Carmex Thread Mills Solid Carbide - With Through Coolant - UNJ (UNJC UNJF UNJEF UNJS) - 7/16 - 1/2 x 20 - MT7

The Carmex Thread Mills Solid Carbide with Through Coolant is a high-precision threading tool built for UNJ threads (UNJC, UNJF, UNJEF, UNJS). Designed for through-hole applications, it delivers reliable chip evacuation and extended tool life in demanding machining environments.

• Cutting Diameter: 7/16" cutting diameter for precise UNJ threading.
• Thread Form Compatibility: Supports UNJ family including UNJC, UNJF, UNJEF, and UNJS profiles.
• Through-Coolant Bore: Internal coolant delivery directly to the cutting edges for superior chip control and heat management.
• Shank Type: MT7 shank provides robust toolholding and stability on heavy-duty machines.
• Material: Solid carbide construction offers high hardness, wear resistance, and repeatable accuracy.
• Thread Size: Produces 1/2"-20 UNC threads with UNJ geometry for reliable fit and performance.

Using through-coolant capability, this tool maintains cleaner holes and quieter tooling cycles, enabling higher feeds and longer runs between rework. The combination of solid carbide hardiness and MT7 stabilization translates to consistent thread quality, reduced tool wear, and lower total tooling costs in precision manufacturing—whether you’re threading fasteners for aerospace components, automotive assemblies, or complex machinery housings. For engineers seeking dependable UNJ thread mills that maximize uptime and maintain tight tolerances, this Carmex tool is a purpose-built solution designed to perform under demanding production conditions.
