The XT291 Brushless Combo Kit includes two premium tools, the XPH14Z hammer drill delivering  up to 2,100 RPM and a full 1,250 in.lbs. of max torque, and the XDT13Z impact driver delivering a full 1,500 in.lbs of max torque.  Both tools have been designed with Makita built brushless motors for longer run time, increased power and speed, and longer tool life.
 
Brushless motor is electronically controlled to optimize battery energy use for up to 50% longer run time per charge
Brushless motor eliminates carbon brushes, enabling the brushless motor to run cooler and more efficiently for longer life
The electronically-controlled brushless motor efficiently uses energy to match torque and RPM to the changing demands of the application
