Details: 

The Makita® XGT® 40 Volts cordless 2-piece combo kit is built with brushless motor which offers optimum performance speed of 0 to 650 RPM and 0 to 2600 RPM (0 to 9750 and 0 to 39000 BPM) as well as torque of up to 1250 in-lb. This variable 2-speed hammer driver-drill has a 4-speed power selection impact driver and a electronic digital clutch for changing tool settings as per your requirement. Self-drilling screws can be easy tightened either in thick or thin gauge metal by using tightening mode or T-mode. The XGT® digital communication safeguards the device from overload, over discharge and overheating thus making this tool perfect for use in heavy-load applications. The XGT® multi-layer contact interface and sturdy rails construction make sure that tools and batteries are continuously delivering optimum power output even on high-current demands. The Extreme Protection Technology (XPT™) safeguards the motor and bearings from dust, debris and water and ensures long lasting usage. If wheel is forced to stop, active feedback-sensing technology (AFT®) turns the motor off. It is suitable for use with Makita® 40 Volts max XGT® lithium-ion batteries. This product comes with a GPH01Z model, GDT02Z model, 40 Volts max XGT® 2.5 Ah battery with a charging time of less than 28 minutes, max XGT® 4.0 Ah battery with a charging time of less than 45 minutes, charger and a tool bag. The tool, battery and charger has limited warranty of 3 years.
