You know the stem part of the t-molding -- the part that actually inserts into the slot in the wood? That bit has to be trimmed off in order to bend the t-molding around corners and such, right? Well, my t-molding is made of aluminum. I won't exactly be using scissors or a utility knife for the job. I had planned to use my Dremel tool with a diamond cutting wheel, but somehow my Dremel tool disappeared between Utah and Florida when I was moving last year. I have searched high and low (and even gone through another move) and am absolutely sure I don't have a Dremel tool anymore.

So . . . I need to get some kind of tool to trim my t-molding, but my decision before was based largely on the fact that I already had a Dremel tool. Now I'm wondering if I wouldn't be better off using something else, like an angle grinder. Either an angle grinder or a generic rotary tool can be had from Harbor Freight for about $20-$25, so either one will do about the same as much damage to my wallet.
Which of those (or what other tool) would
you use and why?
