Attach the components of these sets onto a hammer drill to install tapping screws in concrete, block, and brick.

Also known as Tapcons, these screws are often used to anchor parts to concrete, block, and brick. Screws have a hex head that allows for a secure grip with a wrench. Drive them into a hole with a hammer drill or socket wrench, or use a specialized installation tool (sold separately). Made from ultra-corrosion-resistant coated steel, they resist corrosion in wet environments. Length is measured from under the head.

Each bit is precisely sized to match the tolerances necessary to achieve maximum holding strength from tapping screws. Use with handheld power drills, drill presses, and hammer drills. The shank has a tang which allows it to fit into a drill press with a tapered spindle.

Each bit is precisely sized to match the tolerances necessary to achieve maximum holding strength from tapping screws. The SDS-Plus shank has two deep slots and two shallow slots for use with SDS-Plus-drive rotary hammers. These bits cannot be used with SDS-Max-drive rotary hammers.

Insert these bits directly into power screwdrivers, impact drivers, and other tools that accept 1/4" hex shanks. Each is precisely sized to match the tolerances necessary to achieve maximum holding strength from tapping screws. They have a built-in hex collar that acts as a stop for repeatable drilling depths. The split point keeps the bit centered without a pilot hole.

A drive sleeve (sold separately) slides over the drill bit to drive fasteners without removing the drill bit from the tool. One end engages with the hex-collar on the drill bit, while the other end holds a screwdriver bit.
