fläktfräser

Fläktfräser is a Swedish term that translates to "fan milling cutter" or "fan milling bit" in English. It refers to a type of milling cutter specifically designed for creating grooves or slots in materials, often used in woodworking and metalworking. The distinguishing feature of a fläktfräser is its shape, which resembles a fan or a propeller. This design allows for efficient chip evacuation during the milling process, preventing clogging and enabling a smoother cut.

These cutters typically have multiple cutting edges arranged in a helical or radial pattern. The fan-like configuration helps to push the removed material away from the cutting area, which is particularly beneficial when working with softer materials or when deep cuts are required. The design can vary, with some fläktfräser having a relatively flat profile, while others may have a more pronounced curve to their blades.

Fläktfräser are commonly employed in applications such as creating keyways, splines, or decorative grooves. Their effectiveness in clearing chips contributes to a cleaner workpiece and can reduce the risk of tool breakage caused by overheating or material buildup. The choice of material and the specific geometry of the fläktfräser will depend on the material being machined and the desired outcome of the milling operation.
