    Claw bit offers rapid penetration, drilling speed asfaster than 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 thelife 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.
