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.


SRK1-PT is cylindrical carbide tip for removing concrete, pick head with extractor groove as a dismantling aid. The shank diameter is 20mm, carbide tip diameter is 10mm, recommend for the medium compact machines of Wirtgen, Dynapac, Cat, Kennametal and Sanvik.

4. Carbide Milling Tips Character

  • Be used for road milling, ground stabilizing, cutting asphalt and concrete
  • the material of tooth body is 40CrMo or better, the machining process is forged
  • various design can be applied to most of cutting conditions
  • Speedy creation of samples and prototypes
  • High purity carbide tips are used for great strength
  • Consistently high, pore-free tungsten carbide quality produced through an exact process resulting from years of experience
  • Production equipment and processes specially developed to the utmost degree of perfection by experts in combining tungsten carbide and steel


5. Carbide Picks Structure

  1. Optimised carbide distribution, 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. Solid steel body geometry, 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. Reinforced wear plate with improved shape, 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


SRK1-PT series milling bits widely used on Wirtgen small milling machines as well as the compact milling machines, such as the W35DC, W35Ri, W50, W50H, W55H, W50DC, W50R, W60R, W60, W100, W100R, W130H, W100F, W120F, W130F, W100CF, W120CF, W130CF, W150, W150CF.
