Tapping into cast iron and abrasive materials

Yamawa has developed material specific taps to solve the problems related to the machining of cast iron.

The range includes: GG-HT taps for general machining purposes; Z-Pro GGST and GGST CH taps – a state-of-the-art of technology for medium tapping speeds; and CT-FC carbide taps.

GG-HT taps (also known as ‘white ring taps’) are straight fluted taps intended for cast iron on everything from CNC machining centres to drilling machines. The cutting edge features a geometry with high rigidity rake angle; nitride treatment allows reaching up to 1,300 HV surface hardness, thus ensuring high wear resistance.

Z-Pro GGST and GGST CH taps are part of the Yamawa Z-Pro Series of high performance taps. The GGST is a straight fluted variant for use a medium tapping speeds that delivers excellent internal thread surface thanks to optimised cutting geometry and a special coating. GGST CH with internal coolant hole is the best choice for the machining of automotive parts when high tapping speeds are required to increase productivity. The internal cooling promotes chip evacuation and finished threads cleaning. Two different chamfers, C (2.5P) and E (1.5P), are available.

Completing the series for solutions for cast iron and abrasive materials are CT-FC taps, manufactured from carbide with a specific design based on GG-HT geometry for extremely long and stable tool life. CT-FC taps can last up to 50 times longer than HSS conventional taps.
