ST58 retrac mining rock bit
Product details
1.These threaded button bits can meet different drilling requirements in all rock formations.
We can also offer special designs according to the customer's requirements for specific work situation.
2.The button bits can transmit intensive impact energy into the rock with the least loss of energy.
3.We select high-strength structure alloy steel and carbide with best quality to ensure the drill body and alloy body can achieve uniform wear, thus the service life of bits will be increased.
Advantages:
1. A super long life. The grinding/consumption ratio of PDC is 20-40 times that of tungsten carbide bit and 10 times that of diamond bit.
2. No.45 steel as the drill bit body;
3. High drilling speed.
4. Advanced geometric design for faster penetration;
5. Over 40 years manufacturering experience;
6. Solid quality;

Bit Face Shape Selection
1.Drop Center Bit:For high penetration rates in soft to medium hard and fissured rock formatios 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 fIushing capacity
3.Convex Face:For hiigh penetration ratas m soft to medium-hard wlth low to medium air pressures It is the most rasistance to steel wash. and many reduce the load and wear on the gauge buttons. but poor hole deviation control.
4.Double Gauge Face:This kind face shape is suitable for fast penetration rates in medium to hard rock formations. Designed for high aii 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 appllications with high air pressure. Good penetration rates an resistance to steel wash.
carbide button shape selection
1.Domed /Round Buttons are usually used as gauge buttons of DTH Bits. suitable for very abrasive and very hard formations.
2.Parabolic Buttons are usually used as gauge buttons and front buttons of DTH Bits, suitable for medium abrasive and hard formations.
3.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.
4.Sharp Buttons are usually used as front buttons of DTH bits for soft formations where fast penetration rates are possible
5.Flat buttons are usually used as protection buttons to reduce Near on rubbing surfaces of DTH Bits.
