Will the bearings on a Dremel survive that degree of side-load?
I have one of these and have used it extensively. Although functional for small projects, do not expect it to tackle bigger projects where you need route deep into the surface or cover a large area. Also, your Dremel will overheat and you will put too much stress on the bearing if you attempt to go too fast. In addition, the plunger stop and the guide are understandably not deigned for precision work. That said, it is definitely better than attempting to use a chisel or using a Dremel guided by hand. My one recommendation is to unsure you invest in quality router bits, such as the ones actually made by Dremel. You will blow through the cheap ones fast and they will not cut smoothly.
