@Sideways do you have any experience with the Bosch GSR 12V - 15 drill, keep thinking of getting one simply for the right angle drilling ability and the offset head, not worried about the low capacity batteries but at only 10.8 volts can this drill deliver?
Hi.
I did buy the non interchangeable head version of the little 10.8v Bosch years ago - brushed. First impressions were very favourable and never left my bench for a good while.
In the end, I needed to rationalise and it's now parked at Deema's where we can grab it and use as screwdriver for our various team projects. We both love the tiny size but it comes at a price. The tool isn't as robust as I like. Plasticky chuck and you can certainly stall it. It feels more like a DIY series tool than a trade tool.
I settled on 18V everything. The tools are bigger and stronger but actually have better, slimmer handles because the batteries don't go up into the grip. That matters to me.
If you are doing electrical / plumbing/kitchen cabinet installation, then the small size of the Bosch does make a good argument. I think these multi head things are a great idea because of the 90 degree heads and the offsets. The current brushless 10.8V tools feel a lot better than my old one but are still tiny which is great. I'm almost tempted to have another go.
V useful review here. Notice the differences in size and power, also how the heads swap and index
I have owned and passed along a 12V Milwaukee brushed drill driver. Much bigger than the Bosch but smaller than their 18V tools, it has higher capacity batteries and stands up to serious use like extended sessions with a flap wheel or wire brush. That really impressed me both for build and for the power from a 12V system, but it has quite a fat grip.
Bosch and Milwaukee 10.8/ 12V tools (same thing, just defined differently) each have 3 cells in a triangle as they slot into the handle but they are oriented differently. One has two cells back, one forward, the other the opposite. They feel quite different in the hand because of it. The Milwaukee is more comfortable in bigger hands.
If I was a working tradesman, I'd probably want Milwaukee brushless for strong build, power and a big range. I understand why they are popular.
I use Bosch 18V brushless drill-driver, impact, the super smart cordless angle grinder, and the brushed circ saw (it was a freebie with the grinder) all with max 4Ah batteries. The ergonomics suit me and I think the 4Ah procore batteries are v good but the bigger tools need a bigger battery for max power.
