Pattern cutter

Abstract

Disclosed here in the present utility model is a pattern cutter. The pattern cutter includes a base and blade. The blade is located on the base. The blade forms the shape of pattern to be cut. The said base and blade are of one-piece structure, which is machined to shape at one go through die-casting process. The height of the said blade is greater than or equal to 2.5 mm on the base. The angle of the cutting edge of blade is smaller than or equal to 60°. The said blade is surfaced with a plating coat. The present utility model is characterized by simple and rational construction, easy to make, low cost, high product accuracy and good consistency, with a wide range of adaptability and better market prospect.
