About a year and a half ago I bought an inch and a half diameter CMT router bit with the intent of using to plane a wood surface. I am now in the process of building myself a workbench and want to use this bit for surfacing. I got to looking at it and noticed it has about a 9 degree negative rake angle. Will this cause me any problem? I plan to give it a try in a week or two regardless, but I was wondering what to expect. This bit has a bottom mount bearing,that is, the bearing is between the cutter and the shaft. I think it is a rabbeting bit, but I want to use it to plane a surface. Is this what a negative rake bit is used for? Any information will be most appreciated, thank you.
