Product Description

YG-1 GM902 X-Power Pro is a solid carbide, two-flute ball nose end mill with taper neck. The taper neck provides extended projection for high-efficiency milling in deep slots and recessed areas. Y coating supports milling carbon, alloy, prehardened and hardened steels up to 55 HRC. The ball nose profile suits contoured work requiring a controlled R0.5 to R4.0 cutting radius.

Selected GM902 variants use 1°30′ taper necks, while larger listed sizes have 3° taper necks. Plain shanks range from 6 to 10 mm, supporting secure conventional toolholding. Use these cutters for precision mould and die machining, alongside general machine-part applications.

  • Solid carbide construction with Y coating
  • Two-flute ball nose geometry for contoured milling
  • Taper neck supports extended reach into recessed features
  • R0.5 to R4.0 ball nose radius range
  • Suitable for steels hardened up to 55 HRC
  • Plain shanks from 6 to 10 mm
