Best Drill Bits For Granite FAQs
Can regular drill bits be used to drill into granite?
Regular drill bits are not suitable for drilling into granite because granite is a very hard and dense rock. It requires a specialized drill bit that is designed to cut through hard materials like stone, concrete, and masonry.
