We manufacture kinds of coal PDC bits for directional drilling, used in soft to medium seams. Varies cutters and designs are deployed to yield maximum penetration rate, in-hole stability and long life depending on different applications. The maximum bore hole we get have achieved 203mm in diameter.
Our PDC bits are made by:
1 Premium grade alloy steel body
2 Multi-blade to provide balance and in-hole stability
3 Compact profile design
To provide below values:
1 Drill faster and other excellent drilling performance
2 Reduce operation cost as a result of more production per shift
We provide matrix body PDC bits, steel body PDC bits and reamers as below.
Enhanced three blade/four blade bits are developed to fulfill drill seam hardness until 8 grade (Protodikonov Hardness) in directional drilling. Conventional size
our clients required are Ф96mm, Ф98mm and Φ120mm. More requirements from clients are also expected.
