RUKO SMU-DIN382 M18x2,5mm 6g Terraja redonda rectificada

For machinists and maintenance technicians cutting external M18x2.5 metric threads on steel, non-ferrous metal or plastic workpieces, this RUKO round die delivers precise, clean threads to tolerance class 6g. It is used with a suitable die stock in a workshop or on-site repair environment.

Key specifications

• Thread type: Metric coarse, nominal diameter 18 mm, pitch 2.5 mm
• Thread standard: DIN 382, profile ISO 68-1
• Material: HSS-G (high-speed steel, ground)
• Outer diameter: 45 mm, thickness: 14 mm
• Cutting direction: right-hand, tolerance class 6g
• Surface: bright finish

Why choose it

The ground HSS-G construction ensures sharp cutting edges and long tool life when threading unalloyed and low-alloyed steels, non-ferrous metals and plastics. The 6g tolerance class produces threads that fit standard metric nuts and tapped holes reliably.

Ideal use cases

• Creating external threads on bolts, studs and shafts
• Repairing damaged threads on existing fasteners
• Custom thread cutting in maintenance and prototyping

Good to know

The die requires a die stock with a 45 mm opening. For best results, use cutting oil and start with a chamfered workpiece end.
