I saw a video where someone glued sandpaper to a hole saw then used a drill press as a kind of drum sander for sanding curves. I don’t have a drill press but is it safe to put the hole saw in a router mounted in a router table?

Even on it’s slow speed a router will be way too fast. Don’t do it.

Holy bad idea, Batman! As the others have said, it would be extremely unsafe. Imagine all those sharp teeth pointed up at you spinning at thousands of RPM’s. Also, I doubt they would fit the collet very well if at all, so there would be a lot of risk of it flying out.

Okay – that one is settled. Thanks guys. Next question – I’m going to make a chip and dip tray: one of those oval shaped ones with a hole for dip on each end. I needed the hole saw/sandpaper to sand the template after I rough cut it out. Any ideas other than hand sanding????

I recommend using 3/8” mdf for the template and use a jigsaw with a fine curve cutting blade. If you have a steady hand it won’t need much cleaning up. Do the rough sanding with p60, clean up the whole thing with p120. It won’t take long.

20,000 RPM is no joke. The only thing that goes into a router is a router bit. Even then, be afraid.

just use sandpaper with a backer block (MDF/plywood/cutoff) suited to fit your intended area to be sanded (large and flat or narrow and round…) and hand sand it.

Yeah, that’s pretty much what I thought. Thanks guys. Maybe I can talk my wife into letting me buy a drill press :)

I’m glad you came to your senses. Man, a hole saw in router? There’s no happy ending there.

That one ride you want no part of and believe me if you tried it would look like some angry beavers went to town.

Tools like you are referring to will almost always have a warning stamped on telling about the maximum RPM that it can be run. I’m positive that no tool like a hole saw is rated to be run on a router. It can fly apart and instantaneously kill the operator or anyone else in the room.

With the proper coupon you can get one of these from HF for $89.

I own two of them, the older style that is a copy of the Triton that sells at Klingspor for $169.99. I abuse the heck out of them, and they just keep going. One problem, they put out enough RF to kill my radio signal in my shop when running. Other than that, on their second year, and still sanding away!
Unfortunately, they are changing the model to look like the one in the URL I listed. Unknown if any other changes occurred besides tabletop and a little body change.
