YBC251 Coating Grade






 Carbide Substrate



  • Surface with Tin coating to reduce friction and easily identify worn out spot
  • Special structure Al2O3 layer forming a thermal barrier to protect insert from Anti-plastic deformation during high speed try cutting
  • TiCN layer has high wear resistance characteristic
  • Carbide substrate form by special crystal structure to increase the rigidness of the core base and thermal stability at high temperature

YBC251 consist of tenacious carbide substrate with strong cutting edge and optimal layers of MT-TiCN, thick layer of Al2O3, Tin Coating.  It's suitable for general purpose on wide range of material: finishing, semi-finishing and light roughing of steel, cast steel and stainless steel.
