Applications
This tap is specifically configured for blind hole operations in non-ferrous metals. It is highly suitable for the efficient machining of wrought aluminum alloys, cast aluminum alloys with less than 12 percent silicon, as well as copper and brass materials. The tool thoroughly supports smooth workflows in professional mechanical engineering and machining operations.
Special features
The construction from HSS-E steel supports consistent machining performance in softer metals. By being tailored to blind holes and featuring the metric ISO thread profile with a 60-degree flank angle, the tap represents a reliable tool for standardized threaded connections.
