Carmex Thread Mills Mini Type - Through Coolant (MT7) is a compact solid carbide thread milling cutter designed for precise M4 x 0.7 threads in tight pre-holes. Its integrated through-coolant bore delivers high-pressure coolant directly to the cutting edge, improving cooling and chip evacuation during threading.

• Tool Type: Solid carbide thread milling cutter (Mini Type, MTSB) with an internal through-coolant bore
• Size / Thread: Metric M4 x 0.7 threading for small-diameter holes
• Coolant System: Through-coolant bore provides high-pressure coolant to the pre-hole and washes chips away during the threading circle
• Material: High-hardness solid carbide for wear resistance and precision
• Shank: MT7 (Morse Taper 7) compatibility for secure, accurate mounting
• Designed for Precision Thread Milling: Optimized geometry to achieve clean, consistent threads in challenging materials

The through-coolant design not only cools the cutting edge more effectively but also enhances chip removal, helping maintain thread accuracy and extending tool life. Its compact Mini Type form fits into restricted cavities and cores while delivering reliable M4 x 0.7 threads, making it ideal for molds, electronics housings, and precision assemblies where space is at a premium and thread integrity is critical.
