There seems to be two standards for the smaller size. One is 19.00 mm and the other is 19.05 mm. If the hole of the tool holder is 19.05, will it be ok to use tools with 19.00 shank ? Common sense says no but the vendor said its ok . Advice needed.
This make all the difference, the cutters stay sharp so much longer!I have an arbor for my annular cutters that feeds coolant.
