Rhagymadrodd
Mae'r Darnau Drilio Creigiau wedi'u gwneud o aloi caled gradd a dur arbennig, wedi'u paru'n gyffredinol â'r dril roc ysgafn, i
drilio twll y graig o fewn diamedr o 50mm.Defnyddir yr offer dril mewn mwynglawdd meteleg, archwilio daearegol, dŵr
adeiladu cadwraeth, trydan, traffig, twnnel, chwarel, prosiect carreg amddiffyn cenedlaethol ac ati.
