Walter has now developed taps that guarantee an optimal price/performance ratio. The new duo lowers the costs for threading: The TC115 is designed for blind-hole threads and the TC216 for through-hole threads. The Walter Prototyp TC115/TC216 taps are for universal use and help reduction in tool inventory, the right choice for small and medium batch sizes in a broad range of materials from steel to aluminium wrought alloys. The Walter Prototyp TC115/TC216 with TiN coating exhibit their excellent performance, while operating at high cutting speeds with process reliability, and in addition, they offer a correspondingly longer tool life.
