väljapuurimine

Väljapuurimine is an Estonian term that translates to "drilling out" or "boring out" in English. It refers to a mechanical process of removing material from a workpiece, typically a solid object, using a rotary cutting tool called a drill bit. The primary purpose of väljapuurimine is to create a hole or to enlarge an existing one. This can be done for various reasons, such as preparing a hole for a fastener, creating a passage for fluids, or as a step in a larger manufacturing or repair process.

The process involves a drill press or a handheld drill, which rotates the drill bit at high speeds. The rotating drill bit, with its sharp cutting edges, is then advanced into the material. As the drill bit penetrates, it shaves off small chips of the material, creating the hole. The size and depth of the hole are determined by the diameter of the drill bit and the extent to which it is advanced into the workpiece. Väljapuurimine is a fundamental operation in machining and metalworking, and it is also commonly employed in woodworking, construction, and various DIY applications. Different types of drill bits are used depending on the material being drilled and the desired precision of the hole.
