Learn more about Klarna
Description
The Carmex Thread Mills Solid Carbide with Through Coolant (MJ 6 x 1, MT7) is a precision thread milling tool designed for reliability in metalwork. Built for professional shops that need clean, accurate threads with efficient chip removal, it delivers consistent results in demanding applications.
- Through-Coolant Bore: coolant is delivered through the tool bore to the cutting edges, enhancing cooling and flushing chips out of the hole for smoother, uninterrupted threading.
- Solid Carbide Construction: a rigid, wear-resistant body that maintains sharpness and dimensional stability over many cycles for repeatable thread quality.
- MT7 Shank: robust taper fit for precise seating in standard tool holders, minimizing runout and promoting repeatable performance in high-speed milling setups.
- Thread Milling Capability (MJ 6 x 1): specifically engineered to produce 6 × 1 metric threads, suitable for internal and external threading operations with reliable pitch accuracy.
- Optimized Flute Geometry: multi-flute design and cutting-edge geometry engineered to promote clean chip formation, reduce thrust, and improve surface finish on threaded features.
- Durable, Long-Lasting Performance: through-coolant design combined with carbide durability extends tool life in production environments, lowering downtime and replacement costs.
This tool is ideal for precision manufacturers, job shops, and engineers who require repeatable 6 × 1 thread profiles with efficient coolant delivery. Use it for threaded through-holes and blind-hole applications where chip evacuation and temperature control are critical to achieving tight tolerances and high-quality thread surfaces.
