Experience reliable, high-precision internal threading with Carmex MTB Thread Mills. Designed for machinists and engineers working with UNC/UNF/UNEF/UNS thread forms, these through-coolant solid carbide tools deliver clean threads and extended tool life.

• Diameter x Thread Pitch: 1/4" nominal diameter with 20 TPI for UNC/UNF/UNEF/UNS thread forms
• Through-Coolant Bore: coolant is delivered through the bore to flush chips and cool cutting edges, improving chip evacuation and surface finish
• Material: Solid carbide construction for exceptional hardness, wear resistance, and long tool life
• Shank: MT7 Morse Taper shank for secure, quick-change compatibility with compatible CNC spindles
• Threading Capability: engineered specifically for internal threading using UNC, UNF, UNEF, and UNS standards
• Application Focus: optimized for precise, repeatable thread milling in through holes and blind holes alike

With through-coolant threading, you gain reliable chip clearance and consistent heat control, which translates to cleaner thread forms and fewer rework cycles. The combination of solid carbide strength and an MT7 shank offers dependable performance in demanding materials and tight tolerances. This tool is well-suited for shops producing fasteners, housings, and precision components where durable tooling and precise thread accuracy matter most, helping you reduce downtime and extend tool life without compromising on thread quality.
