The Carmex Thread Mills Solid Carbide with Through Coolant (MTB line) is a precision metric thread milling tool engineered for CNC production. It delivers reliable, accurate threads with the advantage of coolant flowing directly through the bore to the cutting zone for better heat management and chip control.
- Threading range: Metric threads from M14 to M18 x 1.5, covering a wide range of common threading applications.
- Through coolant bore: Integrated coolant path feeds coolant through the tool to the cutting edges, improving cooling and debris removal in deep-hole threads.
- Solid carbide construction: High rigidity and wear resistance for consistent thread quality and longer tool life.
- MT7 shank: Designed for compatibility with MT7 tool-holding systems on compatible CNC machines.
- Tubular cooling efficiency: Through-coolant design reduces heat buildup and minimizes built-up edge, supporting repeatable tolerances over many cycles.
With through-coolant threading, you get cleaner holes, more predictable thread dimensions, and lower maintenance costs in high-volume production. This tool is ideal for shops that require durable, precise metric threads and efficient chip evacuation in a single, robust carbide cutter.
