So you know when you need to make a hole bigger but don't want to start completely over? That's exactly what this Starrett KA19-N Oops Arbor is for - it's basically your second chance for hole sizing. This clever tool replaces the pilot drill in any Starrett A1, A2 or A10 type arbors, letting you attach a saw that matches the size of your existing hole. That smaller saw then acts as the pilot for a larger diameter saw that you mount on the arbor normally. It's one of those tools you might not need every day, but when you do need it, you'll be so glad you have it. The quality is exactly what you'd expect from Starrett - precision-made and built to last. Whether you're working with metal, wood, or other materials, this arbor helps you correct sizing mistakes or adjust holes without having to reposition your workpiece. It's perfect for maintenance shops, fabrication work, or any situation where hole sizes need adjustment after the initial cut. The simple design means there's not much to go wrong, and it stores easily in your tool chest until needed. If you do any kind of hole saw work regularly, this oops arbor could save you from some serious headaches and wasted materials down the road. Sometimes the best tools are the ones that fix problems rather than create new ones!
