Product Catalog
WTC manufactures patented Polygon Box Tools which are utilized to machine Polygon contours both internal and external in metal. Currently ten models for both automatic screw machines and conventional lathes are in production. A typical application would involve performing such operations of turning or boring hexes, squares, flats or any other polygon shape concurrent with other machining operations, yielding a finished part from one machine cycle. Thus resulting in the elimination of costly secondary operations.
See our product application descriptions below.
