Bosch GSA18V-125 18V EC Brushless 1-1/4 In Stroke Multi-Grip Reciprocating Saw REVIEW

On this overview we shall be looking at Bosch’s newest cordless reciprocating noticed, the Bosch GSA18V-125 18V EC Brushless 1-1/4 In Stroke Multi-Grip Reciprocating Noticed and can talk about it’s function set and efficiency.


Bosch was form sufficient to supply the Bosch GSA18V-125 18V EC Brushless 1-1/4 In Stroke Multi-Grip Reciprocating Noticed for free of charge for overview. Nevertheless as with all my critiques, I’m not paid, sponsored, or obligated to provide a constructive overview. This overview is my opinion of the product based mostly on my utilization and information and my overview will mirror what I like and dislike in regards to the product. I’ll do my greatest to offer you an unbiased overview.


After I first heard of this new Bosch 18V brushless reciprocating noticed I used to be impressed by its specs checklist for a cordless noticed mannequin with not solely a brushless motor for higher runtime and energy but it surely has some specs you’d discover on corded recip noticed fashions such because it’s massive 1-1/4″ stroke size. This implies this noticed cuts extra per move. It additionally has an orbital mode with two orbital settings selectable through a prime mounted dial. Most cordless recip saws supply solely straight inline reducing motion but it surely’s all the time a pleasant function to have orbital reducing as an possibility to have the ability to reduce sooner resulting from a extra aggressive orbital reducing motion. The orbital mode on this noticed helps you to select between orbital mode one and two with two being full orbital mode and mode one being a lessor aggressive orbital mode. I discovered this noticed to be a full featured reciprocating noticed because it provides not only a variable pace set off however it’s also possible to dial down the max RPM with a separate variable pace dial to additional management reducing pace.

The checklist of options doesn’t finish there as they add a rafter hood on the correct facet that folds out and might cling it inside arms attain and folds again flat when not in use. That is actually helpful so you may cling it close by when your working so that you don’t must relaxation it on the ground and choose up every time when wanted. Being a contemporary instrument, they’ve added an LED mild on the entrance of the instrument simply behind the shoe so it illuminates the reducing path which is beneficial while you’re in low mild. To verify Bosch packed in as a lot options as they may they added a pivoting adjustable size shoe. Simply press the purple button beneath close to the shoe which disengages the shoe so you may slide it ahead or again for the specified size. That is helpful for transferring the shoe ahead to squeeze as a lot life doable out of your blades and utilizing the unused portion of your blades.


Since we’re speaking in regards to the shoe, my copy of the instrument had a really stiff pivoting shoe which makes it onerous to get a superb agency flat contact with the fabric being reduce when beginning a reduce. I emailed Bosch about this and so they stated that it will loosen up over time with use. I used it a good quantity and effectively over 100 cuts later and it’s nonetheless stiff as day one, bummer.


One in all my favourite options of this reciprocating noticed is the blade change lever which is a big simple to grip steel part on the entrance of the instrument simply behind the shoe. It’s very simple to achieve and rotate to exchange blades with or with out gloves.

Total the match and end of this noticed is prime notch, particularly the graceful rubber overmold they use on the entrance finish. The ergonomics are excellent as effectively and due to the slight angle of the best way they mounted the motor signifies that it has a greater middle of gravity than different reciprocating saws. Certain it’s nonetheless entrance heavy as all reciprocating saws are however not as entrance heavy as others making it a bit extra balanced to carry.


Not like different reciprocating saws, Bosch determined to ditch the norm and cast off a lock and unlock swap that may lock the set off from being activated. You may consider this as a passive security function if the consumer decides to make use of it or not. Bosch as a substitute opted for a security swap constructed into the set off that’s just like the one’s used on angle grinders with paddle switches. Because of this you need to slide ahead/push the protection in every time you use the set off in any other case it wont have interaction.


Pricing of this noticed as a baretool is extraordinarily excessive as a baretool at $299 ( GSA18V-125N ) nevertheless Bosch provides this noticed as a equipment for $399 ( GSA18V-125k14 ) that comes with their newest Core 6.3 ah battery, charger and onerous case which makes it a greater worth. Should you’re planning on including this noticed to your assortment, it is sensible to go along with the equipment because it provides a a lot better worth. Nevertheless in comparison with it’s competitors it’s about $100 greater than it’s friends whether or not you’re trying on the baretool or as a equipment.


Bosch added some very attention-grabbing anti-vibration options on this reciprocating noticed with a really efficient counterbalance system inside. It’s very efficient when there isn’t a load and the motor is working. Should you press the set off and run the motor when not making a reduce, that is simply the smoothest working, least vibrating reciprocating noticed I’ve ever tried. However that each one adjustments while you truly make a reduce and issues flip the other and when it’s truly reducing. It’s one of many worst I’ve tried with regards to vibration. I’d say the vibration isn’t coming from the instrument itself however as a substitute from the extraordinarily aggressive reduce it produces. My guess is that this might be because of the considerably decrease 2500 max RPM’s which may trigger the shortage of easy cuts plus such a big reducing stroke. However in my expertise with this instrument, it rattles my arms to the bone and previous the elbow, yikes! However all reciprocating saws vibrate and are one of many worst offenders within the instrument world.

Whereas the reducing efficiency is harsh in your arms, this reciprocating noticed has nice reducing efficiency as it might probably reduce 2×4’s and 4×4’s very quickly. Watch the above video to see this dangerous boy in motion. It’s additionally a stable performer at steel reducing when geared up with a steel reducing blade. Although it’s a cordless battery powered instrument, it performs like a corded reciprocating noticed.


I in contrast this noticed facet by facet at reducing 2×4’s and 4×4’s and with regards to reducing lumber it outperforms Milwaukee’s M18 Sawzall which is one other cordless mannequin that performs reasonably effectively. It additionally outperforms the cordless Milwaukee mannequin at steel reducing which was already sooner than others I attempted on the time.

I additionally added the Milwaukee M18 Gas Tremendous Sawzall to the comparability to see the place the Bosch cordless brushless mannequin sits and it retains up effectively towards the tremendous sawzall mannequin by way of efficiency sitting simply behind it within the lumber reducing 2×4 and 4×4 assessments. Nevertheless with regards to steel reducing, the Bosch mannequin stands equally toe to toe with Milwuakee’s newest cordless flagship mannequin because it supplied the identical pace of reduce when reducing the structural pipe. If something the Bosch beat the Tremendous Sawzall at steel reducing by a hair because it received by a millisecond!

As you may see in each of the above movies, I featured facet by facet clips of the Bosch recip noticed in all of it’s reducing modes from inline to orbital 1 and a couple of. As anticipated, the orbital modes supplied a faster fee of reduce when it got here to the two×4 cuts with orbital 1 reducing sooner than inline and orbital 2 reducing the quickest out of the three. The distinction was very noticeable between all three modes when reducing 2×4’s.

Nevertheless when reducing a 4×4, issues modified. Orbital modes did supply a sooner fee of reduce in comparison with inline, however the distinction was negligible and was very onerous to note except you set the video clips facet by facet and even then was virtually the identical, simply barely sooner when in orbital modes. Additionally needed to say that orbital mode 1 & 2 reduce about the identical pace when reducing a 4×4 which makes me surprise that the orbital motion isn’t very efficient with thicker supplies.

145 cuts (2×4)

Bosch provided one in every of their latest Core 18V 6.3ah battery for testing this noticed and I used to be capable of get a complete of 145 cuts into 2×4. This has been probably the most cuts per cost of all of the cordless reciprocating saws up thus far, nevertheless that’s additionally partly as a result of this has the most important amp hour battery I’ve tried on 18V recip saws. After I examined the Milwaukee M18 Sawzall (brushed motor 2621-20) mannequin, it achieved 110 cuts into 2×4 with a 3.0 ah battery. That signifies that the Milwaukee noticed achieved 36.6 cuts per amp hour. This Bosch however will get 24.16 cuts per amp hour which means it chugs extra battery juice per reduce. My guess is that that is because of the extra highly effective motor it makes use of for extra efficiency and as everyone knows, extra efficiency equals extra gas consumption. As one other comparability, the Ridgid GenX5 brushed motor reciprocating noticed obtained 89.5 cuts with a 4.0ah battery which is 22.37 cuts per amp hour. Because of this the Bosch nonetheless is healthier by way of runtime than the Ridgid however not by a lot. Contemplating this can be a brushless instrument, I’d assume it’s runtime might be higher.

Bosch’s newest brushless 18 volt reciprocating noticed packs in nearly each function doable and provides a really good package deal from match and end to it’s incredible function set which incorporates two orbital modes, rafter hook, the very best blade change lever and variable pace dial on prime of it’s variable pace set off. It’s reducing pace makes it one of many higher cordless fashions with quick reducing motion and corded noticed like efficiency. Though it contains a brushless motor, it’s runtime effectivity might be higher. It options anti-vibration know-how nevertheless it’s solely helpful it’s not reducing as reducing something makes for a really bumpy journey. Bosch spared no expense with this instrument and it additionally reveals up in it’s greater than common worth level.
