*0# *5# *5# *5# *9# *4# **3# **3# **3# High-strength diamond composite drill bit with concave three-wing drill bit, easy to use. The strong diamond composite drill bit produced by our factory can hit hardness above *0 Rock coal mine, reliable quality, smooth shape design, is your choice, and can be customized. The drill bit produced by our factory has won unanimous praise from customers!
Functions and features:
1. Long life of the drill bit: the main cutting teeth are diamond composite chips, and the service life is more than *0 times that of cemented carbide and 4 to 5 times that of ordinary diamond bits;
2. Drilling: The diamond exposure is large (almost all the composite polycrystalline layer is exposed), and the drill bit can always remain sharp, thus greatly improving the footage speed;
3. Low-pressure and low-speed drilling: the drill bit uses scraping and shearing to break the rock, and the weight of bit only needs to be about 1/3 of the bit of the same diameter diamond impregnated bit;
4. Good gauge keeping effect: Our compound drill bit can be embedded with diamond polycrystalline gauge inside and outside. It has strong performance and good gauge performance, which can make the cutting teeth efficiently used. 5. Wide range of use: Practice has proved that the drill bit is suitable for carbon. The drilling of acid rock, limestone, chalkstone, claystone, siltstone, sandstone and other soft and medium-hard (rock formations with drillability below 9), compared with ordinary drill bits, especially drilling 6 The *-level rock formation is particularly effective;
6. Because of the fast drilling speed and long life, the number of trips and trips is small, and the drilling cost is greatly reduced, which is superior.
