New tools have arrived after a bit of a cock up from the original supplier who was selling items they didn't have in stock and then couldn't get from the distributor. Ending up going through SGS Engineering and although I couldn't get the same package I was able spec up to the latest Get 3 drill and a braked angle grinder.
Like you do, I've spent the last few hours playing with the kit in the garage. Only been able to handle the tools in the shops before so not had the chance to test them properly. I'm more than impressed with their power and I'm sure some of my corded tools will become redundant now as these have just as much if not more power and control. The torque gun is dangerously powerful and can see that I will need to ensure the torque settings are correct before use otherwise it will easily strip the threads off of many fixings.
I started out with cheap power devil drills & they did the job for years. Where I worked they had metabo cordless that gave endless trouble with gearboxes then they switched to dewalt which were great.
I eventually invested in a Hitachi li-ion 18v drill/driver which has had serious abuse & is still going perfectly. I keep picking up spare hitachi drills (5), chargers (4) & batteries (6) so I have enough drills & spares to last years!
The only thing letting the Hitachi down is the price of extra batteries, even spurious ones are expensive!
More recently I bought a set of 24v blue bosch tools - a SDS drill, a jigsaw & a sawzall. They were used but well cared for & came with 2 batteries. I've been using them all & found them to be great. The most used item is the cordless jigsaw - I have a corded one that I rarely use but the cordless one is so much nicer to use. I was putting up some d-rail fencing & it was great for cutting the rails, no messing around with generators & leads! Then when it started to rain all I had to do was set the jigsaw into the boot.
The sawzall is useful too but seems to eat batteries, I'll have to invest in a 5ah battery for it. But that's the best thing about the 24v bosch, batteries are very cheap for it!
I know the OP has already bought Milwaukee but for any one else - check out the price of spare batteries before deciding what to buy. No matter how much you use it you will need to buy more batteries when the originals die. Dewalt & Bosch seem to be the cheapest batteries & are well catered for in the spurious battery market, Makita & Hitachi are expensive!
