Carmex Carbide Thread Mills - ISO 3XD Mini Type - M4 x 0.7mm (58mm length)

Compact, high-precision carbide thread mills built for deep-hole threading in tight work envelopes. Designed for professionals who demand reliable internal and external threads, this 58 mm ISO 3XD Mini Type tool delivers consistent results in challenging geometries.

• Thread size & length: M4 x 0.7 mm thread form, ISO 3XD mini type, with a 58 mm overall length optimized for deep-hole work
• Carbide grade & coating: MT7 Sub-Micron carbide with a titanium aluminium nitride multi-layer coating (ISO K10–K20) for improved wear resistance and heat tolerance
• Through-coolant design: Coolant-through flutes enhance cooling and chip evacuation during deep-hole threading
• Flute geometry: Spiral flutes ensure smooth cutting action and stable engagement
• Flute count: Multi-flute configuration (3–5 flutes) reduces machining time and distributes cutting loads
• Versatility: A single tool capable of a wide range of thread sizes and pitches, cutting both internal and external threads
• Performance with hard materials: Suited for hardened workpieces up to 45 HRc with lower cutting forces thanks to the short profile
• Durability: Triple-coated surface and advanced coating extend tool life in demanding applications
• Recommended cutting speeds: Optimized for medium to high cutting speeds to shorten cycle times

This thread mill combines a compact mini form with an advanced coating and a robust carbide core to deliver precise thread profiles quickly, even in deep holes. Its ability to cut both internal and external threads with through-coolant reduces setup complexity and improves reliability on challenging workpieces. Ideal for precision manufacturing in automotive, aerospace, and moldmaking, it helps shorten cycle times, extend tool life, and minimize tool changes without compromising accuracy.
