Learn more about Klarna
Description
The Carmex MJ 3 x 0.5 MT7 Carbide Mini Thread Mill is a compact, all-purpose threading tool designed for precise internal and external threads across a wide range of materials, including hardened alloys. Optimized for medium to high cutting speeds, it delivers efficient, reliable threading with a short profile that reduces cutting forces.
- Tool type and size: Mini carbide thread mill with MJ 3 x 0.5 dimensions and MT7 shank for versatile CNC threading operations.
- Carbide grade and coating: MT7 sub-micron carbide with a TiAlN multi-layer coating (ISO K10–K20) for superior wear resistance and long tool life.
- Flute design: Spiral flutes with a short profile and 3–5 flutes for smooth cutting action and efficient chip evacuation.
- Coolant through flutes: Through-coolant capability enhances cooling and debris removal in deep holes, improving surface finish and tool longevity.
- Threading versatility: Supports a wide range of thread sizes and pitches, and can produce both external and internal threads with a single tool.
- Cutting performance: Ready for medium to high cutting speeds, enabling shorter machining times without sacrificing thread accuracy.
- Material reach: Suitable for general-purpose threading across materials and capable of machining hardened materials up to 45 HRc.
- Durability and reliability: Short profile reduces cutting forces and stress, lowering the risk of breakage; triple coating further extends tool life.
This tool is ideal for precision parts where space is limited and rapid, accurate threading is required—from housings and connectors to components that demand both internal and external threads. The MT7 carbide mini thread mill combines deep-hole threading capability with robust performance, delivering clean threads, reduced cycle times, and reliable operation across a broad material spectrum.
