Drilling bit tools
Drill bits are tools used for drilling holes with core extraction. Depending on the type of core barrel, we distinguish single crowns (used in single core barrels), double crowns (used in double core barrels) and triple crowns (used in double core barrels with an additional protective tube for the core).
