Ubujyakuzimu bw'icyuma cya TCT gifite uburebure bwa mm 50 gifite uburebure bwa mm 100 gikozwe mu gucukura hakoreshejwe icyuma cya weldon

Ubujyakuzimu bw'agace ka TCT (tungsten carbide drill) ka mm 50 k'ubujyakuzimu bufite icyuma gishyizwe ku ruhande gifite ibintu byinshi bituma gikoreshwa mu gucukura. Bimwe mu bintu by'ingenzi birimo:

1. Uduce two gucukura karubide ya Tungsten (TCT)

2. Igishushanyo mbonera cy'ubusa

Ubujyakuzimu bwo gukata bwa mm 50

4. Agatsinsino gafite icyuma gifata ku ruhande

5. Bikwiriye gukoreshwa mu gutobora hakoreshejwe magnetique
