lefty, that's not true unless it has a gear box added. the plate only takes the weight of the bit away from the drill and gives added support for those who feel they want more control of using a extra large handle. guessing most of them would be folks converting from gas to cordless systems.
but now with this years version of their best drill casting cracking at the side handle location, a plate is needed to keep that from happening. they will only repair it two times under warranty.
