Claw bits stand out in drilling operations with their exceptional ability to achieve rapid penetration, matching the swift drilling speed of drag bits while boasting the rugged durability of roller rock bits. A key advantage lies in their field-replaceable bullet-shaped cutters, which allow for quick maintenance without halting operations for extended periods. This unique combination of speed, toughness, and convenience makes them a versatile choice across various geological formations, enhancing efficiency and reducing downtime in drilling projects.
Claw bit offers rapid penetration, drilling speed as fast as that of a drag bit, and being as tough as a roller rock bit. They feature field replaceable bullet shaped cutters. Their cutters, which are economical, inexpensive and replaceable, are designed to rotate in their blocks to provide a self sharpening effect, thus extending the life of the bit and reducing torque. They have one circulation hole per cutter, in order to provide maximum hole cleaning.Claw bits body, cutters, and pilots can be ordered separately or assembled. We can offer claw bits in different sizes with a number of thread connections.
• A solid one piece heat treated, 4140 alloy steel body for bit strength & durability;
• CNC threaded machining for proper installation &use;
• Forgings are milled to better seat the carbide inserts.
• Select tungsten carbide inserts 5.5mm thick are standard.
• Relief is hand-ground behind carbide inserts for maximum performance.
