Carmex Thread Mills Carbide - Through Coolant (Flutes) - G (55 Degree) BSF BSP - x 16 - MT7

Meet the Carmex MTZ thread mill—a carbide threading tool engineered for through-hole applications. This MT7-grade cutter delivers coolant through the flutes to the cutting edge, enabling smoother, more reliable internal threads in metal parts. Designed for machinists who demand precision and throughput, it excels in through-hole threading scenarios while keeping setups lean where external coolant lines aren’t available.

• Tool Material: Solid carbide construction delivers high wear resistance and consistent thread accuracy across production runs.
• Through-Coolant Flutes: Internal coolant is conveyed through the flute channels directly to the cutting edge for improved cooling and chip evacuation.
• Thread Form: G family with a 55° profile, compatible with BSF and BSP standards for reliable through-hole threading.
• Designed for Through-Hole Threading: Specifically optimized for threading through holes with direct chip removal to minimize clogging.
• Machine Compatibility: Ideal for machines without external coolant, enabling efficient threading in lean tooling environments.
• Interface: MT7 shank ensures robust engagement with common CNC holders and high rigidity during cut-and-thread operations.
• Size: x 16 (as specified in the product title), paired with MT7 for precise, stable cutting action.

The MTZ family, including this G 55° BSF BSP variant, is crafted for clean thread finish, long tool life, and dependable performance in demanding throughput scenarios. By delivering coolant directly through the flutes and focusing on through-hole threading, it minimizes heat buildup, reduces thread runout, and lowers cycle times compared with traditional through-coolant approaches. This makes it especially well-suited for hydraulic, pneumatic, and automotive components that require precise BSP/BSF threads in through-holes.
