FIELD: mining; machine building.
SUBSTANCE: group of inventions relates to mining machines, in particular, to mining machine cutter. Assembly cutter for mining machine contains: holder containing first surface, second surface, and channel passing between them. Cutter comprises a first end, a second end and a stop, the cutter further comprising a sharpened end near the first end, a shank near the second end and a collar, located between sharp end and shank. Shank is located in the channel of the holder and has an axis of the shank. Striker interacts with the first surface of the holder; the shank has a projection adjacent to the second end. Lock comprises groove and resilient element. Groove interacts with the protrusion section, the resilient element interacts with the second surface of the holder and shifts the retainer along the axis of the shank and from the holder.
EFFECT: technical result is reliable connection of cutter elements.
