Kune mapoka akasiyana-siyana ezvishandiso zvekugaya zvekupedzisira uye zvechiso, zvakaita sekucheka pakati kana kusacheka pakati (kana chigayo chinogona kuchekwa zvakadzika); uye kupatsanurwa nenhamba yeflutes; ne helix angle; nezvinhu; uye ne coating material. Chikamu chimwe nechimwe chinogona kupatsanurwa zvakare nekushandiswa kwacho uye geometry yakakosha.
Kona ye helix inozivikanwa zvikuru, kunyanya pakucheka zvinhu zvesimbi, ndeye 30°. Yekupedzisazvigayo zvekupedzisira, zvakajairika kuona denderedzwa rakamanikana, rine makona emota ari 45° kana 60°.Zvigayo zvemagetsi zveflute zvakananga(helix angle 0°) inoshandiswa mumabasa akakosha, semapurasitiki ekugaya kana zvinhu zvakagadzirwa ne epoxy negirazi. Zvigayo zvemagetsi zvakatwasuka zvaishandiswawo kare pakucheka simbi zvisati zvagadzirwa naCarl A. Bergstrom weWeldon Tool Company muna 1918.
Kune magayo ekupedzisira ane flute helix inochinja-chinja kana pseudo-random helix angle, uye discontinuous flute geometries, kubatsira kupwanya zvinhu kuita zvidimbu zvidiki panguva yekucheka (kuvandudza kubuda kwemachipisi uye kuderedza njodzi yekuvharika) uye kuderedza kushanda kwezvishandiso pakucheka kukuru. Mamwe madhizaini emazuva ano anosanganisirawo zvinhu zvidiki zvakaita sekona chamfer nechipbreaker. Kunyange zvazvo zvichidhura, nekuda kwekugadzirwa kwakaoma uye maitiro ekugadzira, zvakadai sezvigayo zvekupedzisirainogona kugara kwenguva yakareba nekuda kwekusakara kushoma uye kuwedzera kugona kwayo mumachining ekumhanya kwakanyanya(HSM) mashandisirwo.
Zviri kuramba zvichiwedzera kuwanda kuti zvigayo zvechinyakare zvakasimba zvitsiviwe nezvinoiswa zvinodhura zvishomamaturusi ekucheka(izvo, kunyange zvazvo zvichidhura pakutanga, zvinoderedza nguva yekuchinja maturusi uye zvinoita kuti zvive nyore kutsiva mipendero yakasakara kana yakatyoka pane kushandisa chishandiso chose).
Zvigayo zvekupedzisira zvinotengeswa muhukuru hweimperial nemetric shank uye cutting diameters. MuUSA, metric inowanikwa nyore nyore, asi inoshandiswa chete mune mamwe mashopu emuchina kwete kune mamwe; muCanada, nekuda kwekuva pedyo kwenyika neUS, zvakafanana. MuAsia neEurope, metric diameters ndiyo yakajairika.
