The range of hard metal tapped cutters that IGUTENSILI designs and manufactures includes the following types of articles, straight cut taps for blind holes and through holes, helical taps for blind holes, straight cut taps for blind holes and through holes for machining very hard steels up to 62 HRC, forming taps for blind and through holes. The advantage of using hard metal taps, compared to those in steel, consists of a significant increase in durability and productivity on certain types of materials and the possibility of machining hard and/or hardened steels. In particular, in the machining of abrasive materials, such as grey cast iron or aluminium-silicon alloys (Si > 10%), tool life can reach 8-10 times that of a tap in HSS. The internal passage of lubricant present in the IGUTENSILI taps allows better evacuation of the chip and to thread deep blind and through holes, up to 3XD. The advantages deriving from the use of these taps are the increase in tool life and a reduction in cycle time. The taps for very hard steels are the only solution for working hardened steels up to 62 HRC.
