UYB-2-Flute Micro Ball End Mill
Commodity Brief
Recommended for fine contours and radii in carbon, alloy and prehardened steels, particularly small features on miniature parts.
The two-flute, 30°-helix design combines AlTiCrN coating with a 2×D length of cut. Its ball-nose profile suits continuous curved surfaces and small blended internal radii.
⌀0.1–0.9 mm; 10 sizes.
