Description

Achieve precise NPT threading with the Dormer Pramet HSS Machine Tap. Designed to meet ANSI B94.9 form C standards, this high-performance tool is engineered for efficiency in professional settings. The straight flute design makes it a versatile choice for threading both through holes and blind holes, reaching depths of up to 1.5xD. Built from high-quality High Speed Steel (HSS), this tap maintains excellent hot hardness during operation, ensuring reliable performance when tapping steel with a hardness of less than 850 N/mm2. The bright finish is specifically applied to help prevent built-up-edge, which is particularly useful when working with sticky materials that can otherwise clog the tool. This tap is primarily designed for use on CNC machines, providing the consistency and durability needed for industrial manufacturing. Whether you are managing complex production runs or specific repair tasks, this Dormer Pramet tool provides the professional grade results required for NPT thread applications.
