This battery works just fine. In fact, it's the type of battery I used for it's first round of use. The problem isn't the power, it's the charge life of the smaller batteries. You're not going to get much of use with a single battery, maybe 10 minutes of straight use, before it dies. Highly recommend the XC series batteries, though the smaller ones worked just fine for me.

Answer: 
Well, it can be done. but you need a sharp blade and a lot of patience. Take it slow and don't bind the blade. It might be easier, especially on a straight cut, to use a circular saw with a clamped guide. just a thought. :)

Answer: 
Yes, the M18 Jig Saw (2645) will easily cut through 3/4” OSB. A few things will effect speed.
1. Orbital Action or Straight Cutting: The saw has an adjustment for orbital or straight cut. Orbital will cut wood faster but will leave a rough finish.
2. Blade Choice: A high tooth count blade will leave a cleaner cut but slow down the saw. A low tooth count blade will cut faster but leave a rough cut.

LED-light?

I see an older question regarding work-light on this jigsaw with a negative answer, from "Milwaukee electronics". Milwaukee states on their own site that this saw comes with a Led-light. Is the old information above still valid?

Rated 3.8 out of 5 by 56 reviewers.
Rated 4.0 out of 5.0 by Cuts like butter Heavier than competitor, but that is a sign of quality guts and it did help absorb vibration well. Cut like butter with Bosch blades. Variable speed is great. I do wish there was blower and a light. I ended up taking off the splinter guard and the plastic guard around the blade and blowing with my mouth often so so I could see the cut. September 20, 2016
Rated 5.0 out of 5.0 by Awesome piece of equipment! Ive had many pieces of cordless equipment from many different manufacturers. The technology just keeps getting better and better and nobody does it better than Milwaukee!!! September 13, 2016
Rated 5.0 out of 5.0 by Great jig Quality tool. I will agree with other comments it is a bit heavy, but it is sturdy. July 19, 2016
Rated 5.0 out of 5.0 by Worth the extra money! The saw is just well designed and is a great tool. I am not a professional but I decided to try the Milwaukee brand and was not disappointed. June 14, 2016
Rated 5.0 out of 5.0 by beast of a jigsaw i am a professional carpenter and use this jigsaw all the time from light framing to fine trim work. when the jigsaw is paired with a 5.0ah battery i can use it for days. once you get used to the weight of the saw you can use it for things as delicate as coping cuts. September 20, 2016
Rated 3.0 out of 5.0 by Broke on second cut Brand new, second test cut, torqued the blade a little and the guide shifted sideways permanently and orbital action lever no longer has an effect. I'm usually happy with milwaukee tools so I'm going to count this as a fluke unless it happens again, but very disappointed as this shouldn't really be a fragile tool. Not happy about that as I needed it for a job today. Taking it to a service center first thing Monday. Assuming that was a fluke, besides that a theoretically excellent jigsaw. I expect solid battery life like all the other M18 tools. Has all the right useful adjustments, easy to set. Wish it had a light though. October 11, 2015
Rated 5.0 out of 5.0 by Really good. It was bigger and heavier than I thought it would be. Very stable and powerful. I'm happy! I switched to Milwaukee tools a couple of years ago and it has turned out to be a great choice. February 14, 2016
Rated 4.0 out of 5.0 by Good Product, Poor Retailing Practice This saw works so much better than the several cheaper corded ones I have owned. The base is stable and doesn't need constant adjustment and it has plenty of power. The biggest problem I have with this purchase is that it was on the shelf in a closed box in the store but when I got it home I found it had been used and returned to the shelf. There were no protective packaging in the box and no instructions- just the saw. I consider this to be very poor practice by Home Depot and will surely be checking my selections for purchase carefully before I buy from now on. I kept it this time because there is nothing wrong with the saw, it was th e last one on the shelf, and I needed one for immediate use. November 3, 2015
