spiraalboren
Spiraalboren, also known as twist drills, are the most common type of drill bit used for creating round holes in various materials. They are characterized by their helical grooves, called flutes, which run along the body of the drill. These flutes serve two primary functions: they create cutting edges that remove material, and they provide a channel for the chips and debris generated during drilling to escape the hole.
The geometry of a spiraalboor is crucial to its performance. The point angle, the angle at the
Spiraalboren are typically made from hardened steel. High-speed steel (HSS) is a common material, known for its
The effective use of a spiraalboor involves selecting the correct size and type for the material being
