Product Description

YG-1 GM8A1 X-Power Pro is a Y-coated solid carbide two-flute corner radius end mill for rib processing. Designed for narrow rib features, its reduced neck profile provides clearance below the shank. This plain-shank range combines 1–6 mm cutting diameters with 0.1–0.5 mm corner radii. Length below shank spans 6–40 mm, supporting selection for varying rib depths and reach. Two cutting flutes and corner-radius geometry suit precision milling of rib profiles. Each tool uses a 4 mm or 6 mm shank according to mill diameter. It provides 1.5–9 mm length of cut across the specified GM8A1 family. Overall lengths from 45 to 100 mm complement the available neck reach.

  • Two-flute corner radius geometry for rib processing
  • Plain shank with reduced neck profile
  • 1–6 mm mill diameter range
