Introducing Carmex MTB Solid Carbide Thread Mills with Through Coolant — a precision solution for internal threading in metalworking. Built for machinists who demand durability and consistent accuracy, these MT7 shank tools elevate thread milling performance in demanding holes.

• Material: Solid carbide construction delivers high hardness, wear resistance, and extended tool life in tough alloys.
• Through coolant: Internal bore delivers coolant directly to the cutting edge, improving chip evacuation and reducing heat for cleaner, more consistent threads.
• Thread size: Metric M12 x 1.75 threading capability for precise, standardized internal threads.
• Shank: Morse Taper 7 (MT7) shank provides secure, repeatable seating in compatible holders.
• Design purpose: Optimized geometry for stable thread milling and efficient material removal in a range of metal substrates.

The MTB line’s through-bore cooling combines efficient chip control with enhanced tool longevity, helping you reduce downtime and improve thread quality in production or precision projects. Its robust carbide construction and MT7 compatibility make it a dependable choice for high-precision internal threading tasks in industries such as aerospace, automotive, and general engineering.
