AT Hole Enlarging Core Drills
Alfa Tools Hole Enlarging Core Drills—also known as shell drills or core reamers—are precision high-speed steel (HSS) cutting tools engineered to enlarge existing holes with exceptional accuracy and efficiency. Designed with a multi-flute cutting geometry and hollow center, these tools remove only the material required to increase the hole diameter, making them an ideal solution for enlarging pre-drilled, punched, cored, or cast holes.
