VOLKEL Thread circular round dies are used for producing external threads. Round dies are round and usually have three or more cutting edges. They are either used for manual use of die holders or clamped into the quill to use in a turning lathe.
The chips are discharged through the plane holes in round dies. VOLKEL Round dies are available slotted or solid, with solid being the most commonly used style. The groove in slotted round dies allows these to be adjusted if worn while solid dies are able to produce more precise pitch of thread. Dies also come in round solid circular form or Hexagon die nut Form.
BSP threads can be categorized into two main types: parallel (BSP) and tapered (BSPT). As the name suggests, BSP threads have a parallel uniform diameter along their entire length, while BSPT threads have a tapered diameter from one end to another that tapers at a degree of 1 inch per 16 inches. British Standard Pipe (BSP)— a thread standard widely used internationally for plumbing and pipe-fitting applications.
