Carmex Thread Mills Carbide Mini Type - Metric - M2.5 x 0.45 - MT7 - Long - 5.5mm Reach

The Carmex Thread Mills Carbide Mini Type is a precision carbide thread mill designed for small-diameter internal and external threads. With an MT7 shank, metric M2.5 x 0.45 pitch, and a 5.5 mm reach, it excels in deep-hole threading at medium to high cutting speeds.

• Thread mill type: Mini carbide tool for internal and external threads on small diameters
• Size and pitch: Metric M2.5 x 0.45
• Reach: 5.5 mm long reach for deep holes
• Shank: MT7 solid carbide shank
• Coating: Sub-micron MT7 with Titanium Aluminium Nitride multi-layer coating (ISO K10–K20)
• Flute design: Spiral flutes for smooth cutting; 3–5 flutes for shorter machining time
• Coolant: Through-the-flutes coolant for efficient cooling in deep-hole threading
• Material capability: Suitable for all materials, including hardened steels up to 45 HRc
• Performance: Optimized for medium to high cutting speeds with lower cutting forces due to the short profile
• Versatility: One tool can produce a wide range of threads and pitches; suitable for both internal and external threads

Using this tool reduces machining time and setup changes while delivering accurate, consistent thread profiles in challenging materials. The through-coolant system supports deep-hole threading by cooling and flushing chips away from the cutting zone, and the TiAlN coating extends tool life in demanding environments. This makes it ideal for precision components in aerospace, automotive, and general mechanical applications where reliable, repeatable thread quality matters.
