Review on 💯 Maximize Precision with Senrob Centering Drill Alignment for Woodworking Projects by Ryan Brunson

I built a first aid kit recently and used euro hinges. A video on You Tube showed a man using self centering bits so I looked them up on Revain and made a purchase. They work great. The outer case fits into the recess surrounding the screw hole in the hinge and you drill a perfectly centered hole every time.
