The Steel body PDC bit body is made of AISI 4145H round steel. The cost of Steel body PDC bit is lower than that of Matrix body PDC bit.

Every Steel body bit shall have heat treatment, to improve the mechanical properties of steel, to eliminate residual stress and improve the cutting performance. Each blade surface shall be welded with hardened material to increase wear resistance and erosion resistance.

Most of our raw material is made in the USA and France. Our supplier technical engineers come to our factory training our welder and have a meeting to show their new products regularly. We communicate with our supplier very well and are very happy. So if our customers need, we can ask our engineer to have a meeting with each other face to face. And Every bit has its own tracking card and serial number. For any of our bits shipment to the field, you can provide the serial number, then we will check what kind of cutters we use in the steel body PDC bit and what about the design. Then we can make an optimized design very fast.
