Uppoporakruunujen suunnittelussa tavoitteena on aina isompi määrä porattuja metrejä kaikissa olosuhteissa. Kruunun teräpään pituus optimoidaan siten, että kovametallinastojen tueksi saadaan mahdollisimman tukeva teräsrakenne. Kruunun otsapinnan huuhtelu-urituksella parannetaan nastojen huuhtelua ja kivenirrotuksen tehokkuutta.
