1, rely on the drill bit substrate can rotate on the broken rock.
2, drill is to improve the cutting structure improvement of mechanical drill bit the most direct approach. Speed Cutting structure is mainly focused on the cutting teeth structure. Hard alloy tooth structure: wedge tooth, spoon, partial tooth shape top gear, such as the shape of wear tooth, and so on. In the recent ten years.
3, oil drilling and geological drilling applications in the most or disc bit. Disc bit rotates in has the impact and crushed and shear breakage strata rock, so, the role of the disc bit can adapt to the soft, hard, the various stratum in.
4, disc bit teeth type according to can be divided into milling gear (steel teeth), with disc bit teeth (with hard alloy with disc on disc bit teeth);
5, according to the number of disc can be divided into the single, double disc disc, three die and disc bit more.
