Compact and precise, the Carmex Thread Mills Mini Type Through Coolant is designed for small-diameter metric threading. Ideal for tight spaces and automated milling, it delivers clean M4 x 0.7 threads with efficient chip control and edge cooling.

• Tool type: Mini solid carbide thread mill (MTSB type) with an internal cooling bore for through-coolant delivery.
• Thread specification: Metric M4 x 0.7 threading, suitable for compact, high-precision holes.
• Material: Solid carbide for exceptional wear resistance and dimensional stability during cutting.
• Internal coolant bore: Through-tool coolant provides high-pressure flow directly to the pre-hole and threading zone, improving chip evacuation.
• Shank style: MT7 shank compatibility for secure fit in standard milling machines and holders.
• Chip evacuation: Coolant-assisted cutting washes chips away during the threading circle, reducing chip packing in the flute.
• Edge cooling: Direct coolant cooling helps maintain a sharp cutting edge and uniform surface finish.

By combining through-coolant delivery with a robust carbide core, this mini thread mill delivers reliable, repeatable M4 x 0.7 threads even in demanding materials. The through-coolant system minimizes heat, lowers tool wear, and supports stable feeds in CNC milling cycles, making it a solid choice for precision threading in metalworking environments where space is limited and chip control is critical.
