Which tool must be used to drill a hole in masonry when installing a masonry fastener?

Using a hammer drill with an ANSI standard carbide bit is essential for drilling holes in masonry when installing masonry fasteners because it combines rotational movement with a hammering action. This dual function is necessary for penetrating tough materials such as concrete, brick, or stone, which are notoriously difficult to drill through. The hammer action helps break up the masonry while the rotation removes the debris, making the drilling process more efficient and effective.

Choosing a hammer drill specifically designed for masonry ensures that the tool can withstand the high impact and resist wear caused by the hard materials. The ANSI standard carbide bit is also integral because its design and material allow for enhanced durability and cutting efficiency in these tough surfaces, ensuring that holes are drilled cleanly and accurately.

Other drilling options, like an electric drill or a manual drill, may not provide enough power or the proper mechanism to effectively penetrate masonry. A rotary saw, on the other hand, is intended for cutting rather than drilling and would not be suitable for creating holes for masonry fasteners. Hence, the most appropriate and effective tool for the task is the hammer drill paired with a carbide bit.
