Engineered for deep, demanding threading, Carmex Long Reach Through Coolant thread mills are part of the MTQ family, delivering precision for metric threads in deep pockets and base features. Ideal for machinists tackling medium to large threads where access is limited.

• Long reach through coolant design: Extended reach with an internal coolant channel to reach deep features while directing coolant and flushing chips away from the cut.
• MT7 shank interface: Optimized for MT7 tool holders to maximize rigidity and stability during high‑speed threading.
• High rigidity and stability: Robust construction minimizes vibrations, enabling cleaner thread profiles and more consistent dimensions.
• Thread lengths up to 3D: Capable of threading relatively deep features, expanding usable applications without additional setups.
• Internal coolant bore: Through‑coolant capability keeps the cutting edge cool and improves chip evacuation for longer tool life.
• Overhang tolerance: Designed to handle overhangs, increasing versatility in setups where access is constrained.
• Low cutting forces: Short effective cutting length helps keep cutting forces manageable and reduces tool deflection even in longer reach operations.

When you need reliable internal threading in hard‑to‑reach locations, these Carmex thread mills provide consistent performance from first cut to last. The combination of through‑coolant delivery, MTQ‑designed rigidity, and a long reach translates to higher productivity, better surface finish, and fewer reworks on deep holes across automotive, aerospace, mold making, and hydraulic components. Maintain thread quality and improve cycle times by leveraging the tool’s ability to sustain higher speeds and feeds without sacrificing accuracy.
