You happened to stumble into the deals section. I'd stick to asking non-deal questions to the
Milwaukee tool thread, as you should get better responses there. But too be quick, the new M12 HO are not as much of an improvement over the existing options as M18 HO did. No M12 tool was specifically designed for the HO batteries, so while maybe it bogs down a bit less under the right circumstances with the new battery, I'll be more than fine with 6ah at a better ah per dollar pricing.
The biggest improvement is the shell to the battery if anything, providing better protection & a tighter fit.
I'd say the new HO don't provide much for increased power, but rather prevent any power drops/sags. So far my use with them is in the Multi-tool, Cut-off tool, impact wrench, and inflator. No noticeable difference on any of them for me, but 9/10 times I'm using a 6ah on the tool already.
please post any replies or further questions that are tool related, rather than deal related, in the other thread. With the deal season upon us, it helps others just see what they are hoping to see in this thread (deals!)
