UYNB

UYNB-2-Flute Long-Neck Micro Ball End Mill

Commodity Brief

Recommended for fine 3D contours in carbon, alloy and prehardened steels, including small features at greater reach or near adjacent walls.
The two-flute, 30°-helix design uses AlTiCrN coating. A short cutting section and reduced neck combine cutting reach with wall clearance, with multiple effective-length options at each diameter.
⌀0.1–0.9 mm; 86 sizes.
