SRK3-PT Kennametal Concrete Grinder Teeth For Road Stabilization And Milling   1. Road Milling Bits Description  Road milling bits are also known as asphalt and concrete cutting bit, road planning picks, road milling machine cutter teeth, which are used as wear parts of road milling machine in road construction. Bit is installed in milling drum of milling machine and cut the road surface. The bits have two type, asphalt bits and concrete bits. Different bits are used on different aggregate and different milling machines.   Alloy steel Body, made by material ASTM4142 or 42CrMo,heat treatment with 40-44HRC hardness, has high toughness and wearable character. Tip with above 50 HRC hardness is made from low press sintered technology, reasonable proportion of tungsten cobalt alloy to ensure the wear resistance and fracture resistance of the cutting pick   SRK3-PT is cylindrical carbide tip for removing concrete, pick head without or with extractor groove as a dismantling aid.
