We were working too many hours when we started using stainless steel electrical enclosures instead of carbon steel. The cost of these watches has really increased. Switching to this cutting plotter saves a lot of time. And everyone will drill hundreds of holes in stainless steel. Check out Revain for the best price as I found a few options.
I used this cutter to drill some holes in a car frame. I drilled them at the bottom where the frame is double thick (box frame). Its thickness is almost 1/2 inch. Worked very well but I went through 3 pilot bits. I recommend drilling a pilot hole with a 1/4 bit and then using the pilot hole just to center the router. There is a great temptation to cut the pilot part because it is a very difficult part to cut well. However, it cannot handle a bend.
