Carmex Spiral Mill Threading Insert - Unified - H17I12UNMT7

The Carmex Spiral Mill Threading Insert – Unified – H17I12UNMT7 is a spiral-fluted threading and milling insert system built for versatile industrial use. It delivers smooth cutting at high feed rates to shorten machining times, making it a practical choice for both small components on compact centers and heavy-duty milling on high-power machines.

Its spiral toolholder design supports 1 to 9 inserts in a compact cutting diameter, enabling flexible setups for threading and milling tasks. A unique clamping method ensures optimal indexability, while reducing vibration and chatter for clean cuts and consistent finishes across threading, roughing, and finishing. Inserts are MT7 Sub‑Micron Grade with a TiN multi-layer coating (ISO K10–K20), a general-purpose option engineered to perform reliably on a wide range of materials.

• Efficient Spiral Cutting: The spiral flute design enables smooth cutting at high feed rates, reducing machining time and boosting productivity across a wide range of components.
• Flexible 1–9 Insert Toolholder: Holds 1 to 9 inserts in a compact diameter, allowing quick adaptation to varying part sizes and machining tasks.
• Indexing Reliability with TiN-coated MT7 Inserts: The unique clamp ensures precise, repeatable indexing, while MT7 Sub-Micron Grade inserts with TiN coating provide durable wear resistance across materials (ISO K10–K20).

Together, the Carmex Spiral Mill Threading Insert system delivers durable performance, smoother finishes, and longer tool life. You’ll experience faster part cycles, fewer interruptions for tool changes, and more predictable results across threading and milling passes, making it a trustworthy choice for engineers, machinists, and shop floors aiming for higher productivity on a broad material set.
