These taps have no flutes except as optionally designed with one or more lubrication grooves. The thread form is lobed so there is a finite number of points contacting the work. This tap does not cut metal, so it is 'chipless' and consequently will not cause a chip problem. The tool forms the thread by extrusion, thus thread size can be closely maintained. The fluteless design allows high quality threads, faster tapping speeds, higher production and generates no chips, which simplifies tapping of blind bottoming holes (threads can be formed the full depth of the hole).
- Item Features
- Improved thread quality and strength due to fluteless design of tap allows, greater fastener strength in threaded product
- Tapping speeds can be increased as much as double that of conventional cutting taps more tapped holes per hour
- Thread forming (over thread cutting) eliminates costly and time consuming chip clean up and disposal
- Improved tap life even in abrasive materials and no cutting edges to get dull
- Lubrication grooves allow forced passage of air and lubricant when tapping
- Simplifies tapping of problematic blind bottoming holes where adequate chip clearance is impossible with chip producing cutting taps
