SP1480 bit is a double-tooth concave high-pressure down-the-hole drill bit, mainly used for geological exploration, water conservancy and hydropower, railway, bridge construction and other work.
Application of SP1480 down-the-hole impactor
SP1480 DTH drill bit features advantages
Long bit life
This drill bit is relatively wear-resistant in the actual working process. Because the wear ratio of the drill bit’s cemented carbide is more than 10-20 times that of similar products, the service life of the bit has been greatly extended.
Wide range of use
Practice has proved that the bit is suitable for drilling in medium-hard formations such as carbonate rock, limestone, chalk rock, clay rock, siltstone, and sandstone.
High drilling efficiency
This drill bit has high hardness and wear resistance, and the drill bit can always remain sharp, which greatly improves the gear feed speed. While the drill speed is high, the user experience is good, which improves user satisfaction.
Cost-effective
Because this drill bit has a fast drilling speed and long life, the number of drilling times is small, the drilling cost is greatly reduced, and it has an excellent cost performance. It is a good choice.
SP1480 bit technical parameters
SP1480 drill product introduction
The SP1480 down-the-hole impactor is connected to the drilling bit for drilling engineering. SP1480 uses high-quality steel and best-level alloy steel as raw materials, special heat treatment technology and advanced cemented carbide inserting technology, so that the drill bit can perform well even on hard rock formations, while saving energy.
This type of drill has a wide range of applications. Compared with ordinary drills, especially for drilling into 6-8 rock formations, the effect is particularly significant.
Alloy tooth profile selection
- Button
Application: DTH drill bit side teeth, suitable for abrasive and very hard rock.
- Parabolic tooth
Application: The side teeth and middle teeth of the down-the-hole drill bit are suitable for medium abrasive and relatively hard rocks.
- Bullet teeth
Application: The middle tooth of the down-the-hole drill bit is suitable for rocks with medium abrasiveness and medium hardness. Edge teeth can also be used when the rock is relatively soft.
- Sharp teeth
Application: The middle tooth of the down-the-hole drill bit is suitable for soft rock formations with high drilling speed and low tooth fracture.
- Flat tooth
Application: Protect the teeth of the side of the down-the-hole drill bit to reduce the wear on the surface of the bit body.
