Someone recommended these a while back. The 280 grit worked very quickly; the 120 flap wheel took off material too fast. The sanding wheel used the spring mount that I happened to already have from the cutting set. It wore down pretty quickly, so getting a bigger pack of off -brand ones would be more economic. So much easier than sanding by hand!
there’s an addon, called the Flex-shaft, for the Dremel that lets you use it like a pen, fucking love that tool
Yeah! I considered breaking out the flex shaft for this one but ended up having enough mobility without.
I have a big bag of knock offs from Amazon and can confirm that they work well!
Don’t forget that an orbital sander with a thick foam pad between the base and sanding paper also does a good job of rounded surfaces. You can also get drill/dremel bits that provide similar functionality for smaller hook and loop discs. Eg. https://www.amazon.com.au/HEATSHAKING-Pneumatic-Attachment-Industrial-Polishing/dp/B0G499XZLX
I find this lasts a bit longer and more versatile than a flap wheel.
There’s also the super diy approach by making a custom shaft to hold standard sand paper which works well in a pinch https://www.instructables.com/Simple-DIY-Flap-Sander/
I ended up using those to sand some finger grooves in cutting boards. They’re surprisingly aggressive.
