These extensions solve one of the major problems with forstner bits---their limited depth capacity. WoodRiver forstner bit extensions are designed to be used specifically with WoodRiver forstner bits with a short and a long length sized for the appropriate bit shank diameter. Bits are securely held in place with two socket head set screws to hold the original bit shank.
