Custom Process
If you need to customize the product, please specify the requirements for customization before placing an order.
Please let me know the following informations.
Customized products
The main parts that can be customized are: PDC piece, hard alloy piece, thread type, bit gauge protection, size, type, coating, drawing.
1. Custom PDC
PDC comprise diamond surface, hard alloy as the base
D: Diameter, H: Height (The total height of the PDC), t: The Height Of Diamond Layer
The main sizes are: 1005,1304, 1305, 1308,1613,etc.
2. Custom Thread
If you need to customize the thread, please measure the data of each part according to the following diagram.
There are straight and conical threads. We can also send the thread drawings as shown below directly
3. Custom bit gauge protection
About drill bit steel body gauge protection teeth insets material and position.
(1) Material
Hard Alloy
Hard alloy is a powder of one or several refractory carbides (tungsten carbide, titanium carbide, etc.) as the main component, and a metal powder (cobalt, nickel, etc.) added as a agglomerant. The main models are YG, YW, YT. According to the features of the metal, according to the features of the formation, select the corresponding corrosion resistance, heat resistance, compressive strength of good materials. It has wide range of application, flexible choice according to the actual situation.
PDC
PDC is the abbreviation of polycrystalline diamond compact. A cutters to shear rock with a continuous scraping motion. The cemented carbide substrate and diamond surface, have good compressive strength, heat-resistant capacity, performance of cemented carbide and the hardness of diamond. It has good rock cutting performance.
(2) Position
Wing Side
Prevent excessive wear of the side of steel body in the drill work, and balance drilling process through the rock and soil fomation (choose more)
Under Wing
Bear part of the pressure brought by the side of drill bit during the bit rotation to increase the cutting speed and reduce blade wear
Top
Based on the same model increases the effective cutting area, thereby increasing the drilling speed
