Poorly designed product. Avoid.
I called Bosch customer support when my PEX 270A had the problem of throwing pads. They were not very helpful and suggested I contact customer support via email, so I wrote them the following email:
My PEX 270A orbital sander will not keep sanding discs adhered to the velcro. After a little bit of research I discovered that this is a common problem with this series of Bosch sanders which implies improper design of the material that is used to keep the discs in place.
I refer you to the following 2 sites for reference.
Older Swiss made was a solid machine
Very good machine, but with a disclaimer: I purchased mine a number of years back and it was made in Switzerland, and I have no clue what their quality is like now, so my advice might only be applicable to second hand. But it's a great machine. I've even done absurd things like polish a full terrazzo floor with it. The dust extraction isn't the greatest, and it has chucked a disc once (ever) - after I put it on not realizing it was caked in dust.
The problem with this particular sander is now over. I have spent 7 days drywall sanding with this model. Other than small for the job i am doing, the PEX 400 is brilliant and not once as the disc come off. My main problem is that the vacuum cannot keep up with the sander
This machine is fabulous for the first year. Then the sandpaper discs start throwing off.. so I get a new disc attachment as the surface has gone too smooth and wont hold the sandpapers on. Carry on.. then it happens again..so buy a new disc attatchment.. Carry on.. and the whole disc attatchment starts throwing off. So I buy a new disc attatchment. It throws off as soon as its put on.. then find out that the thread is bare on the centre screw. Another $150 to fix all up apparently..so now have to buy a new sander..All this from a sander thats only 3 years old.
sorry i bought it
decided to save a few dollars on my ROS purchase and thinking that the bosch name meant a reasonable level of quality I bought this sander a couple of years ago.
I am a diy user who tends to make jewelry boxes, picture frames and small items of furniture as well as re finishing old furniture. most of my tools are Makita but I thought with this purchase I would step out of my usual box.
first impressions were that it vibrated more than I expected. stock removal was ok but not great and finish was similarly ok but not great.
another di...sappointment was when one of my sanding discs flew off mid work and examination showed that the hook base pad was now smooth and now longer was able to grip the pads. I shopped around and found a retailer that stocked replacement base pads and fitted it. the problem was that it kept happening with base pad life being distressingly short. it meant that I always had to try to keep a spare base pad in my workshop so I could replace it when the pad in use would suddenly stop gripping the discs in mid job this added significantly to the on costs of the machine and rendered any initial savings at point of purchase very redundant. I appreciate that any hook loop system has a life but this pad life was ridiculously short. the final failure was just over a year after purchase when I plugged it in and it simply refused to switch on. a low grade hum coupled with an unpleasant smell and that was my sanders last hurrah.
Mildly functional but flawed. But disc throwing problem is solved.
I needed to refinish our largish (50 sq mtrs) deck. I use Sikkens Cetol Deck which is an excellent product but you have to reapply a coat every year. You need to re-sand the old surface with 180 grit before painting and my 15 year old finishing sander clapped out on me. I just raced into Bunnings and grabbed this. It seemed reasonable quality and $150 should buy a reasonable sander...shouldn't it? (No it doesn't.)
Things I like: IT NEVER THREW ANY DISCS. THIS FAULT SEEMS TO BE FIXED. It comes with a brilliant sanding disc applicator.... It makes sure you get it centred every time. It's pretty quiet and didn't annoy the neighbours. It seems powerful enough to handle most light duty sanding jobs. It has a dust collector (see below). It seems solidly built. Things I didn't like: Leave the dust collector off. It's hopeless. It should be a bag system. This collector fills up very quickly after which, the dust clags up every little nook and cranny inside the machine making it overheat. You can't connect it to a Shopvac. After about 3 discs use, I had to take the filter box off and clean it which is quite difficult to do. The filter box is poorly designed and hard to push together. After 10 discs, I had to pull the machine apart completely (by undoing 8 screws) and clean out the clagged up sanding dust. It was rock hard! WHY does Bosch put in those stupid star head screws to hold the machine together? It's bad enough that we have to disassemble the machine to clean it so often without making disassembly even harder. I think, leaving the filter off would help stop the clagging up, but you're going to have to clean the machine regardless. Things I've learned: Don't be cheap...I'll buy a heavy duty sander with a proper dust collection system next time. Or even better, hire a heavy duty system with a vacuum collection system. I wouldn't recommend this unit to anyone.
Not sure why there are so many negative reviews for this. Having read some of them, the person has used this sander for jobs it was not intended. My own experience is very positive. I have never had a disc throw or dislodge itself. Granted, the dust collector is essentially useless but my $79 ryobi shop vacuum fits it perfectly (also bought at good old Bunnings). I make furniture and built in robes, wall panels etc and this sander gives me smooth, even finishes perfect for painting, staining etc. I only mark it down for the dust collector.
It's a cheap, lightweight random orbital, and you get what you pay for. I build beehives and cabinets - this sander makes my arm numb after a half hour. The "micro filter" box is useless, although with a wrap of duct tape you can get the dust port to connect with a standard shopvac hose. The thing throws discs like that's it's primary function. I've replaced the pad three times and it still throws discs, and once it's thrown a disc, the hooks on the pad die and you need a new pad. Fork out a bit more cash for something better. I wish I had.
great for DIY
I have only used this a few times but it does work very well if used correctly. I have read bad reviews of this product, most attributed to sandpaper 'flying off'. To test this I applied more downward pressure than needed and, sure enough the paper became detached. These machines only need very slight pressure to work correctly and I cannot fault the sanding capability with all grades of paper. It appears well made but if you are a professional tradesman I would buy the Blue Bosch. all in all this does the job for an excellent price.
As with most companys these days-they sell before they proof test.
So - I have the disc problem as well.replacement is too costly. the motor and all works, so will continue to badmouth the company to all who listen. Will do a stickon velcro and use till it dies - then not replace, Bosch has lost my good will ; I expect more from my suppliers.
Squealing, rubbish bearings
Some years ago I purchased 3 new pex270s for fairing a fibreglass boat hull....epoxy filler and highbuild. All 3 were throwing pads after less than 5 hours use (Not continuous use..4 machines in total between 2workers). I purchased decent aftermarket pads, cut them down and cut the holes. Problem fixed. However, within about 10 to 12 hours use , the armature Bearings failed on all 3 machines ...excessive squealing and no power. I have all 3 for Bosch to inspect or take back if they want some good pr for a change. I stripped them down , blew th...em out, and added lubricant which temporarily fixed them, but was difficult ( sealed bearings) wasting a lot of down-time. So I bought 3 cheap Ozitos to do the job instead, which performed perfectly and i am still using to this day.
Throws sanding discs and is very dusty but does an excellent job when it works.
Very disappointed with this machine in two ways - I am on my second base plate (genuine bosch) at a cost of 39.00 and will not be buying another one. The dust filter is useless and falls off easily. The machine when working does an excellent job but the frustration of dusting off the plate and trying different sanding pads including genuine bosch (expensive) and throwing out more than I can count because they fly off and in turn become so dusty they won't stick and again clog up the plate velcro. Unfortunately I am probably going to resort to buying a cheap brand as they do offer a good warranty usually and will replace if anything goes wrong. Thankyou
Won't hold sanding disks
DO NOT BUT THE BOSCH PEX 400 AE. Any tool that costs over $150 should not be this sensitive. After using it for 3 months it throws all brand new disks immediately after application. Highly disappointing. The cost of replacement pads is prohibitive.
And also the design doesn't allow to attach it to a shop vac so be ready for dusty dusty as the microfilter is a bit of a gimmick.
Didn't last 6 months!
I have had this sander less than six months and I am already ready to scrap it. Like many other users have described, this sander keeps throwing pads. On top of this, the filter is useless. It catches some of the dust for a while, then releases it again in a cloud when you change the position you are sanding in.
This sander's lack of longevity is a surprise as I am not using it that regularly. I am a home handyman and only use it about once a fortnight/month. Even so it has lasted less than six months. What a piece of rubbish. I should have gone the Makita equivalent or even the Ozito as some other people have suggested.
Throws pads and emties the contents of the filter over the user.
Great little DIY sander
I do a lot of DIY projects & this little sander has proved to be quite the work horse, with plenty of power to get the job done. It makes a boring job quick & easy. It is reasonably light weight, with a comfortable grip & easy to handle, the sanding discs are quick to change, & the speed is altered with just a brush of the thumb.
Light-weight, powerful, easy to use.
Must take care changing the sanding disc, as the velcro grip on the discs is stronger than the glue to the base of the machine.
Parts very hard to find!
We are in the building industry so are confident with this brand. We bought this sander recently to sand decking boards at our own place and it worked really well until the velcro back on the sanding pad became less grippy and we kept loosing the sanding paper. We went back to buy a replacement at Bunnings; not carried. Online; nowhere to be seen. There were some PEX 200 replacement pads available but there wouldn't fit; seems like they deliberately have the fixings in a different location so you can't use the pads from other models. As the Pex...200 pads were around $30 and the cost of a brand new sander is $80 it's nearly not worth it. Really disappointing for a unit that has done less than two days work to have a major part wear out like that and then not have the parts readily available. Not expensive. Parts hard to find
Had to replace my heavy duty GEX 125AC Bosch sander recently. I guess I must have been wealthier in my younger days as I couldn't afford the commercial grade replacement so settled for the "DIY" model. Stuck with Bosch as the previous one lasted 10 years so I figured even their cheaper ones might outlast the even cheaper competition. First up - this is quite a good sander and does what it supposed to do. What has brought me to writing this review is it's one major failing and that is its useless "microfilter system" dust box. This thing never w...orked from day one. Removing and replacing carefully as poorly described in the manual sees it falling off all the time with dust going everywhere. Even when empty and me holding on tightly with my spare hand, dust still gushes out of every small crevice of the filter despite being securely fixed. The old one had an air bag which inflated when turned on and did a satisfactory job even after 10 years. I'm looking for a flexible hose I can attach to the dust outlet to have the dust directed away from me. Consider this before buying. cheapish, light, sands well hopeles dust filter system
Throwing the sanding discs
I have a Bosch 400AE sander and based on my current experience would never buy another one. The machine has constantly thrown the sanding discs and a search on the internet shows this is a common problem. Bosch has underengineered the velcro on the pads and you need to do modification to the pad to get any work out of it. I am on my third genuine pad so replacing pads is NOT the answer. Based on other internet posts I am now going to drive another 30 kms to buy some velcro and try and modify the pad myself, on top of having already having d...riven 90kms to get the 3 genuine replacement pads - believed it was something wrong with me and not the pads!! I think the electrics on the machine are of high quality unusabel in its current state due to throwing discs
Bosch Orbital Sander
Excellent - it is powerful and just goes and goes, does the work of much bigger sanders and is economical on sanding sheets. It's capability in doing finishing sanding is very professional. However, mine is about 15 to 20 years old and I have worn the velcro from the sanding pad and I can't find where to get a new one.
Reliable, powerful, ease of use, speed range for different sanding tasks.
The velcro can wear off or be damaged.
Questions & Answers
WHY does the dust collector keep falling off. There doesn't seem to be anything there to keep it over the o-ring.
My sander has a very tight-fitting dust collector, but it appears to rely only on a long neck with a few bumps on the end to hold it in place. Because of the wrap-around sides of the collector, it is difficult to ensure that it fits over the o-ring without distorting or displacing it. I twist it from side to side slightly until it is seated. If it starts to wear, or if it was not made with a tight fit, then it would easily fall off.
Difference between the PEX300 and the 125-1ae? I cant seem to see....
Where can sandpaper be purchased for the Bosch PSM 200 AES Multi Sander?
