254mm Hard Rock Drag Bits For Water Well Drilling

Down The Hole Rock Water Well DTH Hammer Drill Bit

Product Description:

The PDC drill bits we offered are used to penetrate the degassing hole, drain hole, and grouting hole of coal mine, water canservancy, water well and hydropower, road construction, bridge and building ect.

Electroplated diamond bit is a kind of technology that uses electroplating technology to wrap diamond sand on the drill body. According to the different rock layers, different electroplating configurations produce different matrix hardness.
Generally, electroplated diamond bits are divided into three types: low degree, conventional and high.

Electroplated diamond bit is widely used in hard rock drilling.

According to the different rock hardness, the matrix hardness can be divided into: low degree 5 ° - 15 °, 10-15 °, conventional 15 ° - 20 °, 20 ° - 25 °, 25-30 °, height 30 ° - 35 °, 35 ° - 40 ° and above 40 ° respectively, which can adapt to different rock layers. Electroplated diamond bits are in stock all year round in regular sizes: Φ 28, 36, 46, 56, 59, 75, 91, 110, 130, 150, 171, 200, 220, 225, 245, 275, 325, and larger sizes can be customized by our company.

Product Advantage:
 

1. We choose the best PDC cutters with excellent wearability and impact toughness, make the working life of our PDC drill bits are much longer than the other’s,
 

2. We built our own factory of drill bits. All our goods pass through our rigid quality control before shipment .
 

3. We have rich experience in the field of large engineering projects such as dam construction, road and railway construction , We have our own construction team.

Wholesale supply 50 , 55, 65 ,75, 89 ,94 ,113 ,133 , 153 ,high strength diamond composite bit, concave three wing drill, easy to use, our factory production of strong diamond composite chip bit, can drill more than 10 hardness rock coal mine, reliable quality, smooth shape design, is your good choice, factory direct sales, can be customized processing. The drill bit produced by our factory has been highly praised by our customers!

Functions and features:

1. The service life of the bit is longer than that of cemented carbide and 4-5 times of that of ordinary diamond bit;
2. High drilling efficiency: the diamond outcrop is large (almost all the composite polycrystalline layers are exposed), and the bit can always keep sharp, thus greatly improving the footage speed;
3. It can drill with low pressure and low rotation speed: the bit breaks the rock by scraping and shearing, and its WOB only needs about 1 / 3 of that of the impregnated diamond bit of the same diameter;
4. Good diameter protection effect: diamond polycrystalline can be inlaid inside and outside of the drill bit of our factory, which has strong wear resistance and good diameter maintenance performance, It has been proved that the bit is suitable for drilling soft and medium hard strata (with drillability below grade 9) such as carbonate rock, limestone, Cretaceous, clay rock, siltstone, sandstone and so on. Compared with the general bit, especially in the 6-9 rock stratum, the effect is particularly remarkable;
6. Because of its high penetration rate and long service life, the number of trips and trips is less, the drilling cost is greatly reduced, and the performance price ratio is superior.
