I am working on creating an extension for a 9/16 counterbore cutter. This thing has a 1/4" shank on the end that is 7/8" long. This application calls for the addition of a drill rod extension to this cutter, about 9" long it happens to be a 1/2" drill rod. I need a way to hold the cutter inside a bore in the drill rod extension. I am thinking a press fit would be best. Maybe I am wrong? Now the question is if a .0015" interference fit will do the job? Nothing is worse than to see that extension slip around the cutter shank when it really should be driving it. I was thinking, just a simple MAPP torch on the female end of the extension and worse case scenario, have the cutters 1/4" male end sit in some dry ice. Just use some gloves to slip the two parts together and wait till they cool and warm to room temp. Will this work?
Thanks guys
