Reed used its 115+ 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 and 5401TMSO threading machine, Ridgid® 300, 300 compact, 535, 535 automatic, 1215, 1822-I, 1224 plus the Reed R811 universal die head. Reed’s high speed steel (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.
