Yes, overhang for clamping and I will never have another work table/bench without a quick mount receiver. It is just simply too handy. And put a piece of chanel (or angle with oriented like a "V") on the end with the top below the surface. Use that to lay pencils, scribes, drill bits, whatever in. And power strips down the front edge to make it easy plugging in stuff without going across what your working on, invariably getting in the way or snagged. And all the way across the back side, peg board and/or storage bins. For the price, I like the larger angled yellow bins from HF, usually around $30 on sale. Though steel is better if you want to drop the cash, and you can get those from Enco pretty cheap. And finally, add quick holster/hangers under the front ledge for things you use a lot. I've got (or had) some for my drill motor and grinders to keep them handy (to pick up without looking or turning loose what I'm working on) but off the top.
