"T tooth" drill is our scientific and technical coil tubing drilling rig personnel to develop new products first domestic. Its features are as follows:
After a drill before using lip surface is flat, use a back order, lip surface is formed concentric teeth (grooved).
2, a conventional concentric concentric tooth tooth bit once polished, then lost the advantage and ordinary flat teeth as concentric drill performance. But "T tooth" wear diamond drill along with the active layer can be gradually deepened tooth concentric grooves, until the work is completed wear layer, and always maintain the advantages of concentric teeth.
3, the drill can be formed concentric teeth, broken rocks ahead, forming a plurality of free surface, both the drill roller reamers drilling grinding and crushing, vibration broken rock, resulting in relatively coarse-grained rock powder, greatly improve the drilling efficiency. According to several experiments situation showed an increase of about 100 percent over the same drill, especially for hard drilling slipping formation.
4, can reduce the radial drill swing, improve drilling stability, oriented to prevent hole inclination, to reduce the impact of the diamond, enhancing penetration ability.
