Application of Cemented Carbide Rods Blank
1. For making carbide mold punches
2. For making carbide core pins
3. For making carbide dental burrs
4. For making carbide PCB drills, drills, end mills & hole drilling tools, boring bar
5. For making carbide reamers
Carbide round bars have superior hardness, flexural strength, concentricity and straightness.
The round bar is press molded by molding and extrusion.
The cemented carbide round bar is sintered by a vacuum integrated furnace or a high-pressure sintering furnace, and has high overall performance and no porosity.
The carbide rods are used for cutting aluminum alloy, cast iron, stainless steel, Refractory alloy steel, nickel-based alloy, titanium alloy and nonferrous materials, For making PCB drills, drills, end mills &reamers, mold punches ,core pins & hole drilling tools, etc.
