I want to cut/drill/grind a small drainage hole (maybe more than one) in through the base of a plastic terrarium. I don't have a drill on hand but I have a Dremel Micro rotary tool. Is it alright to use one of these bits to do this kind of thing? Which one would be best?

The Dremel will do what you need here. The 2nd bit from the left will work perfectly. It will drill a small pin hole to a larger hole the size of the largest portion of the bit

  • Cheers. That one worked alright @ high revs. The others, not so much. I expected it to cut a bit better though; it seemed to melt the plastic more than anything. End result is countersunk.

  • @tjt263 Yes, that's a common result with plastic if you don't take your time - heat will build up and it can be nasty trying to get molten/re-hardened plastic out of the bit. Either set a lower RPM, or spray such surfaces with water in future, to keep them cool. A Dremel drill press or jig can make this a lot easier, but I don't recommend the stock Dremel drill press.

  • The Dremel drill press is okay, but not compatible with this particular tool because there's no locking collar below the collet.

  • Not actually sure what these bits are intended for.
