قالب تقليص وقضيب دفع لمطاط الخواتم (ديلرين)

The Delrin reducing die fits perfectly and the 16 countersunk holes make changing sizes effortless. I've already used it several times and it locks into my ring stretcher without any burrs or snags.

I was a bit skeptical about the countersunk holes at first, but they make aligning the rod so much easier. The bur-free finish is a nice touch, and it slides into my stretcher perfectly.

The Delrin material feels super smooth and stable in hand, and the countersunk holes align perfectly with my ring sizes—no snagging at all. I've run several rings through and the push rod glides without any wobble. Exactly what I needed for fine adjustments.
