Recently I needed to drill centered holes through some wood blocks, and my Rockler Clamp-It™ Assembly Square found new purpose as a handy drill press fence. It offered full contact surfaces on two sides of the blocks for solid support during drilling. I could reach the blocks from all around, which made it easy to hold them securely without additional clamping. The Clamp-It was simple to set up, too. I lined up the bit with the centerpoint of my block, slid the plastic square up against the wood and clamped it to the table. Worked like a charm.
