Tangential cutters, AWR©

production of mining tools
Working part of the AWR© cutters is covered with wear-resistant tungsten-carbide coating applied through plasma transferred arc welding.

Building-up of the working part of the AWR© cutter ensures:

  • additional wear protection of the cutter;
  • arcing reduction in case of contact with rocks.


Wear-resistant plasma transferred arc welding:

  • Chemical composition of coating: NiCrBSi + tungsten carbides
  • Matrix hardness: 54 HRC
  • Carbides hardness: > 1700 HV0.03
  • Carbides content: 60%
