core drills
Hollow boring tools
Core drills are cylindrical cutting tools that remove a ring-shaped section of material, leaving a solid core intact.
Used in construction to cut through concrete, masonry, or asphalt for pipes and cables.
In geology, core drills extract cylindrical rock samples for analysis.
As an exercise, core drills are repetitive movements targeting abdominal muscles: We finished with five minutes of core drills.
