| Detail information of PDC concave drill bits |
 This is the tungsten carbide blanks gauge, the material is cemented carbide, it is high hardness, wear resistance, and good toughness. Under the 500 degree remain the same, also under 1000 degrees as the very high hardness. so it is good choose for hard formation, you can reduce your cost. |
 This is the side water hole, there are three water holes, they can cool the PDC cutter and washout the head mud stone.To reduce off the field. |
 This is PDC concave drill bits two pillar, and the material is 1304 PDC cutter and cemented carbide, and there are two middle water hole, its function is cool PDC cutter and blow the mud stone.Prevent damage to the compact(PDC cutter). |
 This is concave drill bit PDC cutters. Material is diamond and tungsten carbide,so it is apply for hard rock ,1308 PDC cutter the mainly feature is high durability. |
| Application of PDC concave bits |
 Combining wear-resistance of PDC cutter and toughness of carbon steel makes the drill bit has a long service life and high drilling speed. PDC concave bit is suitable for drilling soft to medium hard rock formation. They are often use with underground drilling rig. Concave 3 wing drill bit is also a concave drag bit. 50 56 60 65 concave 3 wing drag bit has a higher durability. It is always the first choice of hole drilling. |
| PDC concave drag bits apply for rock formations |
 3 wing concave drill bits apply for soft(coal, clay, mudstone) and medium hard rock formation(sandstone, Limestone, marble). and 4 wing concave drill bit is also suitable for hard rock formations, such as flint, quartzite granite. |
