Shoot nails into concrete
If you have a lot of concrete fastening to do, consider a powder-actuated tool. It uses a gunpowder load to shoot a special nail into concrete. It’s the quickest masonry fastener available and costs as little as $25. Be aware that use of these tools is regulated in Australia and you require a licence and have to undergo training.
Control the dust
Concrete contains crystalline silica, which can lead to serious health issues. Always wear a respirator when drilling into concrete, but don’t stop there. A vacuum nozzle close to the action prevents most of the dust from ever going into the air.
If you hit a hard spot, move on
When you’re drilling concrete, sometimes you’ll hit something that the bit can’t easily penetrate, typically a rock or rebar. Sometimes you can work through it, but it’s best to try a different spot. Even if you get through it, your fastener will hit it too and likely shear off as you’re driving it.
