Description
The Carmex MTD Thread Mill is a precision carbide tool engineered to drill, chamfer, and thread mill in a single pass. Perfect for high‑volume production, it delivers fast cycles and consistently accurate internal threads for metric M10 x 1.5 applications. 
- Two-fluted design: Enables drilling, chamfering, and thread milling in one operation to reduce cycle times and eliminate extra tool changes.
- Thread size: Metric M10 x 1.5 for standard internal threading in common metals.
- Chamfer angle: 45° chamfering at entry for clean thread starts and improved engagement.
- Internal threading compatibility: Supports both right- and left-hand internal threads.
- Hole types: Effective for both blind and through holes with a single tool.
- Coolant and chip control: Internal coolant bore enhances cooling and chip evacuation for longer tool life.
- Carbide grade and coating: Optimised MT7 Sub-Micron carbide with a PVD triple coating delivers smooth cutting, high hardness, and robust performance.
- Thread quality: Produces high-quality internal threads with consistent pitch and surface finish.
By unifying drilling, chamfering, and threading into one pass, this tool minimizes setup complexity and boosts production throughput. The MT7 Sub-Micron carbide formulation combines hardness and toughness to withstand demanding cycles, while the internal coolant bore helps maintain thread accuracy and surface finish across both blind and through-hole applications. Designed for metric M10 x 1.5 threads, it’s a reliable choice for machine shops and contract manufacturers seeking repeatable, high-quality internal threading performance.
