NNH-4RSP 4 flute high speed deep groove round nose end mills are available in a variety of sizes, from 1mm to 4mm in diameter, with a variety of lengths and cutting edge combinations. This allows users to freely choose the most suitable model according to the processing depth, surface shape and precision requirements, thereby improving flexibility and efficiency.
Compared with traditional flat-bottom or standard round nose end mills, the deep groove round nose design provides a smoother transition. This feature helps reduce cutting resistance and improve stability, making it particularly suitable for precision surface processing such as mold cavities and high-speed engraving.
NNH-4RSP adopts high-performance AlTiSiN coating with excellent heat and oxidation resistance. This enables the tool to maintain a sharp cutting edge even under high-speed and high-temperature conditions, thereby reducing tool wear. The ultra-fine particle (0.4μm) substrate combined with a 30° helix angle ensures smooth chip evacuation, further improving processing efficiency and ensuring reliability when processing high-hardness workpieces.
This series of end mills is suitable for a variety of materials, including carbon steel, alloy steel, pre-hardened steel (35–45HRC), heat-treated steel (45–55HRC), and stainless steel (≤30HRC). It can also be effectively used for copper alloys and other non-ferrous metals. Especially in high-speed and high-hardness machining applications, NNH-4RSP exhibits excellent wear resistance and stability.
