This 2-piece threading kit provides the essential tools for professional-grade threading tasks involving the M27 x 3mm size. The set consists of a high-speed steel (HSS) machine tap and a matching round die, both ground to precision standards to ensure a perfect fit for metric coarse fasteners.
Because these tools are made from industrial-grade HSS, they are capable of handling the high torque required for large-diameter threading in various metal types. The M27 size with a 3.0mm pitch is commonly used in heavy machinery and structural applications. The plug tap allows for efficient threading of internal holes, while the solid round die is used for creating or cleaning external threads on cylindrical workpieces. This set is a reliable choice for engineers, machinists, and maintenance professionals who require accurate, repeatable results.
