Acrylic jigs are often available for use with Self-Centering Bits, or a jig can be made in a minute by drilling a hole for the Self-Centering Bit in an L-shaped piece of scrap so the bit can be located at a consistent depth.
The Shelf Pin Guides operate on the same principle, but instead of the tapered drill bit of the Hinge Bits, the internal drill bit is a brad-tip drill. The brad tip is made of HSS for a precise, clean hole. Designed for use with shelf pin jigs.
Made in the USA.
