This design concept for a power drill trainer attachment could be quite helpful those turned off by power tools.
People who aren’t familiar with power drills may now have a chance to give it a go, provided they’re not embarrassed to be seen using a training wheel-like device called the SmartGuide. The first common mistake newbies make is not enough pressure thus leaving the drill but to wander all over before hitting its mark. The SmartGuide makes use of two interset rings that collapse in on each other – keeping your drill bit straight and on the narrow.
I suppose the hair-dryer/secuirity-camera like casing just makes it all the more approachable?
