Zvikamu zvakati wandei zvematurusi ekupedzisira uye ekugadzira kumeso aripo, akadai sekucheka kwepakati maringe nekusachekwa kwepakati (kunyangwe chigayo chinogona kutora kucheka cheka); uye kuisa muzvikamu neuwandu hwenyere; by helix angle; by material; uye nokunamira zvinhu. Chikamu chega chega chinogona kupatsanurwa zvakare nechaiyo application uye yakakosha geometry.
Iyo yakakurumbira helix angle, kunyanya yekucheka kwese kwesimbi zvinhu, ndeye 30 °. Kupedzisakupera zvigayo, zvakajairika kuona zvakanyanya kutenderera kutenderera, nemakona ehelix 45° kana 60°.Nyere dzakatwasuka(helix angle 0 °) anoshandiswa mukushandisa kwakakosha, senge mapurasitiki ekugayo kana macomposites epoxy uye girazi. Nyere dzakatwasuka dzekupedzisira zvigayo zvakashandiswawo munhoroondo yekucheka simbi isati yagadzirwa yehelical flute end mill naCarl A. Bergstrom weWeldon Tool Company muna 1918.
Kune maguyo ekupedzisira ane anosiyana nenyere helix kana pseudo-random helix angle, uye discontinuous nyere geometries, kubatsira kuputsa zvinhu kuita zvidimbu zvidiki uchicheka (kuvandudza chip evacuation uye kuderedza njodzi yekujairira) uye kuderedza kushandiswa kwechishandiso pakucheka kukuru. Mamwe magadzirirwo emazuva ano anosanganisirawo madiki madiki senge kona chamfer uye chipbreaker. Kunyange zvichidhura zvakanyanya, nekuda kwekunyanya kuomarara dhizaini uye maitiro ekugadzira, akadarokupera zvigayoinogona kugara kwenguva refu nekuda kwekupfeka kushoma uye kugadzirisa chibereko mukatihigh speed machining(HSM) zvikumbiro.
Zviri kuwedzera kuwanda kuti zvigayo zvechinyakare zvigayo zvitsiviwa nezvigayo zvisingadhure zvinoiswamidziyo yekucheka(izvo, kunyange zvichidhura pakutanga, kuderedza-shanduko-shanduko nguva uye kubvumira kuti nyore kutsiva yakasakara kana yakatyoka yekucheka mipendero pane chishandiso chose).
Zvigayo zvekupedzisira zvinotengeswa mune zvese zveumambo uye metric shank uye kucheka madhayamita. MuU.SA, metric inowanikwa nyore, asi inongoshandiswa mune zvimwe zvitoro zvemuchina uye kwete zvimwe; muCanada, nekuda kwekuswedera kwenyika kuUS, zvakafanana ndezvechokwadi. MuAsia neEurope, metric madhayamita akajairwa.
