A reciprocal ram carries a metallic cup on an end thereof axially through a die pack opening and a die ring thereof in a working metal forming stroke, the cup is stripped therefrom and the ram moves reversely through the die ring in a return stroke. An annular lubricant nozzle surrounding the die pack opening forwardly adjacent the die ring directs an annular flow of lubricant continuously axially along and against an angled die ring entrance surface to a die ring forming surface during presence of the cup therein, and over the die ring forming surface and through natural adherence along a die ring angled exit surface during lack of presence of the cup regardless of the ram position in its strokes. The nozzle also preferably directs the lubricant constantly impinging on an exposed leading end surface of the die ring and preferably the outer of nozzle angled and parallel internal annular surfaces is formed by a separately mounted lubricant distribution ring, the exact ring mounting determining the nozzle lubricant direction and flow volume.
