Product Description

YG-1 K-2 G9444 solid carbide two-flute short-length end mill has a flat shank and TiAlN coating. It is designed for slotting and suitable for dry milling applications at high temperatures. Each tool uses a 30° helix, as specified for the G9444 short-length series. The two-flute geometry is specified for practical groove and slot milling tasks. The series is recommended across selected ISO P, M and K material groups. Nominal mill diameters run from 2 to 20 mm within this product family. The flat-shank configuration distinguishes G9444 from the related plain-shank K-2 series. Choose the diameter that suits the required slot width and machining program.
