Self Setting Parallels for the Drilling Vice

[Metaler]

When drilling a part, supported by parallels in the drilling machine vice it is probable that, like me, you have had the problem of keeping the drill away from the parallels as the drill breaks through. The device in this video virtually eliminates the problem, except if any part of a holes diameter breaks into an area closer than 2mm from its edge. Even then, there are ways to avoid the problem whilst still using the device.
