I'm in the market for a new jig saw, and naturally browsed the Internet to find the most popular, with good reviews on them. I shop amazon frequently, so naturally I got drawn here through Google links.
Reading the reviews here, and how this particular model wouldn't cut a perfect 45 degree angle I was disappointed, and began a hour long search for the previous model, the 1590 EVSK, which had been discontinued.
I had found a couple here and there that were factory refurbished, including one here on amazon. However those places that I had found that still had brand new model 1590s in stock, were raising prices way beyond the original cost of these, one found was as much as $325.00. Of course that was the extreme, but still others found were much more than the cost of JS470E shown on this page.
I couldn't believe that a company such as Bosch would manufacture a tool that had angle cutting capacity, and not be able to cut a 45-degree angle. Especially when there were no such complaints on the previous model.
So I called Bosch, first looking in their outlet stores for a refurbished 1590, explained what I had read in the reviews here, and got transferred to their tech support department.
I talked to a nice tech support representative and questioned him about this issue. He told me that they were aware of the reviews here on amazon, but that the JS470E 'will' cut a 45-degree angle.
He also mentioned that they have a tool free tech support telephone number right on the front page of all their tools, and all have a 30 day return policy. So I had to wonder why someone would spend the time to write a bad review on this product, instead of using that time to call their tech support department with this so-called issue.
I mentioned to them that they should post a review here with some information about cutting that 45-degree angle. Was told that they won't get involved in such matters, that they don't know who had posted such reviews, that it could have even been a competitor.
However when first hearing about this complaint, they did in fact pull one of these units off a shelf and test it to find out if cutting a 45-degree angle was in fact an issue with this model. I was told that they 'did not' find any issue with this model cutting a 45-degree angle.
I was told to feel secure in purchasing one of these despite these reviews and if I personally wasn't happy with the way it performed, to take advantage of their 30-day return policy.
After talking to them I felt a relief that I wasn't going to have to spend more money on their older discontinued model than what this newest model cost. Which by the way does have a better, larger motor in it.
I had also gained some additional knowledge in my conversation with tech support. One of the reasons I don't use a jig saw all that often is because of the blade flex, and getting a nice smooth, straight cut with these types of tools.
A common problem ever since these were first conceived... In my research I had found that most all larger manufactures lowered the blade guides to help with this issue, but still admitted that there will still be some blade flex when going through thick wood and other materials.
I was advised that first, use the shortest blade possible, as the longer the blade, the more flex you will have at the bottom of it. Also, to use high carbon type blades, as these would be much stiffer and not flex like standard type blades.
In reality, the blade flex isn't a factor of the tool, but in the blade itself. Something I discovered a long time ago. When this topic came up in my discussions, I asked why someone doesn't make blades to eliminate this, and that's when I was told to use the high carbon blades available on the market, and they will have more of a tendency to snap than to flex.
So all in all, a simple telephone call to the manufacturer, and I'm convinced that this newer model is the way to go, as opposed to overpaying for the previous discontinued model.
