Features:
1. Short parabola, low tooth density, small elevation design, strong drill bit attack;
2. Long diameter preservation, shallow inner cone, and good directional ability of the drill bit;
3. Composite design of conical teeth in the rear row. The front teeth cut the formation, while the rear conical teeth crush the formation. By using a combination of crushing and cutting methods, the rock breaking power of the drill bit is effectively increased, greatly improving the mechanical drilling speed.
4. It can also be equipped with axe shaped teeth to improve grinding resistance and impact resistance, resulting in a longer lifespan of the drill bit.
Applicable strata:
1. Under the compaction of high mud density in deep wells, it is difficult for ordinary drill bits to penetrate and the machine speed is low,;
2. Simplifying the drilling tool assembly reduces the speed of the drill bit and reduces the mechanical drilling speed in formations with low drilling speed (such as Maokou);
3. Specially suitable for speed increase in hard formations such as the Longtan Formation, Maokou Formation, and Qixia Formation (without flint).
