QL80 DTH Ballistic Button Bits Detailed Introduction and Price
QL80 DTH Spherical (Ballistic) Button Bits
1. Overview
QL80 DTH Spherical (Ballistic) Button Bits are specifically designed for pneumatic impact drilling (DTH) rigs. They are suitable for drilling operations in various hard rock and abrasive formations. The unique spherical (or ballistic, depending on the model) tooth setting design enhances the wear resistance and drilling efficiency of the drill bit.
2. Main Features
Strong Wear Resistance: Made of high-quality alloy steel material and subjected to special heat treatment, these bits offer improved wear resistance and service life.
High Drilling Efficiency: The spherical or ballistic toothed design effectively crushes rocks and increases drilling speed.
Strong Adaptability: Suitable for drilling into various hard rocks and abrasive formations, such as granite, marble, and basalt.
Easy to Replace: Designed with standard specifications, these bits are compatible with various DTH drilling machines, making them easy to replace and maintain.
3. Technical Parameters
Model: QL80
Diameter: Typically 203mm (8 inches), but specific dimensions may vary based on the manufacturer and application.
Gear Shape: Spherical or ballistic (tapered shape similar to a bullet or missile tip).
Drill Face Shape: Flat, concave, or convex, selected according to specific needs.
Work Pressure: Usually within the range of 8-30 bar, depending on the drilling rig and formation conditions.
Packaging: Wooden crates are used for packaging to ensure safe transportation.
4. Application Fields
QL80 DTH Spherical (Ballistic) Button Bits are widely used in mining, water well drilling, geological exploration, building foundation construction, and other fields. Their superior performance and wear resistance are particularly recognized in projects requiring drilling into hard rock and abrasive formations.
5. Supplier and Purchasing Suggestions
Multiple professional manufacturers, both domestically and internationally, produce QL80 DTH Spherical (Ballistic) Button Bits, such as Luoyang Shandike Mechanical Equipment Co., Ltd. in China. When purchasing, it is recommended to choose the appropriate model and specifications based on specific needs and budget. Additionally, select suppliers with a good reputation and after-sales service to ensure product quality and support.
6. Working Principle
During operation, the pressure regulating mechanism pushes the drill tool forward, keeping the drill bit in contact with the rock at the bottom of the hole. The DTH hammer at the front end of the drill rod, under the action of air pressure, continuously impacts the drill bit. The bit obtains impact energy and sinks into the bottom of the hole, generating an impact force that crushes the rock.
7. Popular Models
The most popular specifications include:
QL80-203mm/8’’, 819+1219
QL80-216mm/8 1/2’’, 1019+619+8*19
QL80-222mm/8 3/4’’, 1219+619+8*19
QL80-254mm/10’’, 1019+619+8*19
The exact bit size can vary depending on specific drilling requirements. The buttons can be spherical or ballistic, chosen based on the rock formation.
8. Function of Splines Designs
Processing strictly in accordance with design requirements to ensure proper clearance and uniformity of splines.
Carburizing and quenching of the surface to increase surface hardness and resistance to plastic deformation and impact fatigue.
Reducing surface roughness and improving contact accuracy.
Increasing the cross-sectional area of the splines to enhance the strength of the drill bit.
Summary
QL80 DTH Spherical (Ballistic) Button Bits are a high-performance and wear-resistant pneumatic impact drill bit suitable for various hard rock and abrasive formations. When selecting and using these bits, reasonable choices should be made based on specific needs and conditions. For faster penetration in softer rock formations, ballistic button bits may be preferred, while spherical button bits may be more suitable for harder rock or longer durability requirements.
