Construction machinery accessories Rotary drilling rig accessories drill barrel
Introduction
In engineering, there are often hard bedrocks, large flow stone layers and hard permafrost layers.
It is difficult to drill directly with a mud rotary drill bit. It is necessary to cut the ring groove with a core barrel first, and then drill a hole with a rotary drill bit.
It can greatly increase the drilling speed. The cutting teeth can be bullet teeth or cones. Core barrels with bullet teeth are used in soft formations and permafrost. Core barrels with cones are used in hard formations.
Features
Drill and grind the drill bit together to cut the ring together. For hard rock, low noise and high efficiency. The cone is detachable and easy to replace. High-strength alloy blocks are evenly distributed on the top, and evenly cut and drilled by the rotation of the roller itself. The wear-resistant strip discharges the rock powder in the cutting area to the top smoothly through an inclined angle to reduce cutting resistance. Various specifications of drill bits can be manufactured according to the parameters provided by the customer.
