After Acquiring more and more router bits, I ran into a slight problem. I was having trouble storing them safely and securely. I used to have all of my router bits just all loose in a drawer, but that was not good for the bits and it was difficult finding the one that I needed. That's when I found this router bit holder. These router bit holders can hold 1/4 inch and 1/2 shank router bits. They are designed to fit a 5/8 inch hole that is drilled into plywood or other materials. The holders are a loose fit so only use them upright.
