If you've ever had bad experiences with fitting the little metal depth stops on your drill bit and then watching it slide no matter how much you tighten the itty bitty allen screw, then it is time to make the switch to these.

Let you drill to an exact depth when roughing out mortises or pre-drilling screw holes. They fit all standard 1/16" to 1/2" drill bits. Made of high impact plastic, the collet-like stops hold tight with just a simple twist. Their bright color makes them easy to spot in your tool box.
