Morphology
The meaning 'to make a small indentation or hole in the middle as a guide for drilling' follows directly from combining 'center' (middle) with 'punch' (to make a hole/indentation). This is a simple location+action composition common across languages and contexts—although somewhat technical, a B1 learner who knows both constituents should be able to infer the meaning.
Etymology
The noun center punch is a small tool with a sharp point that makes a dent in metal or wood so a drill bit will not slip. It puts a small mark at the piece's center with a quick punch, so the tool's name shows it makes the guide mark for drilling.
