The inserts used turn the OD and Bore the ID always have a radius tip. Even if I program a perfect 90 degree angle the corner will always have a radius the size of my insert (either .031 or .015). On some applications I can’t have that small radius because the part needs to fit flush with another component and that small radius would be in the way. So I need a tool that can go in there and create a small dip to break off the rounded corner. The image I attached has an example of this. A lot of times it can be accomplished with a small grooving tool a .125 grooving tool is to big. Do any of you know of any tools I can use to achieve this? On OD I can usually get a away with a cutoff tool, but any suggestions for ID corners. Some parts have a bore depth of .125, so this tool would have to be way smaller. TIA!!
