FAQ's: Percussion Core Drills

A core drill removes only the outer ring of the hole, leaving a solid core inside, while a regular drill removes all material from the hole.

It uses a hollow, heavy-duty bit with a diamond or carbide edge, combined with hammering action, to grind and chip away material around the hole perimeter.

They’re ideal for concrete, brick, block, and stone. With the right bit, they can handle reinforced concrete as well.

A percussion core drill uses hammering action combined with rotation to cut large holes in masonry, concrete, or stone by removing a cylindrical core of material.
