Learn more about Klarna
Description
The Carmex MTB Solid Carbide Thread Mill with Through Coolant is engineered for precision threading in CNC environments, specifically for engineers and machinists who demand clean, accurate 1/8"-27 NPS threads using a rigid MT7 shank.
- Through Coolant Bore: coolant is delivered through the tool bore to flush chips from the hole and keep cutting edges cool, enabling deeper or more complex threads with reduced risk of chip clogging.
- Solid Carbide Construction: premium carbide composition delivers exceptional hardness, wear resistance, and long tool life for high-precision threading in metal workpieces.
- MT7 Morse Taper Shank: robust, repeatable mounting in compatible CNC spindles for improved rigidity and consistent thread quality.
- 1/8" Diameter x 27 TPI (NPS): compact size tailored for small-pitch, National Pipe Straight thread profiles, with reliable engagement and stable flute geometry.
- Optimized Thread Milling Geometry: specifically ground and engineered for precise thread formation, minimal chatter, and smooth finish in a variety of metals.
This through-coolant thread mill helps you achieve reliable, repeatable threads while extending tool life and reducing downtime. Ideal for applications in small-diameter threaded holes, molds and dies, automotive components, and precision fastener work, the Carmex MTB MT7 thread mill delivers disciplined performance, consistent thread accuracy, and a clear path to higher throughput in your milling operations.
