The Carmex Spiral Mill Threading Insert for BSPT threads (H45-11BSPTMT7) is a versatile threading and milling solution designed for a wide range of applications—from precise small-part work on compact machining centers to demanding production milling on high-power machines. The spiral flute design enables smooth cutting at higher feed rates, helping to shorten cycle times and boost overall productivity.
Designed to work with spiral toolholders that hold 1 to 9 inserts in a compact cutting diameter, it features a unique clamping method that ensures optimal indexability. This practical setup reduces downtime and minimizes vibration and chatter, delivering reliable finishes across threading, roughing, and finishing passes.
- Fast, smooth cutting at high feed rates: The spiral geometry enables a smooth cutting operation at elevated feed rates, shortening machining times and increasing throughput.
- Compact, indexable insert system: Spiral fluted toolholders accommodate 1–9 inserts in a small cutting diameter with a unique clamping method that ensures optimal indexability and minimal downtime.
- MT7 TiN-coated inserts for broad material compatibility: Sub-Micron MT7 inserts with a Titanium Nitride multi-layer coating (ISO K10‑K20) provide wear resistance and reliable performance across all materials.
Together, this spiral mill-threading system helps you speed up production, maintain consistent thread quality, and extend tooling life. It supports efficient setups, reduces rework, and delivers dependable results across threading, roughing, and finishing operations, making it a reliable choice for both proactive maintenance and high-volume manufacturing.
