ø9.00 毫米 12D 整体硬质合金
内冷钻
Designed for oil galleries, tie-rod holes, and structural deep-hole features in forged and cast components. The 12D ratio requires precise machine setup (low runout, rigid fixturing) but delivers repeatable hole straightness well beyond what conventional drills can achieve. Internal coolant is essential at this depth.

这个工具的优点
ø9.00mm 12D — 推荐应用
- ▸ Engine block water jackets
- ▸ Flange bolt-hole patterns
- ▸ Pump housing bore features
- ▸ Railway component deep holes
加工提示: At ø9.00mm the internal coolant channel diameter increases significantly, improving chip flush at deeper ratios. Peck cycles can usually be eliminated.
