MYNB

MYNB-2-Flute Long-Neck Micro Ball End Mill for Hardened Steel

Commodity Brief

Recommended for fine 3D finishing in prehardened and hardened steels, including small contours at greater reach or close to adjacent walls.
Two flutes, a 30° helix and TiSiN coating are paired with a short cutting section and reduced neck for wall clearance in extended-reach work. Each diameter offers multiple effective lengths.
⌀0.1–0.9 mm; 86 sizes.
