Carmex MTSB Mini Type Through-Coolant Thread Milling Cutter is a compact, solid carbide tool designed for precise metric internal threads (M10 x 1.5) with an MT7 shank. Built for through‑coolant efficiency, it delivers coolant directly through the tool to the pre-hole, helping you achieve cleaner threads and steady cutting performance.

- Through‑coolant bore: internal coolant channel delivers high-pressure coolant through the tool into the pre-hole, aiding chip evacuation and cooling during the threading circle.
- Solid carbide construction: robust cutting edges provide long tool life and consistent thread quality across challenging materials.
- Mini Type geometry: compact profile optimized for tight pockets and small-diameter threads without compromising rigidity.
- Metric thread size: precisely machined M10 x 1.5 threading capability with MT7 shank for broad machine compatibility.
- Efficient chip control: through-coolant delivery helps keep chips moving and heat away from the cutting edge, supporting stable finishes and reduced rework.
Using the Carmex mini thread mill with through coolant enables higher cutting speeds and deeper threads with fewer interruptions due to chip clogging. The combination of precise metric threading, durable carbide, and effective coolant delivery makes it well suited for automotive, aerospace, and general precision machining where reliable internal threads and clean finishes are essential.
