China Cheap price Milling Bit - IS09001 W8 20mm Round Shank Kennametal Cutting Tips -Sinodiam

W8 Asphalt Road Construction Tungsten Carbide Tipped 20mm Round Shank

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.

4. Carbide Milling Tips Characters

• Be used for road milling, ground stabilizing, cutting asphalt and concrete
• Various design can be applied to most of cutting conditions
• High purity carbide tips are used for great strength
• 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. 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.
