  1. Tungsten Carbide

  2. What is Tungsten Carbide ? • A Ceramic • Tungsten is a Refractory Metal with the highest melting temp. at 3410°C • The Knoop hardness is around 2100 • The mixture of the two reduces cost for tools.

  3. How it is dressed to the tool • Mill or shoe is heated to where the pores of the iron open • Then the brazing alloy made of copper and a high nickel content is melted down and bonded into the iron’s pores. • This bonds the tungsten carbide to the mill

  4. What is it used for? • For downhole cutting and milling • The removal of loose junk such as bit cones, packers, tong dies, and cement. • The abrasive surface of the mills from the tungsten-carbide is what does the cutting. • When cutting is done, the object that was being cut is now small shavings that can be circulated out.
