Drilling is a cutting operation which uses a drill bit to cut a hole of a circular cross-section in a solid material. It is helpful in drilling water wells, oil wells, and natural gas extraction wells. Diamond drilling Kent offers various types of drilling rigs such as for land, mobile equipment mounted on trucks, tracks of trailers, or marine-based structures, useful for multiple applications.
Two significant types of drilling techniques are Percussive Drilling and Rotary Drilling. Both are unique, but the purpose remains to drill the hole, explore the surface, or define the depth.
Read on this blog to learn more about both types of drilling techniques in detail.
Percussion drilling is considered to be one of the oldest drilling methods. It uses a heavy hammering or a cable with a serious cutting bit attached to a rope and is lowered into the open hole. It is repeatedly lifted and dropped; thus, the cutting loses the soil, which gets extracted later by using a bailer.
Percussion drilling is the most common and convenient drilling technique for surface exploration. A temporary casing of steel is used to prevent the hole from collapsing. When the permanent well screen and case are installed, operators remove the temporary casing, allowing it to deepen the boreholes.
The percussion drill is operated by hand; therefore, it requires a lot of strength to get the job done. Several men pull the rope to lift and drop the bit. It takes a few pieces, which can be transported in the trunk of a car or mounted on the bed to reach the drill site. Diamond drilling Kent uses excellent drill parts that made our percussion drilling seamless.

Rotary drilling is one of the many geotechnical drilling services we offer here at Diamond Drilling Kent. It is the most widely used drilling method for small and large projects. CA Drillers look at the entire process in more detail, which we feel is necessary and worth doing because, in rotary drilling, one size does not fit all types of drilling processes.
Rotary drilling utilises a high rotation and torque, the drill bit rotating rapidly at the end of the drill pipe and boring the rocks. These drill bits are available in two forms – one is roller cone bits, and the other is fixed cutter bits. Both are suitable for high levels of use within the drilling industry. Though there are different fixed cutter bits, they are generally referred to as Polycrystalline Diamond Compact Bits (PDC).
The speed of rotations and their high frequency make rotary drilling an effective means of carving through hard and soft rock formations. This technique uses either air or drilling fluids to clear out the bore hole, cool the drill bit and reduce the friction so that it can be operated optimally.
The concrete can be rigid for any tool. Here are a few points to make your rotary hammer long-lasting
