Carmex MTZ carbide thread mills with through coolant are precision tools designed for threading through holes with clean, accurate Whitworth BSF/BSW profiles. Built for reliability in industrial threading tasks, they deliver coolant directly to the cutting edge for smoother cuts and extended tool life.

• Through-Coolant Flutes: coolant travels through the flute channels directly to the cutting edge, improving heat control and flushing chips away during through-hole threading.
• Carbide Construction: rigid, wear-resistant carbide body for precise thread formation and long tool life in challenging materials.
• Thread Forms: specifically engineered for Whitworth BSF/BSW threading, delivering accurate profiles on through-holes.
• MT7 Shank: compatible with a wide range of milling machines, offering secure, rigid toolholding for high-speed threading operations.
• Through-Hole Thread Milling: optimized for direct chip removal from through holes, reducing clogging and improving process reliability.
• Size and Pitch: tailored for 1/2" to 9/16" nominal threads with 16 TPI, matching common Whitworth specifications.

This MTZ thread mill is well suited for shops that need dependable through-hole threading without relying on external coolant systems. The through-coolant design minimizes heat buildup at the cutting edge, supports consistent thread quality, and helps maintain tight tolerances across varying materials. Ideal for precision manufacturing environments where through-hole threading, chip evacuation, and durable carbide tooling matter most.
