Carmex Thread Mills Solid Carbide - With Through Coolant - UNJ (UNJC UNJF UNJEF UNJS) - 5/16 x 18 - MT7

The Carmex MTB Solid Carbide Through-Coolant Thread Milling Tool is engineered for precise UNJ threading in demanding materials, delivering cleaner holes, longer tool life, and dependable performance in high‑throughput environments.

• Diameter x Pitch: 5/16" diameter with 18 TPI threads for accurate, repeatable UNJ thread milling
• Shank: MT7 Morse taper shank for secure, versatile mounting in a wide range of milling centers
• Coolant through bore: Integrated through‑bore coolant directs fluid to the cutting zone, enhances chip evacuation, and reduces heat at the point of cut
• Material: Solid carbide construction delivers exceptional rigidity and wear resistance in tough alloys and stainless steels
• Thread Forms Supported: Designed for UNJ, UNJC, UNJF, and UNJS thread standards to accommodate varied engineering specs
• Cutting Geometry: Optimized flute arrangement and edge geometry to produce clean, accurate threads with minimal burrs

Through coolant capability not only streamlines the production of deep or complex threaded holes by sweeping chips out of the bore, but also cools the cutting edges to extend tool life and maintain dimensional accuracy over longer runs. This makes the MTB line a practical choice for precision shops that demand consistent thread quality in challenging materials, from aerospace fasteners to hydraulic components. Expect reliable performance, reduced downtime, and precise UNJ threads with every job.
