Why using 2-part ejector pins? Usually, standard morse taper holders have a cutting depth capacity of 50 mm. If no extra-long holders are used, you need for drill depths above 50 mm 2-part ejector pins.
Insert piece 1 into the annular cutter shank. Push piece 2 onto part 1. Drill as deep as 50 mm cutting depth. Then remove piece 2 and continue drilling.
