Ibikoresho byinshi byimperuka- Ibikoresho byo gusya mumaso bihari, nko gukata hagati muburyo bwo gukata hagati (niba urusyo rushobora gufata imigano ishimishije); no gushyira mu byicama mubyironge; by helix inguni; n'ibikoresho; no mu bikoresho. Buri cyiciro gishobora kuba kirimo kugabanwa na porogaramu yihariye na geometrie idasanzwe.
Inguni izwi cyane ya Helix, cyane cyane yo guca muri rusange ibikoresho byicyuma, ni 30 °. Kurangizaimperuka, birasanzwe kubona akajagari gakomeye, hamwe na Helix impande 45 ° cyangwa 60 °.Umwironge ugororotse urangiza. Umwironga ugororotse urangije nanone wakoreshejwe mumateka kugirango utere imbere yicyuma mbere yuko imvura yinjira muri Carl A. Bergtrom Mobile Tool Tool muri 1918.
Habaho imperuka ya pararil hamwe na varix helix cyangwa pseudo-randot helix inguni, kandi igambirira. Kugabanya ibyago byo kwimura Ibishushanyo bimwe bigezweho birimo ibintu bito nka chamfer na chipbreaker. Mugihe bihenze, bitewe nuburyo bwo gushushanya no gukora, gutyaimperukairashobora kumara igihe kirekire kubera kwambara no kunoza umusaruro muriUmuvuduko mwinshi(HSM) Porogaramu.
Biragenda bikunze kugaragara kumuryango gakondo gakondo kugirango usimburwe nibiciro byinshi byinjijweGukata ibikoresho.
Uruhinja rwanyuma rugurishwa muri kasheal kandi rwa metric shank no gukata diameters. Muri Amerika, Metric iraboneka byoroshye, ariko ikoreshwa gusa mumaduka amwe nabi ntabwo ari abandi; Muri Kanada, bitewe no kuba hafi yigihugu kuri Amerika, kimwe niko nukuri. Muri Aziya n'Uburayi, imiyoboro ya metric ni isanzwe.
