Drill/Countersink
The Drill / Countersink serves multiple functions in one. First, the drill portion of the cutting tool cuts the pilot hole for screen insertion. Next, the countersink cuts a chamfered hole with a tapered opening, allowing the screw to sit completely flush with your work piece. When one end of your cutting tool wears out or stops performing optimally, simply flip the countersink over and get back to work. Time is money, and custom cutting tools from Valley Tool Inc. ensure your business saves both!
