• How long should it take to drill a 10cm deep hole in concrete, with a 16mm SDS Plus drill bit? The drill has 850 watts of power, plugged into usual 220v three pin socket. Doesn't feel like it's making much progress

  • Don't want to teach you to suck eggs, apologies if this is super obvious, but I have seen people drilling away at something for absolutely ages with the drill in reverse gear...

    Edit: although whether it makes a huge difference when smashing in to concrete with an SDS I don't know...
