Dant wedi'i falu Darnau Dril Roc Tricone:
Y dant wedi'i falu (dant dur) tricone darnau drilio ar gyfer ffurfio creigiau meddal i ganolig.
Defnyddir y darnau tricone dannedd wedi'u melino sy'n ffurfio meddal i ddrilio cryfder cywasgol isel, ffurfiad meddal.Defnyddir hyd dannedd rhagamcanu hir ar gonau gwrthbwyso uchel i ddarparu'r cyfraddau treiddiad mwyaf posibl.Defnyddir ymwrthedd gwisgo wyneb caled i reoli traul dannedd.Ar y mathau didau meddalaf mae'r wyneb caled hwn yn gorchuddio'r dannedd did yn llwyr.
Defnyddir y darnau tricone dannedd melino ffurf canolig i ddrilio cryfder cywasgol uchel, ffurfio creigiau canolig.Defnyddir dannedd taflunio saethu gyda hyd crib llai yn y gyfres hon o ddyluniadau didau.Defnyddir wyneb caled gwydn i leihau traul dannedd.
