Not sure haha. I Bought a Dremel at a yard sell for like 10 Bucks and it had some in there.
If they're the solid 1-piece wheels, you gotta go slow with those or they'll break.
The fiber reinforced wheels are great, but expensive. They have a 100-pack on ebay for $12 but I don't know how good they are. Probably Chinese knock offs.
Nothing wrong here, looks good. Out of curiosity only, louvered or hole center tube? Dremel likely accounts for some/much of the can debris
Thanks for c&p.
