Now here’s a good idea — integrate a ball bearing into a drill bit stop. When the stop hits the work piece, the bearing will stop and allow the bit to keep spinning: no marring, scratching, or burning from the spinning stop. It’s not a new idea: the Forstner Depth Stop we covered previously uses this, and now so does FastCap with its new Layout Drill Bit for drilling shelf pins for European-style adjustable shelving.

To adjust the depth of the stop, you loosen a set screw with an Allen wrench. Sounds just like a collar stop, doesn’t it? In my opinion, they really missed the boat on this one; rather than selling such a limited-use bit, they should integrate this technology into a set of collar stops.

The Layout Drill Bit will only be available in 5mm and 1/4″ sizes.

    Collar stops… like this? http://woodworker.com/18-id-slipstop-collar-mssu-908-295.asp

    They’ve been around for awhile.

  2. Thanks for the info BC,

    I had a hard time believing that somebody hadn’t thought of them, but for all I tried I couldn’t find any.

    If they are supposed to prevent marring and scorching.. What’s the tape with the crosshairs for?
