28594 PS 13 Corded 12-Volt Pen Sander

This is an EXCELLENT little pen sander that works exceptionally well at sanding into those hard-to-get places. Don't force it, just let it do it's thing. You'll need extra sanding replacements because it goes through them fairly quickly, but even the rougher sandpaper leaves the wood at virtual finishing condition. You can save on replacing sand paper by turning them on the sanding heads. They stick really well, even when turning them to use the other end of the sandpaper. If I had to do it all over again, I'd still get this but without wondering if it was going to do the fine sanding like I hoped it would, because it's great. One thing, it is 12-volt, so you'll have to get their transformer for this to plug into for it to work since it will not plug into the wall plugs. This is the only possible downside to this, but it's worth it for how well this works.

I bought this sander for work on a particular model ship project (to sand in the camber of the main decking), and boy, am I glad I got it! This piece gets into places and speeds up finicky work like you wouldn't believe. The control and agility of the thing allow you to work very rapidly and exactly, once you get the feel of it. One suggestion, both to the manufacturer and the buyer: Courser-grit pads would be welcome, instead of having to glue them on yourself. There are places to get into that need a more aggressive touch, and the lighter-grit wears quickly. All in all, if you work on miniature projects, this thing is indispensable.

Listing makes zero mention that you cannot use this as is. You must buy a power converter, and that's another $100+. There's no need for it to be designed this way, EXCEPT to force you to spend more money on their products, just to make the thing work. There's a good reason this is tagged with "Frequently returned item."

So yes, as many reviewers notice, there is the power connection issue. This sander uses a unique three-pole connector, though only two poles are actually in play. The catch? It’s meant for Proxxon’s own power adapters, which don’t come cheap. Opting out of buying their pricey adapter, I modified the cable myself to fit a standard 5.5mm x 2.1mm connector and hooked it up to a 12V, 5 Amp switching power supply, which matches the specs of the Proxxon adapter. Despite the sander not needing that much current, it’s working seamlessly now. Moving on to the sander's performance, it’s impressively lightweight and feels comfortable in hand during use. A downside is its quick consumption of sanding pads. I’m still on the lookout for how to efficiently use regular sanding paper with it. My primary reason for choosing this tool was for sanding paper sculptures, particularly in tight spots where hand sanding is a challenge and rotary tools risk burning the paper. The Proxxon’s linear sanding action has been effective here, despite the sand pads wearing out faster than preferred. No problems have surfaced so far, which is a relief, especially since modifying the power cable voided the warranty. In summary, the tool is highly functional, user-friendly, and adept at sanding without causing overheating. However, the non-durable sand pads and the hassle of the proprietary power connector are significant drawbacks. If you’re not up for purchasing the expensive adapter or modifying the tool, you might want to consider other options. I’d rate the tool itself highly, but given the adapter issue, I feel a four-star rating is fair without being overly generous.

This requires a power supply of 12 volts which can rigged up easily or else buy the somewhat pricey Proxxon Power adapter which has the ability to control the voltage and therefore change the speed of the oscillations. I had mine connected to a regular DC adjustable power supply. Polarity of the cable is marked on the plug.

Proxxon pen sander PS 13; I had to return my first sander after about 3 hours of sanding. The motor would run but the piece holding the sandpaper didn't move. Due to the fact that I needed a small sander I ordered a second one. Amazon did refund my money for the first one. Because I only had a small amount of sanding left, the second one finished in good condition. About two months later, I needed the PS 13 again. After about 2 hours of using the sander I noticed it started acting like the first one before it stopped working (the stroke gets longer). Because the 30-day return policy had expired I took this one apart. A disc that is mounted to the motor shaft has a 1/16 dia. hole that is offset from center. The pin that fits into this hole came loose, opening up the hole. The end of the pin that protrudes from the disc fits into a slotted hole, also plastic, that creates the back and forth sanding motion. I glued the pin into the hole and all is well so far. As far as recommending this product, if you need a small sander it works great, but because of its short life span and $40.00 price, I would try a different company next time.

I bought the Proxxon micro sander because I hate sanding my 3D printed objects prior to finishing. To be honest, I was quite skeptical about this sander as the reviews were not all kind, but I hate sanding so much I purchased it anyway. I did NOT buy the Proxxon power supply unit as I have a 3 amp 30 volt variable power supply, but when it quickly arrived (Thanks Prime!) I took a chance and wired it to a an old 12 volt, 1000 milliamp Linksys router power adapter I had on hand. This so far has worked out fine for my usage. The sander is more powerful than I had expected and is actually useful for sanding my plastic models! I was worried that it might tend to melt the plastic, a problem I encountered when using dremel type tools for sanding, but the Proxxon, with its 'side-to side' motion does not overheat the plastic unless you really force the issue. I am glad I decided to try out this great little sander, it makes finishing a much less arduous task!

I'll be the first to admit I have lots of ambition in theory but in reality, when it comes to project completion, I lack motivation. I start a project all ready to go but when it gets difficult, I take an extended break. Yeah, lazy. But at least I know it and got this tool to make my extended breaks less extended. See, this tool helps me in my furniture restoration projects. I hate the sanding part of the restoration but in the tiny crevices or difficult angles, this thing makes life so much easier! I actually don't hate sanding as much. You do need to purchase the power source for the US, but you can bet, if you are lazy like me, it's well worth it. See, I buy the adhesive rolls of sandpaper and make my own sandpaper pieces. This way, I save a ton of money and get any grit I need. It is a pain in the booty to do but when I think of all the money I've saved doing so, it's worth it. I just cut a bunch in my spare time so it's ready to go when I need it. So, moral of this long review, be lazy and get this thing to make your life easier.

Single best product I've ever purchased on amazon. If you are post-processing SLA or FDM prints and you want a quicker more accurate way of sanding just buy this. I contemplated it for way too long, could've saved myself a lot of sandpaper and energy. I don't even mind that you have to buy the power pack separately as together they still come to a decent price. Just make sure you buy the power pack with the alternating speed dial and don't bother with the sandpaper stickers they come with, buy sandpaper sponges https://www.amazon.co.uk/dp/B0CWRTZ325?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 and cut them to size and glue gun them onto the plastic sticks.

Bardzo dobre do drobnych prac.

Buena máquina. Resistente y muy fácil a la hora de intercambiar los cabezales

Don’t be a weirdo and think that you can use this to sand a chest of drawers or something : it’s a Precision Sander For Very Small Bits. I use it when getting into tiny edges or corners for dollhouse or miniature terrain and it works a treat. You do need the 12V transformer tho so be aware it doesn’t work on mains power.

Tried it a bit and it works great so far. I'll use it sparingly for 3D and resin prints. A warning though. This can not be connected to a normal socket as it needs an adapter. Proxxon sells one but you can hack one together if you want. It needs 12V 2A power. I used an old ATX PSU from a compuer, shortened the PS_ON pins to turn it on and used one of the 12V cables to attach the power and GND to the sander. Not pretty and very bulky but it works.
