1. Uhlobo lwe-Convex: Le bits iza ngezindlela ezimbili, umphathi oyedwa kanye no-double boss.Eyakamuva isetshenziswa kakhulu kumabhithi e-DDP anobubanzi obukhulu.
Ama-Convex DDR angagcina izinga eliphezulu lokumba lapho kubholwa amatshe aqinile naqinile abrasive, kodwa ukucaba kokumba kubi, ngakho abufaneleki ubunjiniyela bokumba obudinga ukucaba okuphezulu kwezimbobo eziqhumayo.
I-2, uhlobo oluyisicaba: lesi sakhiwo sokubhoboza siqinile futhi sihlala isikhathi eside, silungele ukubhoboza idwala eliqinile neliqine kakhulu, kodwa futhi kufanelekile ukubhoboza imbobo ephansi akuzona izidingo eziphakeme zetshe eliqinile eliphakathi nendawo kanye nedwala elithambile.
3. Uhlobo lwe-Concave: ubuso bokuphela kwekhanda elincane elinalesi simo linokucindezeleka kwe-conical, okwakhiwa yi-bit inqubo yokubhoboza ukuze kugcinwe ukusebenza okuphakathi kwe-bit, futhi imbobo yokubhoboza inokuqondisa okuhle.Lolu hlobo lwebhithi lunomphumela omuhle wokukhipha impushana kanye nesivinini sokumba ngokushesha, futhi luyibhithi ye-DWB esetshenziswa kakhulu emakethe.
I-4, uhlobo lwesikhungo se-concave esijulile sobuso: lesi simo sebhithi sivela ohlotsheni olufanayo lwebhithi yezinyo lebhola, ingxenye emaphakathi yobuso bokuphela kwebhithi inengxenye ejulile yesikhungo se-concave.
Isetshenziselwa i-nucleation ohlelweni lokumba idwala.Lapho ubhoboza imbobo ejulile, ingaqinisekisa ukugcwala kwembobo yesibhamu.Ilungele kuphela ukubhola idwala elithambile kanye netshe eliqinile elimaphakathi.
