# Tapered Ball Nose Endmill (Ø0,5-4mm)

### **What it is**

A tapered ball nose endmill combines a **conical taper** with a **ball-shaped tip**.\
The taper increases stiffness, while the ball tip allows smooth, continuous surface machining.

This geometry is commonly used where **fine detail, surface quality, and tool reach** matter more than material removal rate.

***

### **What it’s used for**

* 3D surface finishing
* Sculpted geometry and organic shapes
* Fine detail work
* Mold-like surfaces and reliefs

***

### **Why tapered geometry matters**

Compared to straight ball endmills of the same tip diameter:

* The **larger shank and taper** significantly reduce deflection
* Small tip diameters become usable at greater depths

***

### **Key Features to Look For**

| Feature                            | Why it matters (for compact CNCs)                    |
| ---------------------------------- | ---------------------------------------------------- |
| **Tip diameter range (Ø0.5–4 mm)** | Enables fine detail and smooth surface finishing     |
| **Tapered body**                   | Increases stiffness and reduces deflection           |
| **2 flutes**                       | Balanced cutting forces and reliable chip evacuation |
| **Solid carbide**                  | Maintains edge sharpness and rigidity                |
| **Anti-BUE coating**               | Reduces aluminium adhesion during dry cutting        |
