New Product Launch | PB2 Chip Breaker: Positive Insert for Semi-Finishing to Finishing Turning Operations

Common chip breakers currently on the market are plagued by issues such as high cutting force, insufficient chip pocket space and machining chatter. To address these pain points, ACHTECK Tools launches the new PB2 chip breaker. It covers a wide depth of cut range and delivers excellent chip breaking performance, enabling light cutting action for both external turning and internal boring. The new product further enriches the company’s turning tool portfolio for the small parts industry and helps reduce customers’ procurement costs.

Key Features of PB2 Chip Breaker

The curved cutting edge design effectively reduces cutting resistance. The elongated chip breaker land expands the chip pocket space for smooth chip evacuation, while the deepened chip groove at the cutting edge nose improves chip breaking capability under light cutting parameters.

Cutting Force Test Comparison

◾Cutting conditions：

DCMT 11T304E，4340#，Vc=220m/min，dry cutting

Compatible Grades

◾General-purpose turning grades, suitable for machining steel and stainless steel, with excellent wear resistance and chipping resistance.

◾Adopting ultrafine grain technology combined with nanostructured coating technology, the dense structure significantly improves wear resistance and built-up edge (BUE) resistance.

Machining Cases

Going forward, we will launch more specialized cutting tools with higher efficiency, higher precision and higher reliability to meet the strict requirements of machining customers for machining accuracy, efficiency, environmental protection and energy conservation. Stay tuned for more updates.
