If you're not sure whats the difference between the "Brushed" and the "Brushless" Version of the two screwdrivers, this should give you an better idea. #Bosch #cordless #12v #boschprofessional #boschtools #tools #comparison #review
I have had the old 10.8V one, for 16 years, it is Wurth branded though. Today it have started misbehaving, I will open it and see if I can fix it, but I think it may be time for a new. It has been an incredibly good tool, I have never really "abused" it, but have used it more or less everyday for 16 years, mostly small screws out/in. In the winter snow and salt water have ran into it even, zero problems. Even the batteries are 16 years old and very good, not as new, but good.
If you have a chance to compare drilling performance of both that would be great. I have a 12v-15 and can drill even concrete with thin drill (such as 5 mm diameter). Brick walls are also easy to drill. I guess the performance of 12v-35. For small operations, hammer drill may not be necessary
Is it easier to regulate the brushless version in gear 1? I notice you had it in gear 2 which you isn't the best mode for slow and precise driving of screws.
The brushed version is finer and easier to regulate of the two versions in general, especially in lower rpm. The brushless is a bit harsher, but it is true that in 1st gear its easier to regulate then in 2nd gear.
@@speedplanet Good to know thanks. The regulation is definitely important to me, but how much nicer a tool is the brushless version over the brushed to use in everyday tasks (ignoring power and battery life) ?
The GSR 120Li compared to the 12V 15: + 1500/min (12V 15 =1300/min.) - no charge level indicator - no fast charger Handle is 1cm longer Design minimally different Suitcase smaller
I have the 15... im having an issue with drywall montage - it is difficult to screw drywall to Knauf profiles. So, im thinking of upgrading to 35 - do you think it will be good enough?
As the soft torque of the 12-35 is 5NM more then the 12-15 this could make a difference. Other then that I would recommend at least the 12V 2.0Ah batteries to have enough power. I just took both machines to the test with an 2Ah battery and screwed a Knauf screw just right to an 6mm sheet metal without any problem even with the 12-15 in 1st gear. As any case can be a bit different, to answer your question is of course without guarantee. Hope this points you to the right direction.
First gear and second gear is a speed issue actually. It's not increasing torque with increasing gear indeed. I use second gear for polishing and similar works. First gear is suitable for metal drilling or screwing.
