NNC-2BS 2 Flute Micro Diameter Ball Nose End Mills provides a variety of tool diameter and blade length combinations to meet different precision machining needs. The tool diameter ranges from 0.1mm to 0.9mm, and the R angle ranges from 0.05 to 0.45. With different blade length designs, such as 0.1mm, 0.3mm, 0.7mm, etc., it can flexibly adapt to micro-machining scenarios. The total length of all tools is 50mm, and the shank diameter is unified to 4mm, which is convenient for standardized clamping and improves machining consistency.

This series of milling cutters adopts a micro-diameter ball head structure, which can achieve high-precision 3D contour processing in a very small area, and is suitable for engraving complex shapes such as curved surfaces and precision grooves. The 30° helix angle design enhances cutting smoothness, helps reduce cutting resistance, improves surface finish, reduces tool wear, and extends service life.

The milling cutter adopts high-precision grinding technology, combined with advanced chromium-aluminum composite coating technology, to make it have higher wear resistance and oxidation resistance. In addition, the (0.4μm) ultrafine particle substrate ensures the edge strength, ensures the tool stability during processing, reduces the risk of tool breakage, and thus improves the overall processing efficiency.

The NNC-2BS 2 flute micro diameter ball nose end mills series is suitable for processing a variety of materials, including soft steel (≤22HRC), alloy steel (25-35HRC), pre-hardened steel (35-45HRC) and some stainless steel (≤30HRC). At the same time, this series of tools performs well in the processing of copper and copper alloy materials, and can meet the needs of high-precision industries such as precision molds, electronic parts and medical devices.
