    Hey Guys,

    I'm after a decent core drill for drilling mainly stone and brick for boiler flues where the clutch won't keep packing in (like on my old Makita). What do you recommend?
    I've been looking at the Marcrist DDM2, anyone got any experience with them?

    You gas safe, don't think you can drill the hole, you can stand and watch a Gas Safe engineer do it... needs to be falling the right way. +- 0.346 of a degree

    Yes I am Gas Safe. Not sure how I go about showing it on these forums!

    A shame, it looks a good bit of kit. Like I say I've been using a makita but the clutch has gone on it a few times now so i've lost faith in it. Any recommendations on any other drills if thats discontinued?

    Over the years ive gone for cheap drill when broken chuck away. Ive given up trying to win this situation as to either spend a lot for a good drill or buy cheap and have it break quicker

    DDM don't have a chuck, just a thread to screw cores on.
