jonw Posted December 16, 2017 Share Posted December 16, 2017 I am getting a 550C for Christmas from my AWESOME Wife. I picked up a couple of LED bulbs that are .630 .O.D. I am looking for the center hole size on the 550C tool head for my own light. I hope this bulb will fit. Can anyone give me the size of the 550C tool head center hole? Thanks in advance!!

Flatland Shooter Posted December 17, 2017 Share Posted December 17, 2017 (edited) On one of my 550 toolheads the center hole is 0.545" in diameter. The OD of the Inline light I use is 0.540".

jonw Posted December 17, 2017 Author Share Posted December 17, 2017 Thanks for the reply! It sounds like the bulb I picked up will be to large for the center hole. I guess I can angle it off the side and aim it towards the bullet seating die so I can check the powder level. Thanks again!! Link to comment Share on other sites More sharing options...
