The Bosch GSA18V-083B 18V Reciprocating Saw is built to easily move through difficult tasks in tight spaces that other recip saws can’t fit. It has the best power-to-weight ratio in its class, and delivers a fast 3,050 strokes per minute. At only 15-3/4 In. long and 4.4 Lbs. (bare tool), this powerful, compact cordless recip saw provides an impressive 0.83 In. stroke. This allows electricians or plumbers to remove more material per stroke. The tool’s light weight is ideal for continuous cutting in over-the-head applications. The easy-to-operate blade-change system allows for fast toolless blade changes, and its LED light helps to illuminate the cutting zone. This tool comes with a lock-out switch, to prevent inadvertent startup of the tool, for added user security. The GSA18V-083B is a bare tool; the battery and charger are sold separately.

Mr. Bill –
Updated review – Big changes!
Yes I originally gave this tool one star. You can read my original review, below. So what’s changed?Well, I now have a lot more experience with the saw, and understand that it all depends on how you plan to be using it.Bosch makes 3 different cordless recips and I have the luxury of owning all three (see attached pic). I use all three regularly, for very different purposes.The 12V is terrific for light duty trimming, landscaping, etc. – very lightweight and portable.The 18V “conventional” is hands down the best for demolition or other construction work. If you will own only one 18 / 20V max (which are both the same thing) cordless recip I feel strongly this is the one to own.However, this 18V “compact” saw is used a lot in the course of my volunteer work at state parks. I use it for trail maintenance and also for the removal of invasive and harmful species. The lighter weight and somewhat smaller size is a real advantage when walking for miles through the woods!In conclusion, this is a really great saw. Whether it’s the best saw for you depends on what you need done.ORIGINAL REVIEWYeah, I am a Bosch fan. So why 1 star?It’s because you definitely don’t need this.If you are doing real demolition work, get the “regular ” saw, it’s a lot better. If you need smaller, are space confined, get the 12v version. It is better for that job.This saw is not bad tool, in fact far from it. The cutting speed and power are everything I had expected. However, its size and weight were definitely not. It fills a tiny niche, at best.

Excellent tool where portability is most important not cutting capacity
Where portability is important this is the right tool for the smaller jobs. We have a number of Bosch tools so batteries of different sizes and charging stations are already in use, so this bare tool works well for us. For large heavy-duty applications we still prefer corded tools but to take up a ladder to trim something, or to clean up a bush or tree the BOSCH GSA18V-083B 18V Cordless Reciprocating Saw is the better choice. Stock blades fit but we suggest you do not overload with a full-size blade. This little saw works great with a higher stroke rate of 3,050 SPM than our corded RS325 Professional which has 2,800 SPM but at 12 Amps and a stroke length of 1″ verses 0.83″ it has significantly more power and runs as long as you want on 120 volts. We can recommend both but if you only want one, we suggest the corded model it is bigger, heavier, and surprisingly less expensive at $100. So, as they say more bang for the bucks.

Light and fast
Iâm a homeowner, not a professional. It took about an hour to fill my pickup with branches and tree limbs, and the battery still had 2/3 lights. The saw cuts so much faster than my 20 year old Milwaukee sawzall, that I just used the Bosch. 1-5 seconds and done. One-handed cutting on top of a step ladder is a life saver. I no longer dread spring or storm cleanup. Best tool upgrade for homeowners.Make an excuse to get one. Fatherâs Day? Birthday? Tuesday?

Works great after Bosch fixed initial problem.
**Update 4/26/2018** Contrary to Derf’s comment below, it was most definitely an issue with the tool. Have finally had a chance to use this saw some more after Bosch replaced the electronic module. The saw now cuts great, without any of the issues it was having before. It cuts just fine though large boards (up to 4×4 so far), as well as nails, screws, and larger bolts (with appropriate blade). Have also cut all of the same materials with the different size batteries (1.5ah slim, 2ah slim, 6.3ah core) and all worked fine. I am updating review to 4 stars since Bosch has seemed to fix the issue.**Update 2/15/2018** I ended up sending the saw in to a Bosch service center, when it was returned (2/14/2018) it noted they had replaced the electronic module so hopefully that was the issue. I haven’t had a chance to try it yet, but am bumping up to 3* for now due to customer service. If it does perform fine here on out I will come back and update again.**Original Review**I purchased this August 2016, and have only used it a few times since. This saw is seriously under powered. It is great on PVC, It is OK when used on small branches (1″ or less), and usually ok on 2×4’s, though I have had it stall/stop on a couple boards. Where this saw really falls short is if you need to cut through nails. Using the appropriate metal blade it stalls about 4 times cutting through a single 16 penny nail, which is very disapointing. I love the size and weight, but the saw seriously under performs for it’s price.

No problems here
After 3 years, this is still holding up. To be expected for the brand!

Very nice saw.
I wanted a battery powered saw to use instead of my older 120V saw. I also wanted a saw that would use the existing batteries I have that power my drill motors. This saw is lighter than my older saw and very easy to hold and use! I’ve used it to cut both metal and wood with no issues and seems to work as well at cutting as the 120V saw. I also like the easy blade change collar!

I have the full size Bosch saw but prefer this one because it’s much lighter and easier to be manoeuvred around in tight corners, and the battery lasts a long time

This is a great compact saw. Has plenty of power, and good for working in tight spaces, and well balanced.I used this for cutting up palm tree branches, and it was excellent. I can use this saw one handed which is a huge plus for me. As a product to give you an idea this saw fits in between a lopper and a chainsaw. I can cut branches directly into my green waste bin or to prepare cuts for my wood chipper. Overall so far so good very impressed with this tool, its saved me a lot of time, and effort making cutting jobs easy.
