REED used its 120+ years of die-making experience to select the best materials, methods, and CNC production for its Universal Dies. These dies fit REED's 5301PD power drive, RIDGID® 300, 300 Compact, 535, 535 Automatic, 1215, 1822-I, 1224 plus the REED R811 Universal Die Head. Choose from REED's full line of High Speed Steel (HSS) universal dies in geometries for NPT, NPSM and BSPT. HSS dies last longer than alloy dies because HSS universal dies withstand high temperature without losing hardness. This feature allows them to cut faster than the alloy at room temperature.
