Hi, I've just got a new makita combo drill. I am trying to put up a bracket for a garden hose onto brick pillars at my garage. I've charged the battery and put in a 7mm masonry bit in the drill at the hammer drill setting. It has taken about ten/fifteen mins to drill about 10mm into the brick. I need to drill 50mm, at that rate I'll be at it all day. What's gone wrong? I have a feeling the bits supplied are cheap ones, could that be the problem? According to the instructions mounting the hose reel, I should use tungsten carbide tipped bits. I haven't the faintest idea about diy so I have no experience of this kind of thing but I bought a drill that is supposedly capable of brick, concrete drilling etc. Any ideas please?
