Standard Button Rock Drill Bits

Standard button rock drill bits rank as the most frequently used type. With carbide buttons on the tips, they excel at drilling through hard rock formations. These bits come in various sizes, making them suitable for both surface and underground drilling operations.

Retrac Button Rock Drill Bits

Retrac button rock drill bits feature a retractable design that allows the bit to adjust its length as necessary. This capability ensures continuous contact with the rock surface, enhancing the drilling efficiency. Ideal for loose rock formations, these bits are widely employed in mining and tunneling projects.

Drop Center Button Rock Drill Bits

Drop center button rock drill bits have a specialized slightly concave tip, creating a central depression on the rock surface. This design facilitates stable contact with the rock, thereby increasing drilling efficiency. They are particularly effective for hard rock formations and are commonly utilized in quarrying and mining operations. For optimal safety and efficacy in mining and tunneling tasks, selecting appropriate Mining Drill Tools is essential.

Ballistic Button Rock Drill Bits

Ballistic button rock drill bits are engineered with multiple carbide buttons, resulting in increased impact force and expedited drilling. This type of bit performs best with medium-hard rock formations and sees common usage in quarrying and mining operations.

Spherical Button Rock Drill Bits

Spherical button rock drill bits are characterized by numerous spherical carbide buttons on their tips, which confer high impact force and exceptional wear resistance. Such bits excel when drilling through hard and abrasive rock formations and are frequently used in both mining and tunneling activities.
