bølgebor

Bølgebor, also known as ripple bits or wave bits, are a type of drilling tool used in certain specialized industrial applications. They are designed to create a specific type of hole or surface finish, often characterized by a series of concentric ridges or a wave-like pattern within the bore. This unique geometry is achieved through a combination of the cutting edge design and the oscillating or vibrating motion sometimes employed during the drilling process.

The primary function of bølgebor is to produce a precise and controlled surface texture. This can be beneficial in applications where a specific type of friction, sealing, or fluid flow is required. For example, they might be used in the manufacturing of certain types of seals, pumps, or fluidic components where a non-standard bore surface is advantageous. The specific design of a bølgebor can vary widely depending on the intended application and the material being drilled. Different flute designs and cutting edge angles are employed to achieve the desired wave or ripple pattern. While not as common as standard twist drills, bølgebor represent a niche tool for achieving specialized machining results.
