Ok Guys. Diamond Wheel. Diamond bits, these things don't have to be expensive, you can get ones that are similar that still work.
I've been doing a lot of cutting lately, customizing, wood, steel, aluminum, plastic, tile, grout. Polymerized acrilic fiberboard, whatever, you can get a tool to cut it without paying an arm & leg for it. Go to Amazon.com.
I've had a set of these that I bought at Harbor freight for years. I've only burned out two but at this price it doesn't much matter:
Cases are thin anyway, if you don't have the EZ lock, don't let it stop you. There are plenty of Dremel substitutes & thier suppliers out there, they're all 1/8" mandrel sets that match the dremel in most ways. As long as it says "Rotary Tool" and has a 1/8th inch bit, it will work. Oh, on these diamond wheels, it's not just coated on the edge, you have a little burr that you can't get off, use the face of the disc. It's diamond coated too!
Wanna cut a door frame to put in the hinges. Toss your chisel in the tool box, get yourself one of these babys:
Comes this way too:
Screwed to the Mandrel, no EZ lock involved. Just gets my goat that this came out 2 months after I got a whole list of Dremel equipment
When I'm awake enough to understand what I'm looking at, I'll post some of the Dremel "alternative" stores for you.
