A 3-piece set of metric MT7 thread mills engineered for long‑reach, through‑coolant threading. Designed to tackle medium to large threads in deep workpieces—even features located at the base of the part—these tools deliver precision without compromising productivity.

• Set of 3 metric MT7 thread mills: A ready-to-use 3‑piece selection optimized for high‑demand threading tasks.
• Long‑reach design: Extended reach to access deep pockets, base features, and hard‑to‑reach threads without excessive workpiece repositioning.
• Through‑coolant bore: Internal coolant delivers coolant directly to the cutting zone for improved chip control and tool life.
• Thread length up to 3D: Capable of threading lengths approaching three times the major diameter, boosting throughput on deep or lengthy threads.
• High rigidity and stability: Robust construction minimizes vibration, enabling accurate thread forms at higher speeds and feeds.
• Low cutting forces: Short cutting length reduces bending moment and chatter, promoting better surface finish and longer tool life.
• MT7 shank compatibility: Designed to fit common MT7 tool holders, ensuring secure retention and consistent performance across setups.

This long‑reach, through‑coolant threading solution is ideal for automotive, aerospace, and moldmaking applications where you need precise, reliable internal threads in deep or base‑level features. By combining rigidity, extended reach, and efficient coolant delivery, the tools help you reduce cycle times, improve dimensional accuracy, and simplify setups—even when clearance is limited. Use with appropriate feeds, speeds, and coolant pressure to maximize tool life and achieve consistent thread quality across complex workpieces.
