Dremel carbide cutting wheels


I need to do some channeling/hollowing on some existing wood framing members and saw this video.



Does this work really as easy as it shows in the video the way they notch wood and cut channels in it? Wouldn't the thin disc break if pressure is applied in the direction of the axis?

I don't mind getting them to experiment with a bit but they are being sold on eBay for $67 for a set of five so it's pretty expensive.

Anyone know if they really work, or better yet, are they better than other "carbide cutting shaping wheels" sold for $10, $15, or $18?

Since no one really knows exactly what it is your trying to acheive it's hard to say what tool is needed.
Sounds more like a job for a router.
A Dremal a pretty light duty tool for any heavy cutting and hard to keep straight.

Joe gave you some sound advice,but let me add to it.
Right tool for the right job, from the movie you posted I would use my 7" grinder with a cut-off wheel which compared to the price you posted would buy a lot of them.
I would consider a Carbide wheel for products like grout and tile but here again a Diamond wheel for my grinder is only $10 and last a very long time.
In reference you have Small Medium and large = Dremal ,Roto-Zip and 6"-7" grinders.

Dremel carbide cutting wheels


The specific tasks I have in mind (which is not to take away from the general tasks they could do) is to do channeling and notching around existing framing members - wood studs, headers, top plates etc...in order to route conduits and pipes etc...right now I either drill holes or use a sawzall, however, in tight spots, especially when the wood members are against concrete wall, or in a right corner in the attic, I found a sawzall often have to OVERcut in order to get a notch in.

What appeals to me is the fact that these wheels showed in the video you can use a much smaller dremel and make a small channel quickly and easily.

I don't need tools to cut, notch, drill or channel new members to be erected, I have tools for that. What would be nice is a easy, light, handy around tight corners tool that could notch or cut something quickly without overcutting.

I have a dremel clone, a Craftsman rotary tool, the small one (not a rotozip), and never used it. When I saw those wheels I thought may be those could come in handy for those situations.

I wouldn't use it to cut new copper pipes, I have a tube cutter for that. I wouldn't use it to cut new ABS or PVC pipes, I use a chop saw for that. But for tight corners on PVC I use a cable saw, for copper pipes may be this could be useful when there is not even enough room to swing a tube cutter around?

So I am thinking only EXISTING installation in some nitch applications.

I'd be using my Rockwell multi Crafter to do those jobs.
It will do all those and dozens of other jobs that tool could never do.

22 tooth carving disc from harbor freight: http://www.harborfreight.com/22-toot...disc-7697.html. Its a chainsaw cutting wheel for your grinder. Guys use them to carve tiki carvings from big logs.
