Button drill bits, on the other hand, are characterized by the array of small, diamond- or tungsten-carbide-coated buttons strategically positioned on the bit face. These buttons act as cutting tools, wearing down the rock surface as the bit rotates. In the case of rock button bits, the carbide material is exceptionally hard and wear-resistant, capable of withstanding the harsh conditions encountered in drilling through various types of rocks.

A tapered drill rod is essentially a steel bar with a gradual reduction in diameter from one end to the other. This design feature enables smoother and more efficient, as the taper allows for better torque transfer and reduces the chances of stick-slip occurrences during drilling. The taper also aids in the insertion and extraction of drill bits, making the process faster and less labor-intensive.
