The Carmex Carbide Mini Type Thread Mill with MT7 shank is a compact, high-performance threading tool designed for small-diameter holes. Ideal for precision shops and engineers, it delivers clean M3 x 0.5 threads in a wide range of materials while thriving in tight spaces.

• Grade and coating: MT7 sub-micron carbide with a TiAlN multi-layer coating (ISO K10–K20) for exceptional wear resistance and longer tool life.
• Threading versatility: One tool can produce both internal and external threads across multiple pitches, simplifying setups and reducing tool changes.
• Size and spec: Metric size M3 x 0.5 with MT7 shank, designed for compatibility with compact fixtures and holders.
• Through-coolant design: Coolant-through flutes provide efficient cooling and chip evacuation, especially in deep-hole applications.
• Flute geometry: Spiral flutes deliver smooth cutting action, with a multi-flute configuration (3–5 flutes) that shortens machining time.
• Short profile: Compact profile reduces cutting forces, improving stability and finish in confined work areas.
• Material capability: Suitable for a broad range of materials and capable of machining hardened materials up to 45 HRc.
• Durability: Special triple coating enhances tool life, maintaining edge quality over long production runs.

This thread mill equips you to achieve precise, repeatable threads with reduced risk of tap breakage and shorter cycle times. The through-coolant system and compact geometry make it particularly effective for deep-hole threading and high-speed operations, delivering reliable performance from first run to last.
