Lock Defeat Technologies USDDT Universal Safe Drilling Depth Tool

Universal Safe Drilling Depth Tool This new tool allows the safe technician to have absolute drilling depth control when drilling free hand or with a lever rig. It gives you the precise depth control similar to a drill press. It works in conjunction with any length 1/4" or 5/16” diameter drill bit or end mill of your choice.  Here is how it works Once you have penetrated the hardplate and want to be sure you do not drill too deep into your target area, simply stick the magnetized tool on the safe located over your existing hole.  Turn the blue adjustment collar clockwise until it comes to a gentle stop. Insert your drill bit through the tool until it bottoms out in your drilled hole. Slide the precision 1/4" or 5/16” drill stop clamp over the shaft and tighten it up against the tool. Turn the blue adjustment collar one revolution counter-clockwise and begin drilling. The tool will now allow your hole to be drilled .050” deeper. Repeat turning the adjustment collar until you have safely drilled the distance required. The adjustment collar has approximately 3/8” of travel. If your hole needs to go deeper, simply turn the blue adjustment collar clockwise until it comes to a gentle stop and re-position the drill stop clamp on the drill bit and begin drilling again.
