• 4N‑E57 chipbreaker for stable chip control

Boosted throughput through advanced coating and grade

The combination of Tiger‑tec Silver coating and the WKP35S carbide grade delivers a measurable improvement in tool life and process consistency. Coated carbide reduces wear on cutting edges, enabling higher cutting speeds and longer continuous operation. For workshops and production lines this means fewer tool changes and lower per‑part machining costs; the enhanced wear resistance is particularly beneficial during extended drilling and counterboring cycles where heat and abrasion accelerate edge degradation.

Consistent chip control for safer, cleaner machining

The integrated 4N‑E57 chipbreaker is designed to produce predictable chip shapes and prevent entanglement during holemaking. Stable chip formation reduces vibration, protects the cutting edge and improves the surface finish of bore walls. For operators less familiar with chipbreaker functionality: the chipbreaker geometry modifies the cutting process to segment or curl chips, making them easier to evacuate and decreasing the risk of workpiece damage or tool jamming.

Production security and application scope explained

Belonging to the Tiger‑tec Silver series, the grade is a coated carbide solution geared towards ISO groups P and K, i.e. steel and cast iron according to ISO 513. This makes the insert a versatile choice for mixed‑material shops and series production where repeatability and predictable tool life are required. The design supports reliable repeatability in drilling and counterboring operations, helping to maintain cycle times and consistent part quality while lowering unscheduled downtime.
