Description

The Dormer EX401.1/4 Series EX40 machine tap is engineered for high-performance threading applications. Built with premium HSS-E-PM powder metal high speed cobalt, this tool offers superior performance and extended tool life compared to standard taps. The specialized spiral flute design is specifically developed for efficient threading in blind holes, ensuring smooth chip evacuation and precision. This tap features a bright finish that prevents workpiece material from sticking to the cutting edge, which maintains tool integrity during heavy use. It is a highly versatile solution for various metalworking tasks. While it is the first choice for tapping aluminium, it is also suitable for working with steel, stainless steels, and cast iron. Manufactured to DIN Standards, this tool meets the rigorous requirements of the German Institute for Standardization, providing reliable quality for professional workshops and industrial environments.
