kiertovää

Kiertovää is a Finnish term that translates to "rotary drill" or "rotary bit" in English. It refers to a tool used in drilling operations that employs a rotating motion to cut through material. This type of drill is distinct from percussive drills that use hammering actions. Kiertovää are commonly found in various applications, including construction, mining, and woodworking.

The design of a kiertovää typically involves a hardened cutting edge, often made of materials like steel, carbide, or diamond, depending on the material being drilled. The rotation of the bit, powered by a drill motor, allows the cutting edges to abrade and remove material, creating a hole. Different types of kiertovää exist for specific purposes. For instance, twist drills are prevalent for general-purpose hole making in metal and wood, featuring helical flutes to clear debris. Masonry bits, on the other hand, have a more robust tip designed to penetrate hard materials like concrete and brick.

The effectiveness of a kiertovää is influenced by factors such as its size, shape, material composition, and the speed of rotation. Proper application and maintenance are crucial for efficient drilling and to prolong the tool's lifespan.
