Carmex’s MT7 carbide thread mill with through coolant is engineered for precise threading in through-hole applications, delivering coolant directly to the cutting edge for smooth, efficient operation. Ideal for shops seeking reliable, high-precision threads in metal parts, even on machines without external coolant systems.

• Through-Coolant Flutes: coolant travels along the flute channels directly to the cutting edge, enabling higher cutting speeds, reduced heat, and improved chip evacuation for cleaner threads.
• Carbide Construction: a hard, wear-resistant substrate that maintains sharpness for durable, repeatable threading across steel, stainless, and aluminum alloys.
• Through-Hole Threading Design: optimized for threading through holes with direct chip removal, minimizing chip packing and simplifying cycle times.
• UN/UNC/UNF/UNEF/UNS Compatibility: supports a wide range of standard thread forms to cover common engineering requirements.
• Size & Shank: 7/16 in diameter with a 10 in length and an MT7 Morse Taper shank for broad machine compatibility.
• MTZ-Style Cooling Advantage: integrated cooling through the flutes enhances process stability and part quality, even in challenging materials.
• Direct Chip Removal: designed to evacuate chips efficiently from through-holes, reducing re-cutting and improving surface integrity.

This Carmex thread mill enables precise, consistent thread formation with enhanced heat management and efficient chip control. It’s a practical choice for industries that require dependable through-hole threading—automotive, aerospace, and general manufacturing—where access to external coolant may be limited or absent. Expect strong performance, longer tool life, and stable thread quality across a range of standard thread forms.
