Ever damaged a project or wasted time by drilling too shallow or too deep? We have. It can be somewhat of a challenge to gauge how far you are in while drilling, especially if you’re not using a drill press. On these special bits the colored bands make it possible to judge the depth of a hole.
Each of the sequential bands are spaced out every half inch or 10mm (for Metric) for fast gauging on the depth of your progress. While not a micrometer or laser powered depth finder, the bands look to be a good alternative to masking tape or marking your drill bit with a Sharpie or Eraser board marker.
While realistically the best you could accurately gauge with a quick look is about a quarter inch, that quarter inch or 5 mm could be quite helpful if the project requires a hole over an inch deep or so. It’s better than drilling though the table top anyway.
