Chinovhura maburi cheHDD chinobudirira mukugadzirwa kwematombo akaomarara chine mabhenefiti makuru. Dhizaini yacho yakasimba, inowanzoiswa tungsten carbide inserts, inopa kudzivirira kukuru kwekukwesha, inogara ichikuya zvakanyanya kubva pamatombo akaomarara. Kutumirwa kwesimba rakawanda kunoita kuti matombo apwanyike zvakanaka, zvichideredza nguva yekuboorera. Kudzora kwakarurama kwenzira kunochengetedza kugadzikana kwenzira kunyangwe mumatombo akaomarara, akasiyana-siyana, zvichideredza kutsauka. Pamusoro pezvo, chimiro chayo chinochinjika chinokodzera mhando dzakasiyana dzematombo akaomarara, kubva kugranite kusvika kuquartzite. Kusachera kunowedzera kuderedza kukanganiswa kwezvakatipoteredza, zvichiita kuti ive yakakodzera nzvimbo dzematombo akaomarara dzisingade kukanganiswa zvakanyanya pamusoro.
