HOTO SNAPBLOQ R-A04 Mini Grinding Set QWDMA001

I bought this mainly for post processing my 3D prints and it's been exactly what I needed. The 22000 RPM is plenty of power for sanding down layer lines, drilling holes, and cleaning up support marks on PLA and PETG prints. The cordless design is clutch when I'm working on prints. No cord getting in the way or having to hunt for an outlet near my workbench. Battery life has been solid, I can usually finish several prints on a single charge. Size and weight are great for detail work. It's way more comfortable to hold for extended periods compared to my old full size rotary tool. The grip feels good and I have way more control when I'm trying to smooth out fine details without overdoing it. Came with a decent variety of bits which is nice. I've been using the sanding drums mostly for smoothing prints and they work really well. Haven't had any issues with the bits coming loose or wobbling. Speed control is smooth and consistent. I can dial it down for delicate stuff or crank it up when I need to remove material faster. No weird vibrations or loss of power even at lower speeds. Only thing is the battery takes a little while to charge but that's pretty standard. I just throw it on the charger after I'm done and it's ready next time. If you do any kind of finishing work on 3D prints this is 100% worth picking up. Makes the whole post processing workflow way faster and the results look cleaner.

Nice tool in the hand. It has a nice balance, feels very 'controlled' to work with. Unfortunately, the hand piece I received had something wrong internally - made strange reving sounds and sped up by itself. I contacted Hoto and they were wonderful. Amazon issued a full refund - unfortunately - the return label was issued for Canada Post - which is on strike - so effectually - no return shipping! Hoto made it right and refunded the tool without a return. I was disappointed that my hand piece was defective. I loved how it felt in my hand - the tool boxes were lovely - lots of bits - and for travelling - the packaging to put it away, transport, and get it back out to use - is excellent.....I will order Hoto again.

Great design, and construction feels pretty solid. Magnets in the case are not strong enough to keep it stuck on my metal filing cabinet. Tool itself is a little loud and the slider is not super precise. But having a cordless rotary tool is very useful.

Very handy and convenient little tool

Overall good tool. Could use a bit more power. Would like to see a cut off attached with wheels.
