  This depends very much on the application

  • Tapping is better suited for small diameter, high volume applications

  • Where components are already threaded and require clearing or oversizing it is very difficult to "pick up" an existing thread accurately using single-point threaders.

  • Generally speaking, Tapping returns far greater consistency over larger volumes. It is often the case that we are requested to retap work which has been single-pointed following the discovery of innaccuracies in the finished components.

  • Cost effectiveness is a factor which weighs heavily in favour of Tapping. It is usually possible to set up tapping operations in a fairly short space of time. Also, the tapping process can be carried out by semi-skilled labour, ultimately reducing cost to the customer.

  • The occurrence of Pitch Error is reduced considerably when tapping is done as opposed to single-pointing.

  • Single point threading is useful for larger diameters with comparatively short thread lengths. It is particularly suitable for Blind Hole threading in items such as Cap Nuts and Dome Nuts. Higher value components are often threaded in this way, usually in cases where machining costs are a relatively insignificant factor compared to those of the raw material.
