Carmex Thread Mills Solid Carbide - With Through Coolant - UNJ (UNJC UNJF UNJEF UNJS) - 7/16 x 14 - MT7

Carmex MTB Solid Carbide Thread Mill with Through Coolant is a precision internal-threading solution designed for engineers and machinists who demand clean, accurate UNJ threads and extended tool life. Built for through-coolant operation, this tool delivers improved chip evacuation and cooling directly at the cutting edge.

• Thread Form Compatibility: Supports UNJ variants (UNJC, UNJF, UNJEF, UNJS) for versatile internal threading across common standards.
• Size & Shank: 7/16"-14 internal thread milling size with MT7 shank, compatible with standard CNC tool holders.
• Material: Solid carbide construction provides high stiffness, wear resistance, and precision in demanding applications.
• Through-Coolant: Coolant is delivered through the bore to the cutting edges, aiding chip evacuation and edge cooling.
• Flute Geometry: Optimized flute design for stable, smooth cutting in deep, precise holes.
• Application Range: Ideal for high-precision internal threading in aerospace, automotive, and mold-making components.
• Durability & Longevity: Through-coolant operation reduces heat buildup, helping extend tool life and reduce downtime.

This thread mill enables consistent, burr-free UNJ threads with fewer reworks and tighter tolerances. The through-coolant design keeps chips moving, minimizes thermal distortion, and supports reliable performance across production runs. Pair it with your existing MT7 tooling setup to enhance internal threading efficiency and overall manufacturing uptime in precision environments.
