    Buying myself a new combi-drill.

    I'm happy choosing the drill, just need some help with batteries.

    I will definately be going with 18v Li-Ion.

    The question is capacity and how many.

    I am an infrequent DIYer. Let's say I use a drill four times a year and then mostly for short durations.

    With the cheap Ni-Cad drills I have owned before I am used to the battery being flat when I come to use it, so work always starts with a charging session.

    This leads to my first question - in my situation is there any benefit to having two batteries.

    Next question 2.0A or 3.0A. Clearly the 3.0A will last longer and will be heavier. But what does that mean in real world terms. Also consider that whilst my jobs may be short they sometimes involve drilling into masonary.

    Cheers,

    Nigel

    First off I am a fan of the Hitachi drills, more affordable than Makita and Dewalt but just as good (in my humble opinion), I know you did not want this advice but I am going the extra mile.

    If you are that infrequent then the size of the battery is less important, however I would always advocate going for a 2 battery solution, even if you are infrequent user you could be in the situation where you are doing a lot of work during your infrequent uses to the point the one battery you have goes flat and then you have to wait for that battery to charge.

    As for battery type, Li-Ion battery ones I have retain their charge well and a 2 x 2.0A is probably more than good enough for your needs, again IMHO.

    That said you can pick up some good deals on NI-CAD drills, but they are a lot heavier than Li-Ion

    I have a Bosch 18v Combi, with 2X 1.3Ah batteries. They take 15-20 minutes to fully charge so despite the shorter run time, I'm never out.

    The run time is not stupid either.

    Depends on your budget. For about £170+VAT you can get a Milwaukee battery drill which is superb quality.

    I wouldn't buy Milwaukee, 2 of the joiners I work with both got the 18v impact and drill kit. Both sets have been back for repair countless times in the first year.

    They must have been unlucky there. I've got about 10 Milwaukee drills used constantly all during the day at work here and they don't give any problems at all.

    John makes a good point - a cheap corded drill maybe more useful and a hell of lot cheaper if all you are doing is drill holes, especially in brickwork.

    I third the motion for a corded drill.

    Splashing out on a combi drill and 2 batteries for use 4 times a year just is not worth it.

    The batteries on the cordless will probably be dead in a few years then you'll either be looking for expensive new batteries, or expensive new cordless and batteries again.

    The corded drill will be good for years to come.

    I just junked my old 14.v nimh drill bought a 10.8v lithium for £25. The pack is only 3 x 18650 cells in a easy to solder pack, the old one had 12 cells are tightly bundled together- a nightmare to de-solder and re-solder.

    Mains drill is a must when you're going into steel or masonry, they have far more torque.

    I thought we were drilling not soldering.

    Thanks, some varied advice there.

    For info, I am looking at a Bosch (blue - professional) that is about £100 with 3A battery.

    There is one with a slightly different number but it is the same drill with two 2.0A batteries for £150.

    However, you can get a 3.0A battery for £50 so the I can get the drill with two 3.0A batteries for £150.

    So same price for two 2.0A or two 3.0A. Seems a no-brainer but just checking that the 3.0A batteries don't make it heavy and unweildy.

    Or I can get it with just one 3.0A for £50 less.

    BTW - already have a corded drill - just want the additional freedom of being able to move around with the drill.

    Cheers,

    Nigel

    Have you links to the ones you're thinking about? I'm going through the same deliberations!

    A nephew of mine is a chippy and he reckons the 10.8V Bosch Professional range with the combi drill and an impact driver is the mutts nutts. (linky) The 10.8V is apparently shorter than the higher voltage drills and as such it will fit inside a 300mm kitchen cupboard to screw on the hinges and doors.

    I sell power tools.


    Always 2 bats if poss and 2.0 Ah is more than likely plenty for your usage for 18v.

    P.s. Check out Bosh Karat or Bosch multi constructor drill bits

    Hi,

    I went for this one in the end

    Bosch GSB 1800 18V 3Ah Li-Ion Cordless Combi Drill | Cordless Combi Drills | Screwfix.com

    with an extra battery pack

    Bosch 18V 3.0Ah Li-Ion Coolpack Battery | Batteries & Chargers | Screwfix.com

    So £150 in total.

    I did deliberate over this one in store.

    DeWalt DCD776D2-GB 18V 2.0Ah Li-Ion Cordless Combi Drill | Cordless Combi Drills | Screwfix.com

    It's a bit cheaper at £140 but has 2.0A batteries though I am sure that they would be more than I would need.


    Handled them both in the store - the Bosch felt smoother and better built. The Bosch is shorter, which is not a big deal to me but will be for some. The Bosch is more powerful on paper 67Nm versus 48Nm.

    I won't be using it for a few days so if anyone thinks I have made a bad choice please shout out because I can change it.

    Cheers,

    Nigel
