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.

FRP pipes are composite structures composed of a matrix of resin and glass fibers. The glass fibers, which give the pipe its strength, are intricately woven or layered, while the resin serves as a bonding agent, providing durability and resistance to environmental factors. The combination of these two elements results in a material that is not only lightweight but also incredibly strong, making it ideal for high-pressure and corrosive environments.

There are various types of rotary hammer drill bits, each tailored to specific applications. SDS (Steinbock-Dreh-Schaft or 'handle-drill-shaft' in German) bits are the most common, featuring a locking mechanism that allows quick bit changes.
