Description

Improve your machining efficiency with the Dormer NPT Machine Tap. Engineered for precision, this High Speed Steel (HSS) tap is designed to create NPT threads following the ANSI B94.9 form C standard. It is specifically optimized for use in steel with a hardness of less than 850 N/mm2, making it a reliable choice for various industrial applications. This tool is built for versatility and performance. The straight flute design allows you to thread both through holes and blind holes up to 1.5xD depth. To ensure smooth operation, the bright finish helps prevent built-up-edge when working with sticky materials, maintaining tool integrity during use. Primarily intended for use on CNC machines, this Dormer tap provides the durability and hot hardness required for consistent professional results. Whether you are managing complex production runs or specific repair tasks, this HSS machine tap delivers the accuracy and reliability expected from the Dormer Pramet brand.
