Carmex Mini Type Thread Mills are precision solid carbide tools engineered to create clean, accurate internal threads in hardened materials. Designed for professional machinists and job shops, they deliver reliable performance when working with tough steels and other high-hardness workpieces.
- Material: Solid carbide for exceptional hardness, wear resistance, and long tool life in demanding applications.
- Application: Internal thread milling in hardened materials up to 62 HRc, enabling precise thread formation without tapping.
- Thread Forms: Supports standard UN thread pitches — UNC, UNF, UNEF, and UNS — for broad compatibility with common fasteners.
- Size: 3/8" diameter with 16 threads per inch (3/8 x 16) for small- to mid-size threaded features.
- Shank: MT9 Morse taper shank for secure, rigid tool mounting on compatible milling machines and ATCs.
- Performance: Optimized geometry and carbide construction enable higher cutting efficiency, improved chip evacuation, and a superior surface finish.
This combination of carbide hardness, versatile UN threading capability, and a robust MT9 shank translates into consistent thread quality, reduced cycle times, and fewer rework passes. Whether creating new threads in hardened steel, repairing damaged holes, or producing precision fastener interfaces, these mini thread mills offer dependable results with minimal setup adjustments.
