Carmex Thread Mills Solid Carbide - With Through Coolant - UN (UNC UNF UNEF UNS) - 1/2 x 13 - MT7

The Carmex MTB Solid Carbide Thread Mill with Through Coolant is built for professionals who need clean, accurate internal threads in tight bores. Designed for UNC/UNF/UNE...F/UNS thread forms and a 1/2" diameter, 13 TPI, this MT7-shank tool delivers reliable performance in demanding machining environments.

• Through-Coolant Bore: Delivers coolant directly to the cutting edges to improve chip evacuation and thermal control, extending tool life.
• Solid Carbide Construction: Provides high rigidity and wear resistance for precise thread milling in tough materials.
• 1/2" Diameter x 13 TPI: Standard internal thread size for common UNC/UNF/UNE... applications with a clean thread profile.
• MT7 Shank: Compatible with rigid MT7 toolholding for superior rigidity and reduced runout.
• UN/UNC/UNF/UNEF/UNS Thread Forms: Broad compatibility with common internal thread standards.
• Optimized Flute/Geometry: Designed to promote efficient chip evacuation and stable cutting in bore environments.

With coolant flowing through the bore, chips evacuate quickly and heat is removed at the source, enabling deeper pockets, better hole quality, and longer tool life. The solid carbide body resists wear under repeated engagements, delivering consistent thread forms and tighter tolerances over extended production runs. The MT7 shank offers dependable performance on compatible CNC machines, while broad UNC/UNF/UNE... compatibility reduces the need for tool changes and rework. This thread mill is an ideal choice for automotive, aerospace, mold making, and precision threading tasks where reliable internal threads are critical.
