This gives you the flexibility to use different sizes of bits and attachments on different jobs to suit specific needs. Simple and easy to use: the SDS Max to SDS Plus adapter is very simple to install and remove. Simply plug the SDS Max end of the adapter into the SDS Max tool and then insert the SDS Plus plug on the other end into the SDS Plus drill chuck to complete the connection.
