    tapping fluid

    i am planning on tapping (4) 3/4-16 holes 2" deep in 1018 steel. i have some high quality thread form taps that i had made. should i use a tapping fluid on these or just use my normal coolant? the coolant manufacture states that it can be used for tapping but ive only ever done 3/8 max diameter before. never this large.

    I think I would prefer the tapping fluid. I am not sure if the concentration of the coolant will be enough for tapping if used at the regular dilution.
    Regards,
