Thread cutting aid

Its hard to get the tap inside an drill hole in an perfect 90° angle. I work with metal and ive made this to get the tap straight into the drill hole.It really helped my coworkers and me to cut threads in an good angle and without needing to adjust the tap a 100 times :D.Boost MeIf you like this gadget feel free to give it a boost. Its free and i would really appreciate it. Thank you :D
