I have used the X2 to tap 10-32 in aluminum. I give the spindle a couple of turns by hand to start the tap then carefully advance the speed control. To back the tap out I put the gear shift in between positions and turn the spindle by hand. Not really any faster than doing it by hand but it keeps the tap straight. On smaller taps I turn the spindle by hand both tapping the hole and backing the tap out. |
