Carmex MTB Solid Carbide Through-Coolant Thread Mills are precision tools built for reliable NPS 1/2–3/4 x 14 threading in through-holes. Built on the trusted MT platform, these MTB tools add a cutting-edge through-bore coolant feature to deliver cooling and chip evacuation exactly where you need it.

• Through-coolant bore: Coolant is delivered directly through the tool bore to the cutting edges, improving chip removal and heat control inside the threaded bore.
• Solid carbide construction: Rigid, wear-resistant carbide provides stable threading performance at higher speeds and longer tool life.
• Thread milling geometry: Optimized flute design and geometry for consistent thread profiles and smooth surface finish on through-holes.
• Size and threading: Designed for NPS 1/2–3/4 with 14 threads per inch, ideal for versatile through-hole applications.
• MT7 shank: Standard MT7 shank for secure fit and compatibility with common high-precision milling holders.
• Applications: Perfect for precision thread milling in through-holes across steel, aluminum, and other common machining materials, reducing the need for tapping and enabling efficient production.
• Durability and efficiency: The through-coolant system paired with carbide composition helps extend tool life and maintain consistent thread quality over longer production runs.

These through-coolant thread mills streamline your workflow by improving chip clearance and cooling within the hole, leading to cleaner threads, fewer reworks, and lower tooling costs over time. For shops seeking dependable, high-precision NPS threading in through-holes, Carmex MTB solid carbide tools deliver consistent results with the reliability you expect from a proven MT-series platform.
