Cossinete RUKO SCE-DIN223-MF12x1,25 mm rosca fina métrica, 12 mm x 1,25 mm passo, HSS, DIN 223

This RUKO round die cuts precise metric fine external threads with a 12 mm diameter and 1.25 mm pitch. Unlike standard coarse-thread dies, the fine pitch provides finer adjustment and higher strength in thin-walled or high-vibration applications. Manufactured to DIN 223 from high-speed steel with ground threads, it delivers clean, accurate threads in unalloyed and alloyed steels, cast iron, and non-ferrous metals.

Highlights

• Metric fine thread MF12 x 1.25 mm per DIN 223
• High-speed steel (HSS) with ground threads for durability
• Right-hand cutting direction, tolerance class 6g
• Outer diameter 38 mm, thickness 10 mm
• For manual or low-speed machine operation with a die stock (not included)

In daily use

The bright, uncoated surface reduces friction and allows easy chip evacuation. Use a suitable die stock to hold the die securely and apply steady pressure with cutting oil for best results. The 60° metric ISO thread profile ensures compatibility with standard metric fasteners.
