Imyitozo ya Hollow izwi kandi nka bits ya drill bits, gufungura umwobo, hagati ya drill bits, ibyuma byerekana ibyuma, ibyuma bya magneti, bits ya gari ya moshi, nibindi.
Ibikoresho byingenzi byimyitozo ni: ibyuma byihuta;ifu ya metallurgie;Carbide.
Imyitozo ya hollow ifite ubwoko bwuzuye bwubwoko nibisobanuro kandi birakwiriye kubirango bitandukanye byimyitozo ya magnetiki itumizwa mu mahanga (imyitozo ya magnetique) hamwe nimashini rusange yo gucukura, imashini zisya, imashini zirambirana, nibindi. Iki gicuruzwa gikoreshwa hamwe na magnetiki yatumijwe hanze. umwitozo, kandi imikorere yo gucukura irikubye inshuro 8 kugeza ku 10 iy'imyitozo isanzwe.
