What do I need to make the 3 1\2 inch cobra bit fit my Bosch drill?
by Anthony Mauldin 9/17/2018 9:27:48 pm
It is dependent on the connection of the drill. These bits are a 5/8"-11 female thread. If the your drill is a 1/2" connection we offer chuck adapters that will adapt the drill to fit these bits. https://www.contractorsdirect.com/Jacobs-Chuck-Adaptor-5-8-11
