If you're using the StewMac circle cutting jig for rosettes, and a dremel, I'd like to ask a question.

The only bit I can find is significantly too long. It's a downcut, spiral bit but as short as I can make it is too long by about 1/2 an inch.

Anybody using this setup got any advice? Thanks in advance for your time.

Bill that's the outfit I use, with the new circle cutter base. I use the Stew Mac downcut bits and they are fine with plenty of adjustment.

Are you adjusting the base? You can elevate the base.

Brock, I "thought" I was adjusting the base, but I'll mess with it some more to make sure I'm on the outside of the screw travel.

I have actually used the spiral bits that are sold by Dremel for cutting wallboard. I shorten them with a cutoff wheel then resharpen the tip. I prefer the proper tool, but these will get you by in a pinch.

Those bits are very hard!
Put 3/4 of the bit -cutting in a vise-protect the cutting edge if it hits the mwtal -you will have 1/4 of the bit that goes into the collet sticking out-give a hard whack with a hammer -towards the floor or a empty wall and the that piece will fly off!
Kids do NOT try this at home!
pat attention to the direction the excess is headed in!
Might be a good time to invite the X to the shop!
Sorry

Ah...I get it now, the bit I have is MUCH longer than the bits sold by StewMac for their cutter. I'll invest in one, or more, of those bits from SM. I don't like the idea of cutting off and sharpening the dremel bits. Thanks greatly for the information guys. That's why I love this place.

Bill,

Try McMaster-Car for bits as well. The one's I have gotten have been
good quality and they are a bit cheaper than SM. Search for end mill
and you will find them. www.mcmaster.com.

Oh No! Not another learning experience!

I have use every thing from a 2 flute 1/8" cutter to 1/16" down cut bits. Your collet nut should be about 1/8"-1/4" above the top side of the base when the cross bar is adjusted down to its lowest position. this should be low enough to use any dremel type bit.
