The Triangle Drawplate – 87% Isosceles, 6 mm–3 mm, 31 Holes is a precision steel drawing plate designed for reducing and shaping wire into a consistent triangular cross-section. This isosceles triangle profile features two equal sides that measure 87% of the base, corresponding to factory ratio designation SP 139. The plate offers 31 precisely graduated holes, with the largest opening measuring 6 mm × 5.2 mm and the smallest at 3 mm × 2.6 mm, allowing for smooth, incremental draw-downs with minimal stress on the metal.

Made of properly hardened steel in Italy, this drawplate is built to handle repeated use with soft non-ferrous metals including gold, silver, platinum, palladium, and copper alloys. The Italian manufacturer behind these plates has been producing professional-grade drawplates for over 40 years, combining modern machining with meticulous old-world craftsmanship. Every hole is precisely graduated to ensure even, controlled reductions with each pass.
