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.

可订购标准系列覆盖直径 D1、D2、D3、D4、D5、D6、D8、D10 和 D12。球头半径等于切削直径的一半：例如 D6 对应 R3。柄径遵循 Qeviora 标准矩阵（D1–D3 → d4；D4–D5 → d6；自 D6 起 → 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.

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.

How to choose

A progressive selection reduces unnecessary trials and protects the tool.

  1. 01Identify the main ISO material group (P, M, K, N, S, H).
  2. 02Select the matching visual family and check validation status.
  3. 03Start from indicative D6 | R3 values, then adjust for rigidity, overhang and engagement.
  4. 04Avoid permanent centre-cutting of the ball during 3D finishing.
  5. 05Confirm by trial before industrialisation.

Technical warning: illustrated visuals, coatings and cutting parameters are indicative only. They are not a performance guarantee, a commercial equivalence with another manufacturer, or final validation without machine trials.
