This is a 100% 3D Printed Set of 5, Router Bit Holder Inserts. These little guys are great for storing both 1/2″ Shank and 1/4″ Shank Bits. Just drill a 5/8″ Hole into a piece of wood that is at least 3/4″ thick and tap the inserts into place. I do recommend using a 5/8″ Forstner bit to drill the holes as the fit will be the best. You can always add a drop or 2 of glue to the inserts when you tap them in as well. The insert has some glue ridges built into the outside of the insert for this purpose.

These Inserts are completely 3D Printed and will show layer lines in the final product. This is due to the FDM 3D printing process and has no effect on the function of the tool.
