Ibyiciro byinshi byagutse byibikoresho byo gusoza no gusya birahari, nko gukata hagati no kutagabanya hagati (niba urusyo rushobora gufata ibice); no gutondekanya ukurikije umubare w'imyironge; na helix inguni; ukoresheje ibikoresho; no gutwikira ibikoresho. Buri cyiciro gishobora kugabanywa kubisobanuro byihariye na geometrie idasanzwe.
Inguni izwi cyane ya helix, cyane cyane mugukata muri rusange ibikoresho byicyuma, ni 30 °. Kurangizaurusyo, ni ibisanzwe kubona izenguruka cyane, hamwe na helix inguni 45 ° cyangwa 60 °.Umwironge wanyuma(helix angle 0 °) bikoreshwa mubikorwa bidasanzwe, nko gusya plastike cyangwa ibice bya epoxy nikirahure. Uruganda rukora umwironge kandi rwakoreshejwe mu mateka mu gutema ibyuma mbere yo kuvumbura urusyo rwa feri ya nyuma ya Carl A. Bergstrom wo muri Weldon Tool Company mu 1918.
Hariho urusyo rwanyuma rufite flute helix cyangwa pseudo-random helix inguni, hamwe na geometrike idahagarara, kugirango ifashe gucamo ibice mo uduce duto mugihe cyo gutema (kunoza kwimuka kwa chip no kugabanya ibyago byo guterana) no kugabanya uruhare rwibikoresho mugukata gukomeye. Ibishushanyo bimwe bigezweho nabyo birimo ibintu bito nka mfuruka chamfer na chipbreaker. Mugihe gihenze cyane, kubera igishushanyo mbonera nuburyo bwo gukora, nkibyourusyoirashobora kumara igihe kinini kubera kwambara gake no kuzamura umusaruro muriimashini yihuta(HSM) Porogaramu.
Biragenda biba ibisanzwe kumashini gakondo arangiza asimburwa nibindi byinjiza nezaibikoresho byo gukata.
Urusyo rwanyuma rugurishwa haba mubwami bwa metero na metric no kugabanya diameter. Muri Amerika, metric iraboneka byoroshye, ariko ikoreshwa mumaduka amwe gusa ntabwo ayandi; muri Kanada, kubera iki gihugu cyegereye Amerika, ni ko biri no. Muri Aziya no mu Burayi, ibipimo bya metero ni bisanzwe.
