Solid carbide ball nose end mills
Solid Carbide Ball Nose End Mills
Qeviora solid carbide ball nose end mills are designed for 3D surface machining, complex contours, radii, moulds, dies and components requiring a consistent surface finish. Their hemispherical cutting end supports contour milling, semi-finishing, finishing and machining of difficult-to-reach areas.
La gamma standard ordinabile copre i diametri D1, D2, D3, D4, D5, D6, D8, D10 e D12. Il raggio sferico è pari alla metà del diametro di taglio: ad esempio, D6 corrisponde a R3. Il diametro del gambo segue la matrice standard Qeviora (D1–D3 → d4; D4–D5 → d6; da D6 → d = D).
All cutting values shown on the website must be identified as indicative starting values. They must be adjusted according to the exact workpiece grade and hardness, holder, runout, tool overhang, machine rigidity, toolpath, radial and axial engagement, and cooling strategy.

Applications
3D machining and contour finishing
Select the family by material and operation. Images illustrate ball-nose geometry; they do not replace shop-floor validation.
- 3D surfaces and complex shapes
- Moulds, dies and cavities
- Contours, radii and semi-finishing
- Consistent finishing in difficult-to-reach areas
Cutting conditions
Indicative starting values — tool D6, R3
Conservative starting ranges for a D6 ball nose with low to moderate radial engagement. Confirm by trial.

| Titanium and Heat-Resistant Alloys | S | 35–70 | 0,010–0,025 | 2–6 % D | 0,05–0,20 D | Abundant, reliable coolant |

In ball-nose milling, effective cutting speed decreases toward the tool centre. For 3D finishing, prefer tool tilt or a toolpath that avoids continuous centre cutting.

Method
How to choose
A progressive selection reduces unnecessary trials and protects the tool.
- 01Identify the main ISO material group (P, M, K, N, S, H).
- 02Select the matching visual family and check validation status.
- 03Start from indicative D6 | R3 values, then adjust for rigidity, overhang and engagement.
- 04Avoid permanent centre-cutting of the ball during 3D finishing.
- 05Confirm by trial before industrialisation.
