I recently got a set of Dremel's fairly new "EZ-Lock" cutting wheels for plastic, and the special mandrel they require, and I am impressed - I have yet to wear out the first wheel. More expensive than the red junky wheels, but now I see it's probably more cost-effective too.
These are the disks I use, EZ-Lock for Plastic and Metal, they are quite possibly the best cutting wheels I've ever had for the dremel.
I looked all over the internet I couldn't find anything on a precision extension. I have metal cut-off wheels and I have pretty steady hands, yet I still can't make straight cuts. So I was wondering where you get the precision extension or any tool that makes perfect straight cuts.
I'm pretty sure that the accessory he was referring to is a Craftsman Shaper Table very much like this
No bob, that's in fact NOT what I'm talking about and if you'll note the date that I was all excited about smoothy my handles, you'll note I wrote this post WAY before I got a router table attachment for my rotary tool.
