Carmex Mini Type Thread Mills are precision carbide tools designed for high-speed thread milling in tight spaces. This MJ 5 x 0.8 MT7 version is built for deep-hole work and delivers reliable internal and external threading across a broad range of materials.

  • Tool type and size: Mini-type carbide thread mill, MJ 5 x 0.8 with MT7 shank
  • Coating and grade: MT7 sub-micron carbide with a TiAlN multi-layer coating (ISO K10–K20) for durability at elevated speeds
  • Threading versatility: Produces both internal and external threads across a wide pitch range with a single tool
  • Deep-hole capability: Through-flute coolant and spiral geometry enable effective threading in deep holes
  • Flute design and count: Spiral flutes, 3–5 flutes for smooth cutting and shorter cycle times
  • Cutting performance: Optimized for medium to high cutting speeds to maximize productivity
  • Material tolerance: Capable of machining hardened materials up to 45 HRC
  • Tool life: Special triple coating extends life, reducing tool changes and downtime
  • Cutting forces: Short profile lowers cutting forces for improved stability and reduced risk of breakage
  • Coolant through flutes: Internal coolant channels enhance cooling and chip evacuation in challenging features

Designed for engineers who demand reliable, accurate threads in a variety of materials and hole depths, this tool delivers consistent thread quality with minimal setup changes. Its deep-hole threading capability, combined with the ability to cut both internal and external threads, makes it a versatile addition to automotive, aerospace, hydraulic, and mold-manufacturing workflows. With a robust carbide construction and advanced coating, you can expect longer tool life, reduced cycle times, and dependable performance on demanding projects.
