How to safely remove the drill bit from a concrete or masonry hole

When drilling holes in concretes, you may need masonry core bits. The drilling machines you will use depend on the type of concrete core bits. You may find some drill bits like a rounded that are used for hammering type drills. The standard drilling machines may use a regular tip concrete core bits.(You may see Why should you choose Diamond Core Bits in drilling?) Sometimes, Failure that may result breakage in the bit is because of not continuing or fail to exit the drill bit to the concrete materials. Here are my tips on how to safely remove the drill bit when unexpected case happen like drill bit breakage or something.

You may need the following: Canned air, Vise grips and Needle-nose pliers.

1 - Blow air straight into the hole with the canned air. This will loosen and remove some of the concrete dust around the drill core bit.

2 - Lock the jaws of a pair of vise grips around the end of the bit, if the bit broke off above the surface. Clutch the bit as close to the work surface as possible. Drag out the drill core bit while turning the bit counterclockwise with the vise grips. Blow air into the hole as necessary if the bit jams while removing it from the concrete.(see A must have Drilling Guide Kit)

3 - Insert the jaw tips of a pair of needle-nose pliers into the hole, if the bit broke below the work surface. Try to grasp the end of the bit with the needle-nose pliers. If the needle-nose pliers cannot reach the bit, make the hole slightly larger with another drill bit. Drill just until you reach the broken bit.

4 - Blow the hole out with the canned air. Grip the end of the drill bit with the needle-nose pliers. Pull and wind counterclockwise with the pliers to remove the bit from the hole.
