how to drill into concrete

Drilling into concrete is tough because concrete is solid, hard, and has installed aggregate stones that can be obstacles to the drill bit. Drilling can instantly dull drill bits. When the bit encounters aggregate, the bit drags even more. The selected tool for drilling into it is a hammer drill.

How to drill into concrete without a hammer drill?

A hammer drill is separate from an ordinary rotary drill. Like a rotary drill, the hammer drill rotates. Unlike a rotary drill, it hammers while it rotates. Hammering helps to grind the concrete, while the rotation creates the hole.

1- Mark the centre of the hole on the concrete, and insert a small-sized masonry drill bit in your drills chuck. Begin drilling into the concrete applying steady pressure on the drill. If any time you feel the drill bogging down back off some.

2- Gradually increase the size of the masonry drill bit until you hit the diameter you’re looking for. Increase the size of the drill bit by no more than 1/8 of an inch at a time and re-drill the hole.
