Reverse Circulation Drill Bit
The reverse circulation drill bit is used in combination with the reverse circulation impactor and is driven by high-pressure air to obtain large rock samples from the central discharge hole. The reverse circulation drill bit is made of high-quality alloy and alloy steel matrix, with long service life. Under the condition of not requiring a complete core, the working speed is greatly improved and the cost is reduced compared with the original drilling rig. Our company provides process design and drill bit customization. Please refer to the detailed parameter table of the reverse circulation drill.
