.
Precision Ground Cutting Edge
Precision grinding helps maintain cutting-edge consistency and improve machining stability.
2-Flute and 4-Flute Configuration Options
Flute count should be selected according to the workpiece material, machining feature, chip volume, cutting engagement and required surface finish. ZHY micro diameter square end mills are available in 2-flute and 4-flute configurations for different precision machining requirements.
2-Flute Micro End Mills
- Larger flute space for chip evacuation

- Supports stable cutting in small-diameter applications
- Suitable for applications where chip clearance is a priority
4-Flute Micro End Mills
- More cutting edges during machining
- Suitable for side milling and finishing operations
- Supports higher cutting-edge engagement
- Suitable when chip evacuation is less restrictive
- Helps achieve stable surface quality under suitable conditions
Coating Options for Different Workpiece Materials
Micro diameter end mills can be supplied with different surface configurations according to the workpiece material, machining conditions and tool-life requirements. Coating selection should be confirmed together with cutting-edge geometry rather than by coating alone.
For Non-Ferrous and Low-Adhesion Cutting
- Sharp cutting-edge geometry is prioritized
- Smooth chip flow helps reduce cutting resistance
- Suitable surface configurations can be selected according to the alloy
- Recommended for applications requiring clean cutting and fine features
- Tool specification can be adjusted according to machining conditions
For Steel and Higher-Wear Applications
- Coating can be selected according to material hardness
- Wear and thermal resistance become more important
- Tool geometry should maintain sufficient cutting-edge strength
- Suitable for precision machining requiring stable tool life
- Custom coating configurations are available according to application requirements

Micro End Mill Selection and Application Notes
Because micro diameter tools have lower cross-sectional rigidity than larger end mills, tool selection and machining conditions should be confirmed carefully before production.
Tool Selection
- Select only the cutting length required by the feature
- Use the shortest practical tool reach whenever possible
- Choose 2 or 4 flutes according to chip evacuation and machining operation
- Match cutting-edge geometry to the workpiece material
- Confirm the required slot width and feature dimensions before ordering
Machining Stability
- Maintain low spindle and toolholder runout
- Use rigid toolholding and stable workpiece clamping
- Avoid excessive radial or axial cutting engagement
- Provide reliable chip evacuation around small features
- Use suitable cutting parameters for the actual tool diameter
