44g Carbide W7 G20 Drill Machine Asphalt Milling Teeth

W7-G/20 Asphalt Pavement Bits Milling Drill Machine Cutter Teeth

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.

We use the highest grade tungsten carbide as raw material for tool tips. The crushed raw material dual grain structure tungsten carbide offers high abrasive resistance. The carbide raw material is pressed and sintered to produce high-quality dual grain structure tungsten carbide that has incredible welding properties plus high wear resistance.

SW7-G/20 is cap-shaped carbide tip for removing asphalt layers, pick head with extractor groove as a dismantling aid. The shank diameter is 20mm, carbide tip diameter is 21mm x 11mm, recommend for the 300-1000 HP large milling machines of , Dynapac, Cat, Kennametal and Sanvik.

4. Milling Bits Character

• Cost-effective asphalt blade, suitable for a large area of soft pavement milling;
• Professional welding process ensures high strength tungsten carbide steel knife tip and body connection;
• Tungsten carbide tip radian reasonable shape, the blade structure, improve the ability of broken asphalt;
• Various design can be applied to most of cutting conditions

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

W7-G/20 can be used on 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.
