Carmex MTB Solid Carbide Thread Mills with Through Coolant deliver precise NPTF internal threads while keeping chip control and tool life at the forefront. Built for demanding production environments, these tools are ideal for shops needing reliable, high-precision threading in deep or intricate holes.

• Through-Coolant bore: Coolant is delivered directly through the cutting bore, enhancing chip evacuation and cooling at the point of cut for cleaner threads and cooler operation in challenging materials.
• Solid carbide construction: Rigid, wear-resistant carbide provides stable, accurate threading and extended tool life in demanding metals.
• NPTF internal threading: Specifically designed to produce precision NPTF threads, enabling tight tolerances for pipe fittings, hydraulics, and fluid systems.
• MT7 shank: High-rigidity MT7 shank ensures strong torque transmission and compatibility with premium CNC milling centers for consistent hole quality.
• MTB line innovation: Part of Carmex’s MTB thread mill family, combining efficient coolant delivery with robust cutting geometry to maximize uptime and reduce rework.
• Dimensions: Size 1 - 2 x 11.5 with through-coolant capability and MT7 connection for compact, repeatable deployments.

The integrated through-coolant design minimizes heat buildup and enables reliable chip removal, which translates to smoother finishing passes, fewer reworks, and longer tool life. This makes the Carmex MTB thread mills a practical choice for high-volume production lines where consistent thread quality and reduced maintenance matter most.
