Money making sander

published

Backing plate with nylon hook velcro is a designed to fail and have you buy new heads. Head gets hot due to friction (so don't press even a small amount !!) then the hooks change shape so the sanding discs don't stick and get thrown. I'll research and check the design more carefully before next purchase. Machine works fine when new head but doesn't last long. I'm on my 3rd and its getting expensive to run this machine. Unexpected.

Purchased for $200.00.

failed speed contoller

published

after a couple of times using this model the speed controller failed and the machine would not run lower than half speed, then it failed altogether, replacement part is $44 from https://www.toolspareparts.com.au/bosch-pex-300-ae-3603ca3040-spare-parts.html I should have returned at the first instance of failure but you know what its like just wanting to get the job done and move onto other bits so did not follow up on warranty, wish I had, also the dust catcher is pretty much useless, now replaced with Ryobi, so far so good.

Poor dust catching function

published

the sander works OK but the dust catcher is useless, dust clouds are the order of the day. Even when I cleaned the filter and took care to refit it to the machine, it still emits dust from around the lid. Checked that its fitting Ok but no change. Disappointing dust catcher.

Throws sanding discs. Velcro not fit for purpose.

published

As others have found these Bosch 400 sanders throw the sanding discs. Very poor velcro attachment plate used on backing pad. Not fit for purpose IMHO. I've already replaced it twice with the Bosch OEM backing pads, no better, they go bad soon after. Bosch OZ know about this problem yet have not offered to replace these defective parts nor owned up to the issue. Very poor IMHO. Web searches reveal this is a common issue.
Their response is to tell readers to call their helpline where you will be told crap by someone who knows nothing and offered nothing useful as a remedy. I will not be buying another Bosch orbital sander not will I recommend them.

Frustratingly disappointing.

published

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.

Mildly functional but flawed. But disc throwing problem is solved.

Not Great

published

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.

Throws sanding discs and is very dusty but does an excellent job when it works.

published

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

Yes I have had that sort of things happened before once after using 6~7months.
But I thought that happened my casual worker press too hard down.
So I just replaced.
It was under $100 not like $260 or even $700 like fesco?.
It is cost effective way.

Hello, I had the same issue, opened it up to check if the bearing was in working order but the bearing was fine. I couldn't figure out what was wrong with my sander, very disappointed since it was relatively new and not used too much. Check YouTube , it might help you. Cheers

What did reviewers think of the Bosch Random Orbit Sander?

Reviews were well and truly mixed about Bosch’s random orbital sander. Among the positive feedback, the sanding tool’s power output and variable speed control was praised, with reviewers saying that it helped them get medium to large-sized jobs done in a relatively short amount of time.

The sander’s stability was also appreciated, with reviewers noting that it was easy to control and reasonably lightweight.

A notable pain point among negative reviews had to do with the discs, with some reviewers staying that the sander threw them off the head well before they had worn out - this made using the tool inconvenient and costly for them.

Another pain point was that the dust collection system was ineffective - reviewers said it didn’t catch much dust, and frequently fell off the tool.
