what is a button type drill bit?
A button type drill bit is a crucial tool in rock drilling, especially in top hammer and DTH (Down-The-Hole) drilling applications. Its distinguishing feature is the presence of hard, wear-resistant carbide “buttons” (inserts) strategically hot-mounted into the bit’s steel body.
These buttons, typically made from tungsten carbide, are the primary cutting elements. As the bit rotates and receives percussive energy, these buttons impact and crush the rock, efficiently breaking it into smaller fragments.
The design, including the shape and arrangement of these buttons, as well as the overall face design of the bit, is optimized for various rock hardness levels and drilling conditions, ensuring efficient penetration, long service life, and cost-effectiveness.
Button Bit Insert Types
Button bit inserts are the core of a drill bit’s cutting efficiency, designed with various shapes to optimize performance across diverse rock formations and drilling conditions.
Each insert type is engineered to interact with the rock in a specific way, influencing penetration rate, bit life, and overall drilling economy. Understanding these variations is key to selecting the right bit for your project.
Spherical Button This universal button type offers good wearing resistance, making it best suited for hard ground conditions with rock strengths typically ranging from 27,000 to 48,000 PSI (180 to 320 MPa). It performs well in abrasive to very abrasive ground types, providing durability and consistent performance in challenging formations.
Hemispherical Button Similar to the spherical button, the hemispherical button is also a universal type known for its good wearing resistance. It is highly effective in hard ground, particularly in conditions with rock strengths of 27,000 to 48,000 PSI (180 to 320 MPa). This button is suitable for abrasive to very abrasive ground.
Parabolic Button Designed for fast penetration, the parabolic button is best suited for medium to hard rock formations with strengths between 15,000 and 25,000 PSI (100 to 170 MPa). It performs optimally in mildly abrasive ground, offering a balance between penetration speed and resistance to wear.
Conical Button This button type is designed for fast penetration and is best suited for smaller diameter bits. It is effective across all non-abrasive ground types, making it a versatile choice for situations where high penetration rates are desired without significant abrasive wear.
Ballistic Button The ballistic button is characterized by its very fast penetration capabilities, making it ideal for soft rock formations with strengths ranging from 10,000 to 20,000 PSI (70 to 140 MPa). This type of button performs exceptionally well in non-abrasive ground, maximizing drilling speed in softer conditions.
where to use button type drill bits?
Button type drill bits are highly versatile and widely used across various industries that involve rock excavation and drilling. Their robust design and ability to perform in a range of rock hardnesses make them a go-to choice for numerous applications.
Mining: Essential for both underground and surface mining operations, including blast hole drilling for ore extraction and development work in various rock types.
Tunneling: Critical for creating boreholes for blasting in tunnel construction for roads, railways, and utilities, especially where ground conditions can vary.
Quarrying: Frequently used in quarries for drilling blast holes to break down rock for aggregate, dimension stone, or other mineral products.
Construction: Employed in general construction for foundation drilling, excavation for infrastructure projects (like roads, bridges, and pipelines), and site preparation.
Hydropower Projects: Utilized in the construction of dams and hydroelectric power plants, which often involve extensive rock drilling in diverse geological settings.
Geotechnical Engineering: Used for site investigation, soil sampling, and ground stabilization, providing crucial data on subsurface conditions.
Water Well Drilling: Applied in drilling wells to access underground water resources, demonstrating their effectiveness in different ground formations.
how to use button type drill bits?
Using button-type drill bits effectively involves proper setup and operational techniques to maximize their performance and lifespan. The button bits are attached to drill rods, which are then connected to a rock drill or rig.
During operation, percussive energy from the drill is transmitted through the rod to the bit, while rotational force grinds the rock. Consistent flushing with air or water is crucial to clear cuttings and cool the bit.
Proper Bit Selection: Choose the correct button shape, face design, and diameter based on the rock type, hardness, abrasiveness, and desired hole straightness.
Correct Drilling Parameters: Adhere to recommended feed pressure (thrust), rotation speed, and impact frequency for the specific bit and rock conditions to optimize penetration and minimize wear.
Adequate Flushing: Ensure a continuous and sufficient flow of flushing medium (air or water) through the drill string to remove rock cuttings from the borehole and cool the bit’s carbide inserts, preventing premature wear and bit jamming.
Bit Sharpening/Grinding: Regularly inspect the buttons for wear. When the carbide buttons show signs of excessive wear (e.g., flattened or dulled), they should be reground to their original shape to maintain optimal penetration rates and extend bit life.
Maintain Drill Rig: Ensure the drill rig, drill rods, and shank adapters are in good condition and properly aligned to prevent premature bit failure and ensure efficient energy transfer.
