Description
The Triangle Drawplate SP 139 features 31 precisely graduated holes shaped as isosceles triangles, where the two equal sides measure 87% of the base. The largest hole measures 12mm × 10.4mm and the smallest measures 9mm × 7.8mm, providing a consistent, evenly stepped range for reducing and shaping triangular wire profiles.
Made from properly hardened steel by an Italian manufacturer with over 40 years of experience producing professional-grade drawplates, this plate is built for reliable performance with soft non-ferrous metals. Modern machine tooling combined with traditional craftsmanship ensures that every hole is precisely formed for smooth, controlled draw-downs.
