The Carmex MTZ Through-Coolant Thread Mill (MT7) is a carbide tool built for precision threading in through-hole applications. As part of the MTZ range, it delivers coolant directly through the flutes to the cutting edge, enabling smoother cuts and reliable chip evacuation.

• Through-Coolant Flutes: coolant is delivered internally to the cutting edge for efficient heat removal, reduced thermal distortion, and cleaner thread profiles.
• Carbide Construction: rigid, wear-resistant carbide provides long tool life and maintains tight tolerances under demanding machining conditions.
• Through-Hole Threading Focus: optimized geometry supports threading through holes with direct chip removal, improving productivity and finish consistency.
• UN Thread Compatibility: designed to cut common United Nations thread forms (UNC, UNF, UNEF, UNS) in a precise 7/16-14 size.
• MT7 Shank: compatible with standard MT7 holders for broad machine compatibility and secure, vibration-minimizing seating.

This thread mill is ideal for shops that need dependable, accurate threading in through-hole work without relying on external coolant systems. The combination of through-flute cooling, robust carbide construction, and a tailored thread-form geometry delivers consistent thread quality, easier tool life management, and improved process reliability across a range of materials and depths.
