Description
The Carmex Carbide Mini Thread Mill is a compact, high‑performance threading tool designed for metric threads in internal and external applications. It’s ideal for machinists who need precise, fast threading in deep holes across a range of materials, including hardened steels.
- Thread sizes: Metric thread options M8 x 1.25, M10 x 1.25, and M12 x 1.25—all achievable with a single tool.
- Coating & grade: MT7 sub‑micron carbide with a TiAlN multi‑layer coating (ISO K10‑K20) for exceptional wear resistance at high speeds.
- Through‑coolant: Coolant through the flutes provides efficient cooling and chip evacuation, especially in deep holes.
- Flute design: Spiral flutes deliver smooth cutting action; 3–5 flutes reduce machining time and enhance rigidity.
- Depth capability: Optimized for deep‑hole threading, enabling long reach without compromising stability.
- Material compatibility: General‑purpose threading for all materials, with proven performance on hardened workpieces up to 45 HRc.
- Durability: Special triple coating and multi‑layer TiAlN protection extend tool life in demanding conditions.
- Versatility: A single tool can produce a wide range of threads and pitches, simplifying setups and reducing tool inventory.
Using this thread mill translates to shorter cycle times and fewer tool changes, thanks to its short profile and high‑speed capability. The through‑coolant system minimizes heat and improves surface finish, while the MT7 carbide core provides dependable performance across materials, including hardened steels. Whether threading small fasteners or precise bored holes, this tool delivers consistent thread quality, reduced risk of broken taps, and longer tool life.
