I need some advice since I'm new to this... Say I have an end mill tool that has a shank diameter the same as the cutting diameter, and a cutting length of 0.7 inch. If I need to hog out more than 0.7 inch deep, is this asking for trouble? Theoretically as you progressively cut deeper, the hole has been cleared for the shank to get by, but it's line to line clearance. I'm not talking about drilling a hole the same diameter as the shank/cut, i.e. simply plunging down. For example assuming I have adequate shank length and the tool diameter is 0.25 and the shank is 0.25, can I use this for hogging a hole that's 1 inch diameter and 1 inch deep? Or am I asking for trouble because there's a change the cutting diameter is a mil or 2 smaller than the shank? I'm asking for advice from people that are familiar with hogging aluminum deep. I don't want to do something "stupid".
