Hi there, B&D is a tapgun that means you drill a hole according to the tap
size, (see chart) drill and tap chart, and instead of turning the tap by hand,
you put it in machine, use cutting oil, squeeze trigger, apply light pressure
forward, the tap will turn CC, when pull back machine, tap will turn
CCW...depends of material used, and status of tap, you may move back and forth
until the drilled hole is completed with thread.....it is a great tool...treat
it with great care....I use it in electric panels build
