RUKO 242259 Portafiliere DIN 225, 25 × 9 mm

RUKO 242259 is a DIN 225 holder for round threading dies, in size 25 with 9 mm die thickness. Its overall length is 210 mm. The manufacturer specifies the metric thread range M7–M9 for this size. The housing is die-cast zinc and the handles are steel. The exact variant has SAP number 1200012055 and a net product weight of 120 g.

The holder is designed for closed and split round dies used in manual external-thread cutting. Five clamping screws secure the die in the housing, and one of the steel handles can be unscrewed. Match the die outer size and thickness to the holder before fitting it; the thread range alone does not describe the mounting dimensions. This is the die holder, with the threading die selected separately for the required thread.
