Drill Anchor Holes in Concrete
From Install Outdoor Handrail · Step 4 of 8 · Video by Family DIY tv
Showing 2:13–3:24 of the source video.
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.
