löökpuurimist
Löökpuurimist, also known as percussion drilling or hammering drilling, is a drilling method that uses a repeated impact force to break and penetrate material. Instead of continuous rotation like conventional drilling, a tool strikes the surface repeatedly. This impact energy is transmitted through the drill bit, causing the material to fracture and be removed. The process often involves a mechanism that generates these impacts, such as a pneumatic hammer, a hydraulic ram, or a manual striking tool. The force of the blows, the frequency of the impacts, and the type of drill bit used are all important factors determining the effectiveness of löökpuurimist. This technique is particularly useful in hard, brittle, or dense materials where conventional drilling might be inefficient or cause excessive wear on the equipment. Applications can be found in construction, mining, and geological surveying. The debris generated by the impacts is typically cleared by flushing with water or air, or through specialized bit designs.
