Flush cut router bit for Dremel?


Has anyone ever seen this type of bit in an 1/8" shank to fit a Dremel? It would be similar to the type of router bit used to trim laminate for countertops or to cut multiple parts using a template. I've searched and would assume someone would sell one but have not found anything yet.

Thanks, Scot

Your local hobby shop of harware should be able to help you with availability.

Try the cut on a scrap piece of like-material first. Keep the RPMs slow as not to burn the wood and bit.

I didn't see anything like what I'm looking for. See the bit by clicking the link below. Looking for something like it.

I use tungsten-carbide bits from McMaster-Carr. Technically they are die-grinder burrs, but they work fine in the Dremel tools. They cost ≈$5 nowadays, but I have four and they have lasted almost 20 years in all sorts of use.

For the use you propose, I'd recommend the double-cut (faster cut) but the trick is the 1/8" shank, 1/8" diameter head which does a 1:1 transfer. Just adjust the seating of the bit in to the dremel so the smooth shank contacts the pattern and the teeth engage the raw material. If you use the radiused-end, you can plunge-cut into soft materials as well.

McMaster is where I got the ones I have, but they are available from a dozen places, and the pictures are from a Karnasch catalog.

Nevermind, those have an 1/8" cutter diameter, but a 1/4" shank.

Okay, so you're looking for a trim/bevel bit with a live bottom bearing? Sorry, I haven't seen a bit with such a small bearing either. As you may know, the extension on the bottom of the bits in the Dremel link serve the same purpose, although a live bearing avoids burning the wood, and serves on a trim bit to bring the material you're removing flush with the work piece.

I'm afraid that chances are you'll only find the extended fixed "bearing" on a 1/8" shaft router bit. If you do, PLEASE post where to get them!

Thanks for the ideas, guys. I guess those McMaster Carr bits would work, but would probably be better on a router table setup since the "bearing" surface would be on the bottom, closer to the collet.

EJ,
A ball bearing would be nice but not necessary at all. It's a shame Dremel doesn't make such a bit already...wonder why?

That when people trim laminate, they use 'real' routers? The cost of the bearing? . . . a bearing that is not only smaller, but must turn at higher RPM?

You haven't explained why you want this; what the purpose is. Laminate trimming is one thing, but pattern cutting and sign routing is normally done pattern-above, stock-below.
