Conventional drilling method consists of several types of drilling techniques such as hollow-stem auger drilling, cable-tool drilling and rotary drilling. Hollow-stem auger techniques are commonly used for subsurface environmental projects. Rotary drilling techniques include direct mud rotary, air rotary, air rotary with a casing driver, and dual-wall reverse circulation.
Conventional hard dies are designed to produce a single stamping in a single hit or through the course of multiple hits or stations. It is fed manually or automated from coil for high-volume production. A die set consists of a top and bottom steel plates, which is held in vertical alignment by two or more guide pins and bushings.
