4 Flute Deep Groove End Mills for Graphite Machining

The NNS-4TP 4 Flute Deep Groove End Mills for Graphite Machining are purpose-built for high-precision graphite applications. They feature a uniquely engineered deep-groove geometry and four flutes, ensuring smooth chip evacuation and significantly reduced cutting resistance. This design takes into account the brittle nature and dust characteristics of graphite, allowing for more efficient and stable machining.

In terms of manufacturing processes, we use a diamond coating combined with advanced coating techniques to achieve excellent adhesion on the tool surface, enabling outstanding wear resistance even in high-temperature environments. Meanwhile, our precision grinding method ensures superb coaxiality over an extra-long effective cutting length, delivering crisp and precise results in deep-cavity machining.

Specializing in graphite material requirements, these end mills easily handle common carbon graphite grades such as G-20 and G-30, particularly excelling in graphite electrode production and deep-groove milling scenarios. Their consistent performance makes them a strong contender for demanding, high-intensity manufacturing tasks.

Notably, the NNS-4TP range spans diameters from 0.5 mm to 4.0 mm, with flexible flute and length combinations to accommodate various depth and accuracy needs. Whether you’re tackling micro-scale features or large deep-groove cutting, you’ll find a sub-model perfectly tailored to elevate both efficiency and quality in your graphite machining.
