matrix body

"matrix" is a very hard,rather brittle composite material comprising tungsten carbide grains

metallurgically bonded with a softer,tougher,metallic binder.matrix is desirable as a bit material,

because its hardness is resistant to abrasion and erosion.It is capable of withstanding relatively

high compressive loads,but,compared with steel,has low resistance to impact loading.

steel body

"steel" is metallurgically opposite of matrix,It is capable of withstanding high impact loads,

but is relatively soft, and without protective features would quickly fail by abrasion and erosion.

quality steels are essentially homogeneous with structural limits that raely surprise their users.

We had very good relationship with the PDC Cutter factory in the world ,Like USS ,E6,Smith ;

And discuss the cutter technology and long term cooperation and relationship. So that we can

improve our PDC drill bits performance , drilling faster and lower cost.
