PDC Reamer

　　After evaluating the actual field performance of the first-generation PDC reamer, our company's engineers designed an improved PDC reamer, which has the following features:

　　Several PDC compact inserts have been mounted on the edges of the reamer blades, similar to the back-reaming cutters of a PDC bit. These compact inserts can effectively protect the reamer body during use. They can also more effectively remove excess cuttings adhering to the borehole wall.

　　It can more easily remove key seats and more effectively enlarge the borehole in undergauge hole sections.

　　The flow area and flow pattern of the junk slots have been optimized, making it easier to discharge cuttings.
