12 1/4 Inches PDC Bits With 16mm Cutters And 5 Blades

Note :The upper limits of WOB and RPM in above table should not be used simultaneously.

1.The  PDC  bit is made entirely of medium carbon material. Holes are drilled on the working face of the drill bit, and the PDC cutting teeth are fastened to the drill bit crown by a press-fit method.

2.The drill bit crown is treated with a surface hardening process to enhance its erosion resistance.

3.Advantages and Disadvantages：

  Advantages：Simple manufacturing process

 Disadvantages：The drill bit body is not resistant to erosion, and the cutting teeth are difficult to secure.

Structure and Materials: PDC  drill bits adopt a steel body structure, mainly made of alloy steel, with high strength and toughness. The cutting teeth are usually polycrystalline diamond (PDC) composite cutters, which have high hardness and good wear resistance, and can effectively improve the service life and drilling efficiency of the drill bit.
