Bit face shape selection:
1. Drop Center Bit
For high penetration rates in soft to medium hard and fissured rock
formations. Low to medium air pressures. Maximum hole deviation
control.
2. Concave Face
The all-round application bit face specifically for medium hard and
homogenerous rock formations. Good hole deviation control and good
flushing capacity.
3. Convex Face
For high penetration rates in soft to medium-hard with low to
medium air pressures. It is the most resistance to steel wash, and
may reduce the load and wear on the gauge buttons, but poor hole
deviation control.
4. Double Gauge Face
This kind of face shape is suitable for fast penetration rates in
medium to hard rock formations. Designed for high air pressures and
good resistance to steel wash step gauge bit.
5. Flat Face Bit
This kind of face shape is suitable for hard to very hard and
abrasive rock formations in applications with high air pressures.
Good penetration rates an resistance to steel wash.
| Caibide BUtton Shapge | Domed / Spherical Button Domed / Spherical Buttons are usually used as gauge buttons of DTH Bits, suitable for very abrasive and very hard formations. | |
Parabolic / Semi - Ballistic Buttons Parabolic Buttons are usually used as gauge buttons and front buttons of DTH Bits, suitable for medium abrasive and hard formations. | ||
Ballistic Button Ballistic Buttons are usually used as front buttons of DTH BIts, suitable for medium abrasive and medium hard formations. They can also be used as gauge buttons if the rock is soft. | ||
Sharp Button Sharp BUttons are usually used as front buttons of DTH bits for soft formations where fast penetration rates are possible and button breakage is minimal. | ||
Flat Button Flat buttons are usually used as protection buttons to reduce wear on rubbing surfaces of DTH bits. |
FAQ
1.The Quality of Drill bit?
We have many series of rock bits,quality grades are different,and prices are different.We believe,the proper tools with higher cost-performance isthe most impormant.
3.How to send inquiry?
It is better send us detailed specificaltions of products,it is better attaching some photos for better understanding.If you are not experienced on drilling fields,for example,many customers don't know IADC code,please feel free,jusst tell us the applications like oil/gas/geothermal/HDD/ware/mining,depth of well,average hardness of rocks,then we will advise suggestions and solutions.
