Drill Anchor Holes in Concrete

What happens in this clip

Using a hammer drill with a 3/8-inch SDS bit, drill the four marked holes into the concrete. To ensure correct depth, wrap tape around the drill bit a quarter-inch (0.25 inches) further than the length of the wedge anchor. This allows space for the anchor to expand. While drilling, use a vacuum cleaner nozzle near the drill bit to immediately suck up concrete dust, which helps keep the holes clean and clear. Once drilled, remove the tape and thoroughly clean out any remaining debris from the holes using the vacuum.

Goal: Create precise and clean holes for the wedge anchors in the concrete.

Step 4 of 8: Drill Pilot Holes in Concrete

Select a masonry drill bit that matches the diameter specified for your chosen concrete anchors. Use a hammer drill for efficient drilling into the concrete. Drill to the depth recommended by the anchor manufacturer, ensuring the holes are perpendicular to the surface for a secure fit.
