42CrMo 20mm Shank Conical PCD Asphalt Road Milling Bits

PCD Asphalt Road Milling Bits Wirtgen Rehabilitations Conical Picks

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. According to the different road hardness with different bits.

The service life of PDC cutter is 30 times of the tungsten carbide cutter when used for milling asphalt concrete. The milling efficiency is 20% higher than tungsten carbide cutters. SWPCD/20 is cap-shaped carbide tip for removing asphalt layers, pick head without or with extractor groove as a dismantling aid. The shank diameter is 20mm, carbide tip diameter is 19mm x 10mm, high wear-resistant and strong breaking strength. Recommend for the large milling machines of Wirtgen, Dynapac, Cat, Kennametal or Sanvik.

 2. Specification

  3. Milling Bits Character 

• Taper-shaped cutters, the tip has strong impact and crushing force to the ground.

• Improve the wear resistance and maintain the sharpness by using PCD as the tip

• Reduce “Spall” because of the impact support from the thick tungsten carbide substrate

• Reduce the replacement of cutters effectively, shorten engineering period, reduce the milling cost and improve the milling quality

• Extremely destructive to the ground, smashing the ground and dig out the gravel, the speed is greatly improved than drilling by grinding

• The service life of PDC cutter is 30 times of the tungsten carbide cutter when used for milling asphalt concrete. The milling efficiency is 20% higher than tungsten carbide cutters

4. Milling Machines Type

SWPCD/20 can be used on compact and large milling machines.
