Core Application: Primarily used for drilling through abrasive materials like concrete, reinforced concrete, asphalt, soft brick, masonry block, rock, and stone. Cutting Mechanism: They function via a scraping action rather than a tearing action, ensuring high-speed drilling and clean entry/exit profiles. Wet vs. Dry Options: Depending on the material, they are designed either for wet use (utilizing continuous water flow to cool the bit and suppress dust) or dry use (utilizing ventilation slots or thin kerf designs).
