Yamawa AXE-HT tap for aluminium creates more easily ejected swarf
The Yamawa AXE-HT tap for aluminium casting alloys threading has an axe shape cutting edge. The design is aimed at removing all possible chipping problems that may affect consistent performance when threading aluminium.
The Yamawa AXE-HT cutting geometry has a negative rake angle to increase its strength and generate short chips of a thicker than usual section that can be ejected more easily. The aim is to achieve a longer tool life and more stable machining both on blind and through holes.
The taps have a recommended cutting speed of 7 to 12 m/min on transfer machines and 20 to 30 m/min on synchro-rigid machines.
As well as the AXE-HT, the Yamawa range for aluminium threads includes the Green Ring taps AL-SP for blind holes; LA-O for through holes and the Ultra Fast for high speed threading.
