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 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.

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.

Good for high-volume cutting and trimming.

Handles have a safety lever that prevents accidental operation; push the thumb latch forward to activate.

Jaws can be mounted in the handle for left- or right-hand use.

Style D jaws allow precise cutting from above. Pointed-cut jaws cut and crimp in one action.

Cut profile refers to the amount of pinch left on the tip of the wire after it has been cut. Pointed cutters produce a deeply pointed, pinched end. Use for electrical and general applications. Semiflush cutters are the most widely used for electronics assembly and produce a slightly pointed, pinched end. They are generally more accurate than pointed-cut tools. Flush cutters produce a cut with virtually no pinch, creating clean connections for easy soldering. Flush-cut tools don’t last as long as pointed and semiflush.
