Accurate threading and a secure fit are essential for preventing bit loss and maximizing drilling efficiency and safety.
what are button bits?
Button bits are rock drilling tools that consist of a steel body embedded with durable tungsten carbide buttons.
These buttons are the cutting elements that directly impact and fracture the rock as the drill rotates and applies pressure. The strategic arrangement and design of these carbide inserts are crucial for efficient rock removal and the overall performance and lifespan of the bit.
Button bits are widely used in mining, quarrying, construction, and water well drilling for their ability to penetrate hard and abrasive rock formations effectively and offer superior wear resistance compared to traditional drill bits
why use button bits for rock drilling?
Button bits are the preferred choice for rock drilling due to their superior performance and cost-effectiveness compared to other drilling methods.
Their design, featuring robust tungsten carbide buttons embedded in a steel body, offers significant advantages in demanding rock drilling applications.
Here are the key reasons why button bits are used for rock drilling:
- Exceptional Hardness and Durability: Tungsten carbide is an incredibly hard and wear-resistant material, allowing button bits to effectively penetrate even the toughest rock formations while maintaining their sharpness for longer periods.
- Efficient Rock Fracturing: The strategic placement and design of the carbide buttons concentrate impact energy, leading to more efficient rock breaking and faster penetration rates.
- Extended Bit Lifespan: Due to the durability of tungsten carbide, button bits last significantly longer than traditional steel bits, reducing the frequency of replacements and minimizing downtime.
- Versatility in Various Rock Types: Different button shapes and configurations are available to optimize performance in a wide range of rock conditions, from soft to extremely hard and abrasive formations.
- Improved Drilling Stability and Control: The design of button bits often contributes to better hole straightness and stability during drilling, which is crucial for accurate and efficient operations.
- Cost-Effectiveness: While the initial cost might be higher than some other bit types, the extended lifespan and reduced downtime associated with button bits ultimately lead to lower overall operational costs.
what types of button bits for rock drilling?
Button bits for rock drilling come in various types, each designed for specific drilling conditions and applications.
The key differentiators lie in their connection type, button shape, and overall design.
Here are some common types of button bits that you can use for rock drilling:
- Threaded Button Bits: These bits have a threaded connection for attaching to drill rods and are commonly used in top hammer drilling for mining, tunneling, and construction. They come in various thread standards (e.g., R25, R32, T45) and head diameters.
- Tapered Button Bits: Featuring a tapered shank, these bits are designed to fit directly into tapered drill rods, typically used with handheld or pneumatic rock drills in quarrying and smaller-scale mining operations.
- DTH (Down-The-Hole) Button Bits: These bits are used with DTH hammers for drilling deeper holes in mining, water well drilling, and construction. They are characterized by their shank type that connects directly to the hammer.
- Retrac Button Bits: Designed with a skirt that retracts slightly during drilling, these bits help improve hole cleaning and reduce wear on the bit body, particularly useful in fractured or broken rock formations.
- Different Button Shapes: The tungsten carbide buttons themselves come in various shapes like spherical (domed), ballistic, conical, and flat-top, each optimized for different rock hardness and drilling aggression.
how to drill rocks with button bits?
Drilling rocks with button bits involves a systematic process that leverages the bit’s robust design to fracture and remove rock material. Achieving optimal drilling performance requires careful attention to each step, ensuring efficient energy transfer and effective cuttings removal.
Let’s delve into the key stages of this process to drill rocks using button bits.
1. Preparation and Setup
Before commencing drilling, thorough preparation is crucial for a safe and efficient operation. This involves selecting the appropriate button bit type and size based on the rock formation and drilling requirements. Ensure the bit is securely attached to the drill string or hammer, and all connections are tightened correctly.
Verify the functionality of the drilling rig, including the rotation mechanism, feed system (applying downward pressure), and the flushing system (air or water) that will remove rock cuttings from the borehole. Proper alignment of the drill string with the intended borehole location is also essential for accurate drilling.
2. Collaring the Hole
Initiating the borehole, known as collaring, requires a slow and steady approach to ensure proper alignment and prevent bit damage. Begin drilling with reduced rotation speed and feed pressure, allowing the bit to establish a stable starting point on the rock surface.
Gradually increase the rotation and pressure as the bit penetrates a few centimeters into the rock. Maintaining stability during this initial phase is critical to prevent the bit from wandering or breaking, ensuring the borehole starts in the desired location and with the correct orientation.
3. Drilling and Penetration
Once the hole is collared, the drilling process involves the continuous rotation and application of downward pressure (feed) on the button bit. The tungsten carbide buttons on the bit face impact and crush the rock, creating small fragments or cuttings.
The efficiency of penetration depends on factors such as the rock hardness, the type and condition of the button bit, the applied feed pressure, and the rotation speed. Maintaining consistent pressure and rotation is important for optimal drilling rates and to prevent excessive wear on the bit.
4. Cuttings Removal (Flushing)
Efficient removal of rock cuttings from the borehole is vital for maintaining drilling performance and preventing the bit from becoming stuck. This is typically achieved by using compressed air or water pumped through the drill string and out through flushing holes in the bit.
The flushing medium carries the cuttings up and out of the borehole. Adequate flushing ensures that the bit remains in contact with fresh rock, maximizing penetration rates and extending the lifespan of the bit by preventing excessive abrasion from accumulated debris.
5. Monitoring and Adjustment
Throughout the drilling process, it’s essential to continuously monitor various parameters, such as the drilling rate, rotation speed, feed pressure, and the effectiveness of cuttings removal.
Listen for any unusual noises or vibrations that might indicate a problem, such as bit wear, blockage, or unstable ground conditions. Based on these observations, adjustments to the drilling parameters may be necessary to optimize performance and ensure the safe and efficient completion of the borehole to the desired depth.
