Metal Cutting Router Bits
Does anybody have any experience with those spiral-type metal-cutting bits you can put in a wood router?
I've been cutting rusty old galvanized steel barn roof panels and old license plates for the wife for her crafts. I've been using a metal-cutting wheel and a jigsaw with metal-cutting bits, but am going through them like crazy.
I thought it would be nice to use the router/router stand I have, plus I think it would enable me to do smoother, more detailed work.
But, at roughly $30 a pop for bits, I'm not sure if it's worth it.
Does anybody have any advice on what kind of bit I should look for to cut through this type of material and how long a bit might last doing so?
It seems like some of these bits are designed to work with much tougher/thicker metal materials so I'm hoping I'd get quite a bit out of life out of one bit using it for the corrugated steel and license plates.
