The Carmex MTB Solid Carbide Thread Mill with Through Coolant is engineered for precision internal threading in UNC/UNF/UNEF/UNS standards. Designed for CNC operators who demand reliable performance and longer tool life, it delivers sustained accuracy in a compact, rigid package.

• Through coolant bore: coolant fluid runs through the tool to flush chips from the hole and cool the cutting edges, enabling smoother threading and cooler operation.
• Solid carbide construction: a durable, wear-resistant core that maintains tight thread tolerances even in demanding materials and high-speed milling.
• Thread compatibility: supports UN thread forms—UNC, UNF, UNEF, UNS—in a 3/8" diameter with 16 TPI for versatile fastening standards.
• MT7 shank: designed to fit standard Morse Taper 7 holders for rigid, stable mounting on compatible machines.
• Optimized threading geometry: tailored geometry for efficient thread milling, delivering accurate thread profiles with clean bottoms.

The MTB line’s through-bore cooling brings tangible benefits: improved chip evacuation reduces the risk of built-up edge, heat-related wear, and chatter, while extended tool life lowers replacement costs and downtime. This makes the Carmex MTB thread mill a dependable choice for production runs and precision prototyping alike, delivering consistent thread quality from the first pass to the last.
