The NK-1 and NK-2 shears are designed for cutting steel or colored metal sheets or strips. They can be used in metalwork or sheet metal work. The NK-1 scissors are attached directly to the table by screwing them or in the jaws of the vice, while the NK-2 scissors can only be attached to the table. Circular knives are made of tool steel and hardened in the heat treatment process. The NK-1 and NK-2 shears, apart from cutting in a straight line, allow you to cut sheet metal perfectly on curved (arched) lines.

The NK-1 shears work together with the attachment-cutting device PNK-1.

The PNK-1 attachment is intended for cutting a disc with steel sheet up to 1.0 mm thick or sheet with non-ferrous metals up to 2.0 mm. The diameter of the cut out disk is from 50 to 300 mm. The attachment is clamped in the jaws of the vice. The weight of the PNK-1 attachment is 3.80 kg.
