    Default Dowel pins for punching small holes?

    Making a die to punch out a large (8") part from thin aluminum and needing to have several 1/8" holes. The holes don't need to be high tolerance. Am thinking of using some dowel pins with ground off ends for the male side and milling the hole for proper clearance on the female. Is this how it is commonly done? Other ways of doing it?

    I have used dowel pins as punches for limited use. Given the material you are punching, you would want 1.5 to 2 thousandths clearance on the dies to punch clean holes. The larger the clearance the more the hole edges roll over. I would ream the die holes.

    If you're not going to buy punches and do it right, at least use something that is through hardened like a drill or reamer blank.
