Carmex Carbide Thread Mill is a precision tool engineered for fast, reliable M4 x 0.7mm threading in deep holes. Its compact 105 mm length and ISO 3XD mini geometry let you create internal and external threads with a single tool, reducing tooling changes in production.

• Carbide grade & coating: MT7 sub-micron carbide with a TiAlN multi-layer coating (ISO K10–K20) for exceptional wear resistance and low friction.
• High-speed capability: Optimized for medium to high cutting speeds to shorten cycle times while preserving dimensional accuracy.
• Through-coolant design: Coolant delivered through the flutes enhances heat management and enables efficient deep-hole threading.
• Flute geometry: Spiral flutes provide smooth cutting action; 3–5 flutes enable faster material removal and improved chip evacuation.
• Threading versatility: Produces a wide range of thread pitches and works for both internal and external threads with a single tool.
• Deep-hole performance: Short profile reduces cutting forces and vibration, boosting stability in deep-hole applications.
• Material compatibility: Capable of machining hardened materials up to 45 HRc, expanding its versatility across tougher jobs.
• Durability: Triple coating enhances tool life under demanding, repetitive threading tasks.

Designed to boost productivity and reliability, this thread mill delivers repeatable thread forms with fewer tool changes, even in challenging materials. The through-coolant delivery and optimized geometry help maintain tight tolerances in deep-hole work, while the short profile minimizes heat and wear. Ideal for production environments requiring consistent M4 x 0.7mm threads across a variety of parts and materials.
