Dremel bits

What Dremel bits should I use for sanding foam smooth and nice? I got one suggestion earlier but it was only available in Canada.

Just be careful Lieutenant Jaku the rubber on those sanding drums do not hold up well to heat. Sanding along the spiral band is fine, but if you bump the tops and bottoms too much they are then very hard to change the sandpaper. This is my experience in fiberglass sanding. Foam is probably not going to mess up the bits as quickly.

Bingo, the bits don't mess up as quickly on foam but that doesn't mean that it won't.

Another thing to look into is the max duty cycle of the tool/bits. Some things simply aren't made to withstand continuous use and in the case of Dremel tools and similar rotary tools many of the operator manuals have this expressed in minutes per hour that the tool will work reliably for without fear of damage due to overheating under normal conditions. Like Duke said, rubber sanding drum interiors have a low duty cycle due to deforming from heat and will be damaged long before your tool wears out, some grinding stones will be the opposite.

Take a look at the warranty and owners manual of your tool (shocking, I know, reading the paper instructions (who does that?)) to find a whole bunch of helpful bits of information. I even found a prize draw voucher in mine!
