Threaded drill rods are essentially high-strength steel tubes with male and female threads at each end, allowing them to be screwed together to form a continuous drill string. The thread design varies, but typically includes API connections like box and pin threads, ensuring a secure and reliable connection during drilling operations. These threads not only facilitate assembly and disassembly but also transmit torque from the surface down to the, enabling rotation and drilling action.

Molded fiberglass grating is available in various thicknesses, mesh patterns and dimensional sizes. Square mesh patterns enable the cutting of the panels efficiently, to accommodate a variety of floor layouts, while reducing the waste to minimal. Molded fiberglass mesh in rectangular shape is mostly used for trench covers in many industrial designs and is also a preferred grating option for walkways. The optional grit-top walking surfaces of fiberglass grating provide skid-resistance for the safety of the workers as well. The design of fiberglass grating is to ensure its reliability, in the most challenging conditions.

Coal drill bits come in various types, each tailored to specific geological conditions and drilling needs. The most common types include button bits, tungsten carbide insert (TCI) bits, and steel-to-steel (STT) bits. Button bits, with their carbide buttons on the surface, are ideal for softer rocks and coal seams due to their excellent wear resistance. TCI bits, on the other hand, are more suitable for harder formations due to their tungsten carbide inserts that provide exceptional toughness and wear resistance. STT bits, made entirely of steel, offer a cost-effective solution for less demanding drilling applications.
