Nowadays, a variety of drilling methods are used to obtain holes of a certain diameter and depth in various materials. Among them, two popular techniques stand out - rotary drilling and rotary-impact drilling. This article aims to present these methods, their applications and advantages.

Rotary drilling - basics of operation and applications

Rotary drilling is one of the most popular drilling methods. The technique involves using mechanical energy to rotate the cutting tool (drill bit) around its axis. The rotary motion gradually removes material from the working surface, resulting in a hole of a certain shape and size. Rotary drilling is particularly useful when working with soft materials such as wood, plastic or gypsum. Due to its simplicity and low equipment requirements, this method is often used by amateurs and professionals for domestic work, such as installing shelves, hangers or fasteners.

Rotary-impact drilling - operating principle and applications

Rotary-impact drilling is an advanced drilling technique that combines rotary motion with reciprocating motion. In practice, this means that in addition to the classic rotary motion, the drill performs reciprocating motions, which results in a much higher thrust force on the material. As a result, rotary-impact drilling allows for faster and more precise drilling of holes in hard materials such as concrete, brick or stone. Rotary-impact drilling is particularly popular in the construction, industrial and mining industries, where high power and productivity are required.

What makes these drilling methods different?

Rotary percussion drilling is characterized by much higher productivity and the ability to penetrate hard materials than rotary drilling. By using a reciprocating motion, this method allows for faster and more efficient removal of material, saving time and energy. Rotary-impact drilling is also more precise, making it an essential tool for professionals.
