I recently acquired a Bridgeport Series I Rigid Ram CNC mill (old Boss 4 but refitted with Centroid M400). I also picked up a good selection of NMTB 30 tool holders. Unfortunately, I can't use some of the holders without a drawbar (shell mill and collet chuck types) so I need a drawbar. I also should mention that I have the Erickson QC spindle (not the quick switch) and the variable speed control. I checked the Kurt website but I am not sure which model drawbar I need. They have two part numbers: BR1010 for almost all T-30, variable, and a BR1017 for a Series I std 2J (T-30, Erickson). I am fairly new to this type of machine and am not familiar will all the different abbreviations Could anybody who has the answer to this please help me out.
Thanks
