Plunge cut blade

Plunge saw blade

— one of the most popular nozzles used in oscillatory instruments (primarily renovators).

The working part of such a nozzle most often has the shape of a rectangle, elongated in length (in the direction from the tool), less often — a T-shape. The cutting edge (usually straight, rarely slightly curved) is located on the opposite side of the mount — on the narrow side of the rectangle, or on the horizontal crossbar of the letter "T". Occasionally, there are other, more exotic design options. Some canvases of this type have a bend, due to which the plane of movement of the working part is below the plane of attachment; these attachments are especially useful when cutting protruding parts flush.

Anyway, nozzles of this type can have different sizes and are intended for different materials — however, in general, they are designed mainly for work under low loads, where accuracy is more important than performance; for the opposite cases, it is more reasonable to use segmented saw blades (see the relevant paragraph).
