The Carmex MTB Solid Carbide Thread Mills with Through Coolant are designed for precise UN/UNC/UNF/UNEF/UNS thread milling in metal parts. Built for professional shops, this through-coolant tool enhances chip evacuation and extends tool life in demanding machining environments.

• Size/Shank: Diameter range 1 1/8 in to 1 1/4 in, flute length 7 in, MT7 taper for secure, rigid mounting.
• Material: Solid carbide for exceptional rigidity, wear resistance, and tight tolerance retention across multiple passes.
• Through-Coolant: Internal coolant bore delivers coolant directly to the cutting edges, aiding chip removal and reducing heat buildup for cleaner holes.
• Thread Forms: Compatible with UN, UNC, UNF, UNEF, and UNS thread types for versatile production of common imperial and metric threads in metal.
• MTB Line Advantage: Part of Carmex MTB family, engineered to maximize performance with integrated cooling and durable geometry for precision threading.

This tool improves hole quality and extends tool life by effectively managing heat and swarf. The through-coolant design enables higher cutting speeds with fewer interruptions from chip buildup, delivering consistent thread profiles and reducing downtime in production runs. Ideal for aerospace, automotive, and precision machining applications where reliable UN-threading is a routine requirement.
