Optimizing engineering, using the same battery source of power, Phasor brings the ability to drill 14-mm burr holes in under 40 seconds.  Inquire with us about our 1.5x Torque drills available in mid-October, and our higher (up to 12x Torque drill) expected end-November.  Quick-Connect capabilities allow so many driving options with higher torque.  These are in high demand already, so we're accepting advance inquiries if you'd like to get one... please let us know.
