How to Choose the Right Rock Drill Bit?
Choosing the right rock drill bit starts with your drilling equipment and the required hole size. Use the following five factors to identify a compatible bit and select a suitable cutting design for your rock conditions.
Drilling System
Start by identifying your drilling method. Rock drill bits are mainly used for top hammer or DTH drilling systems. Each system requires a compatible bit design.
Equipment Compatibility
Confirm your drilling equipment and connection type. For top hammer systems, check the tapered angle or thread size. For DTH systems, verify the hammer model and bit shank compatibility.
Hole Diameter
Determine the required hole diameter in millimeters or inches. The selected bit size should match your drilling requirements and the operating capabilities of your equipment.
Rock Conditions
Consider rock hardness, abrasiveness, and fracturing. These conditions influence carbide button geometry, bit wear resistance, penetration performance, and drilling stability.
Bit Design
Choose a suitable cutting design based on your equipment and rock conditions. Available options may include button, cross, chisel, and retrac designs for compatible drilling systems.
