I'm a mouldmaker (specializing in thin-wall plastic injection moulding repair/refurbishment). We have Japanese, German and Swiss shaft-drive and direct-drive polishers/sanders. These units are meant for 100% duty cycles, all day, everyday. Thus, the price of these units are cheap car levels. Having a bunch of these would be awesome for quick touch ups where a 10 minute tool change on our power unit or hand set would have to be done. The problem is I doubt these would hold up to our abrasives (everything from blasting silica to 3 micron diamond paste) and all the incidental hardened metal dust. Dust extraction or a vacuum would help mitigate those issues.

I think these would be a great addition to anyone's toolkit needing occasional fine work.

Thanks for sharing!

And yes, I agree with you: Rotary tools will get the majority of work done. Roughing, smoothing, to fine polishing rotary tools do 95% of my work. Reciprocating is required for directional texturing, draw stoning, and shapes that a round head cannot accomodate.

It seems like a handy tool to have in your toolbox. One thing people should note, is while these work really well on raw 3D prints, they are TERRIBLE for primed pieces. The sand paper gums up and becomes useless in seconds, so if you prime a model and see you have more sanding that's needed, these will barely work so try and get it perfect before priming.

lol the Nik Nocturnal “Heavy” was a nice touch.

Thank you for this! At 4:07 you basically say that the "ES-P" tool (rotary instead of linear vibrating motion, it can indeed use self-adhesive sponge sanding discs) is more effective at removing more material at the same time, but my question is: isn't the rotary tool too agressive? Because we want to sand and smoothen a plastic surface, not create additional scratches or even dips in it… Currently undecided between these two tools. My specific user case scenario: get rid of the very small yet many pock marks (tiny raised bumps) left after support removal on otherwise smooth (resin) 3D printed objects.

I have both and they have there pros and cons price wise it’s fair for the functions these offer as far as sandpaper u can use types just by double sided tape apply it to the paper and stick it on the shaped head and cut fairly easy to do. Just can be time consuming vs precut ones.

Thanks for sharing this video. I'm interested in buying the tool and your video made me realize that I don't need to buy the extra heads separately as they're already included 😊 Thanks again 👍🏼

Hey EV
Thank you for sharing, it is nice to see what is out there.
Happy Easter and take care 😊

Don't know if this was mentioned in this section, but this also has model kit builders and customizers in mind; when dealing with nasty nub-marks, especially those placed in the worst places ever, this tool could come in real real handy for this sort of intricate task + may save time in sanding in general; DSPIAE's best friends with the Gunpla community

Thanks for the video, I've been looking around for a reciprocating sander for garage kits, and this one seems to fit the uses I need while also not being $80+ (Mr Hobby I love you but your sander is so expensive). Looks like I'll be picking one of these up soon

[WarehouseWilgus]

ive been enjoying it since my hands shake a bit and i cant get some of the parts on smaller plastic points. great video!

[Shooter_FPV]

I do a LOT of 3D printing, mostly with resin. Got this delivered a few weeks ago, it's actually really great. The tool heads it comes with are super handy. I just need to know where I can order replacement sanding pads here in the US.

Fascinating! I have two rotary tools I use for this purpose at the moment. The Hoto battery-powered rotary tool is quite nice. I like that this one has some flat heads, but the tiny size implies that the sandpaper would load up very quickly. I might look around for an oscillating tool that’s a bit larger. Thanks for your quick and to-the-point review!

[JUST_PAINT_IT]

Another great tip! Thank you for sharing. I think I will go with the little brother version.

[kvernesdotten]

Im gonna try ordering this, seems perfect for polishing stuff with awkward angles, like a knife blade up against its handle or bolster. Lets hope huba buba express actually bothers to send something this time haha.

[shannonorourke]

Very interesting! I’m considering buying both..they seem to be pretty lightweight as compared to a Dremel.

[anthonyt]

Excellent summary. Great video. Thank you.

Lithiums are damaged by sitting around fully charged. They are also much more dangerous to the courier. So it's bad they're shipping them at full charge, they should be at 40 to 50%.

[azraelraven]

I just bought one of these, and it's great for getting into tight spaces. I'm really very happy with it... though it's more of an addition to the rotary tool rather than a replacement for it.

[TheIcemanModdeler]

Neat, i was looking a while ago at the small dremel but didn't bother with it, wonder if it's better.

[johnconnor]

Surprised there isnt a option for a sanding head that looks straight ahead so you can use it straight up and down instead of trying to go at a angle only
