Product Description

YG-1 G9B81 K-2 is a TiAlN-coated solid carbide two-flute ball nose end mill for rib processing. It mills radius-bottom slots, fillets and special contours in detailed rib-processing applications. Its 30° helix geometry suits dry milling applications at high temperatures. Plain-shank variants cover 0.4–4 mm mill diameters with R0.2–R2.0 ball-nose radii. All listed variants have a 50 mm overall length for compact profiling operations. The ball-nose radius tolerance is ±0.02 mm for accurately defined profiles. The series is classified for ISO P, M and K material groups. Its compact diameter range supports machining narrow rib-processing features and detailed contours. Diameter and radius options suit small, detailed contour milling requirements.
