Alright guys, hope you can help me. I purchased a new / old stock Kreg DB50 still in the box. In the beginning I was searching for a DB55 pneumatic version because of the wonderful reviews it got. The main difference between the DB50 and the DB55 is the inline automatic oiler for the drill in the DB55. Anyone who owns a Kreg DB55 can you tell me the make and model number of the oiler in your unit? At one time Kreg made a upgrade kit for the DB50 but have since discontinued the kit. Thanks for all your help!
