When drilling to a set depth, collar-type drill stops — think donuts — provide a less-than-ideal solution. Since they’re metal, they may damage the drill bit or mar the work surface. What’s more, you need one for just about every drill bit size, and when it’s time to use or adjust them, you have to find the right size Allen wrench. Recently I stumbled across something that may replace the metal, collar-style stop in my toolbox: adjustable plastic drill stops.
Made from brightly colored, high-impact plastic, you can spot these drill stops easily in your toolbox or drawer. They come in sets of two: the smaller one fits bits sized 1/16″ to 1/4″, and the larger fits bits sized 1/4″ to 1/2″. You simply twist the threaded sleeve around the internal double-ended collet to lock it at the desired depth.
At $5 to $6 a pair, are these stops the slickest invention since sliced bread, or worthless pieces of plastic? Tell us what you think in comments.
