RUKO Terraja para rosca a izquierdas SCE-DIN22568-HSS-60°-M12x1.75mm

This RUKO round die is engineered for cutting left-hand metric coarse threads, a less common but essential operation for specific mechanical assemblies where reverse rotation is required. Unlike standard right-hand dies, this tool ensures precise thread geometry for M12 fasteners with a 1.75 mm pitch, meeting DIN 22568 specifications.

Highlights

• Left-hand thread direction for specialized applications
• High-speed steel (HSS) construction for durability
• Ground cutting edges for accuracy and clean threads
• Compatible with standard die stocks

In daily use

Ideal for repair and production tasks involving left-hand threads on steel, cast iron, non-ferrous metals, and plastics. The bright finish reduces friction and improves chip flow, while the 6g tolerance class ensures consistent thread fit.
