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 aggragate 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, carbide tip size and grade will be different to make sure a better milling performance and life.
SW8/20 is cap-shaped carbide tip for removing asphalt layers, The shank diameter is 20mm, carbide tip diameter is 22mm x 12mm, high wear-resistant and strong breaking strength. Recommend for the large milling machines of Wirtgen, Dynapac, Cat, Kennametal or Sanvik.

5. Carbide Picks Structure
1. Reasonable proportion of tungsten cobalt alloy to ensure the wear resistance and fracture resistance of the cutting pick.
2. Excellent flow solder to ensure weld strength.
3. Unique design of the body to improve the efficiency of retraction, to ensure smooth rotation, new heat treatment process to guarantee the wear resistance and fracture resistance of the cutter shank.
4. Thicken gasket design, ensure long life of the toolholder.
5. Thickening the sleeve, ensure moderate tension and clamping force, easy installation and removal.
6. Milling Machines Type
W8/20 can be used on Wirtgen large milling machines, such as the W1500, W1900, W195, W2000, W200, W200F, W207FI, W205, W200H, W215, W20H, W215, W210XP, W2100, W220, W2200, W250, W240CR, W380CR.
