dremel grinding/sanding bits, will they attach and work on my drill?

Typically, dremels rotate much faster than a drill. Thus you might not get good results.

sanding some fiberglass so speed isn't needed

As long as your drill can clamp securely on the bit, I don't see why it wouldn't work. The bit is usually quite small though. Dullard is right about the speed though. I think Dremels rotate at about 30k RPMs so a carbide bit going that fast will surely cut a lot better than however fast the drill spins. It's worth trying at least to see if it will work.

Dremels do up to ~30K I think, they can also run much slower.

My ears don't believe you 😛

You're right, though. I think some have the option for 15k and 30k via a rocker switch.

Most drills can't even go up to the slowest speed my Dremel goes. My Dremel 400 XPR is adjustable from 5000 to 35000 rpms. It has a dial on the back so I can set pretty much any speed in the range.

You can get the bits to fit sure, but like others have mentioned, it might not work as well because of the slower rotation.

High speed for a drill is often around 1400 rpm, cheap ones less (perhaps expensive ones a bit more.) Sanding and grinding disks for a drill have a much larger circumference than those used on a dremel, which helps to make up for the lack of rpm's (and vica versa, they are smaller on a dremel to accomodate a less powerful motor.)

I assume you are sanding the edges of a piece of fiberglass, not the gelcoat finished surface. Once you get an angle grinder, you'll never go back. The little Dremel sanding discs are too small for any real work, and if your electric drill is any good, the glass in the fiberglass will act like sand in the electric motor and prematurely wear it out. BTW it'll do the same thing to your lungs as well, so if you have a shop vac or any vac with a filter bag, set it up right next to your grinding table. Go to the paint dept. and get special dust masks for drywall/fiberglass. Wear gloves and put baby powder on your arms before starting. Rinse hands/arms in cold water after you're finished. Unless you enjoy endless itching. Junky Chinese angle grinders are 5 bucks and you can use the grinding wheel that comes with it on 'glass. A deeluxe kit will also have a sanding disk backing plate. You'll maybe find more uses for the angle grinder than for your drill, like sharpening stuff, cutting off padlocks when you lost the key, cutting hard plastic as well as metal shaping.

Get a sanding drum or grinding wheel that's meant for a drill...
