Question:

drill flat bottom hole in aluminum?

Hi,I'm new to machining and I have a (probably) basic questionI need to drill a 17mm hole 1mm deep in the middle of a block of aluminumThe bottom of this hole must be flat.I have access to both a mill and a drill press.

Answer:

If this hole is just a recess, you have no alternative but to mill itBut you would need a rotary table so as to be able to form a round recess with a flat bottomYou cannot get a flat bottom if you try to use a cutter that is the same size (17mm.).
