Drawplate Triangle 87% 3mm-1mm 20 Holes

The Triangle Drawplate SP 139 features 20 precisely graduated holes for drawing soft non-ferrous wire and stock into a consistent isosceles triangle profile. The two equal sides of each triangular hole measure 87% of the base (factory ratio SP 139), yielding a hole range from 3 mm × 2.6 mm down to 1 mm × 0.87 mm. Each hole is machined to exacting tolerances, ensuring smooth, even draw-downs with minimal resistance and reliable size progression across the full range.

Made from properly hardened steel by an Italian manufacturer with over 40 years of experience producing professional-grade drawplates, this plate combines modern machine tooling with old-world attention to detail. It is designed for use with soft non-ferrous metals including gold, silver, platinum, palladium, and copper alloys.
