Carmex Thread Mills Carbide Drill Mill - Metric - M4 x 0.7 - UnCoated

The Carmex MTD Thread Mill is a carbide drill‑mill that handles drilling, chamfering, and thread milling in a single pass. It’s designed for metric M4 x 0.7 threads and high‑volume production, delivering precise results with minimal tool changes.

• Two‑fluted design: Combines drilling and threading in one operation for faster cycle times and streamlined setups.
• Metric size: M4 x 0.7 thread specification tailored for common miniaturized assembly applications.
• 45° chamfer: Provides a clean start and robust thread roots, reducing prep and finishing steps.
• Internal coolant bore: Directs coolant where it’s needed to control heat and evacuate chips during cutting.
• MT7 Sub‑Micron carbide with PVD triple coating: Optimised hardness and toughness with a smooth cutting surface for high performance and longer tool life.
• Internal thread compatibility: Fits both right‑ and left‑hand internal threads for versatile machining setups.
• Hole versatility: Effective for both blind and through holes without changing tools.
• Production efficiency: Reduces cycle times by combining multiple operations and eliminating unnecessary tool changes.

In practice, this thread mill helps shops boost throughput on CNC mills by eliminating separate drilling and tapping steps, while maintaining excellent thread surface quality. The internal coolant bore and advanced carbide grade support reliable performance across repetitive jobs, delivering consistent results in mass production environments. Whether you’re outfitting a high‑volume production line or refining a precision small‑lot process, the Carmex MTD Thread Mill offers a durable, efficient solution for metric M4 x 0.7 threads.
