The Carmex MTZ Thread Mills Carbide with Through Coolant is a precision threading tool designed for through-hole applications. Built for shops that demand reliable, coolant-assisted cutting directly at the edge, it delivers consistent, high-quality threads with efficiency.

• Through-Coolant Flute Design: Coolant feeds through the tool’s flutes to the cutting edge for enhanced cooling, washout control, and smoother thread formation.
• Carbide Construction: Hard-wearing carbide substrate provides excellent edge strength and long tool life in demanding threading jobs.
• Thread Form Compatibility: Optimized for UNC, UNF, UNEF, and UNS through-hole threads, including the 9/16 x 12 size.
• Size & Shank: Diameter 9/16" with 12 TPI threading, mounted on an MT7 shank for broad compatibility with common toolholders.
• Direct Chip Removal: Through-hole threading geometry enables efficient chip evacuation, reducing buildup and improving surface finish.
• Machine Compatibility: Ideal for machines without external coolant systems, enabling through-coolant capability even in streamlined setups.

This MTZ thread mill excels in industries that require dependable internal threading, such as aerospace, automotive, and precision manufacturing. By delivering coolant directly to the cutting edge and enabling efficient chip removal, it helps you achieve clean, consistent threads with fewer passes and less downtime. The MT7 shank integrates smoothly with existing toolholding setups, making it a practical upgrade for threaded through-hole operations that value precision and reliability.
