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.

Street Pricing starts at around $15 and are available through the Eagle America website.

    Just premeasure your bit and put a piece of tape where you need to stop drilling.

    Um…tape works pretty good. And it’s adjustable too!

    Yep, I’m all for the tape method as well – except if you’re drilling a series of holes into, say, masonry, the masking tape does get a little chewed up, but most of my larger drill bits have old pieces of tape on them from some time in the past…

  4. Myself says:

    The tape gets chewed up, and occasionally I swear it just plain moves up the bit. The big problem, though, is trying to judge the position of a tape band, (or other drillbit marking) when you’re essentially behind it. Having an assistant positioned off to the side is nice, but not always practical.

    I should make up a little mirror wedge that I could set on the floor next to the hole, so I could see an edge-on view of the bit from my vantage point behind the drill. I’m sure it would get coated in concrete dust, but a new filter in the vacuum should minimize that.

  5. Me says:

    Another (sort-of) good reason to use the tape method:
    If you apply your tape so it looks like a flag, when it gets close to the surface you are drilling it will brush the saw dust out of the way.

    Drill stops aren’t that expensive and their infinitely adjustable. For less than $15 you can get a set of 4 or 5. Al little more classy than the tape method.

    I’ve never had good luck with the little drill stop collars, they always seem to work their way up the bit. I guess since they’re somewhat fastened on there, I might be pressing down to the stop but not so much that they should move. I’ve decided that the tape method works best for me. Cheap, easy and it works.

    If these don’t cost any more than regular bits, then the idea is really great. I like this type of innovation in areas where there doesn’t seem to be room for any more.
