Talandira ndemanga zabwino kuchokera kwa makasitomala athu pankhani yotsegulira dzenje la m'ngalande.

Chotsegulira mabowo a HDD chimachita bwino kwambiri popanga miyala yolimba ndi zabwino zake zazikulu. Kapangidwe kake kolimba, komwe nthawi zambiri kumakhala ndi tungsten carbide inserts, kumapereka kukana kwabwino kwambiri kwa kukwawa, kupirira kugayidwa mwamphamvu kuchokera ku miyala yolimba. Kutumiza kwamphamvu kwa torque kumatsimikizira kuti miyala imagawikana bwino, kuchepetsa nthawi yobowola. Kuwongolera kolondola kumasunga kukhazikika kwa njira ngakhale m'miyala yolimba, yosiyana, kuchepetsa kupotoka. Kuphatikiza apo, kapangidwe kake kosinthika kamagwirizana ndi mitundu yosiyanasiyana ya miyala yolimba, kuyambira granite mpaka quartzite. Kusakumba kumachepetsanso kusokonezeka kwa chilengedwe, zomwe zimapangitsa kuti ikhale yoyenera malo olimba omwe safuna kusokonezedwa kwambiri pamwamba.
