Chrome is the New Black


Gain the Ultimate Edge in Steel Turning

Engineered with speed, balance and versatility in mind, our new TP2501, TP1501 and TP0501 turning insert grades for cutting steel are the first to feature next-generation Duratomic technology, making them the most reliable, predictable and productive of their kind.

Plus, a thin chrome-colored layer coats these inserts, making used-edge detection possible with the naked eye – all without impacting tool performance or cutting data. As a result, you can process more parts per edge, limit production interruptions and reduce waste.
