The motor consists of a special brushless motor for the interiors and does not cause as much friction as the previous models. In addition to this, it also consists of replaceable carbon brushes. 

The chuck diameter starts from 1.5 mm to 13 mm. The ability to go up to 13mm allows one to attach several drill bits irrespective of the bit’s diameter. In addition to this, the handle of the drill contains rubber padding. It will act as a firm grip while using the training. 

The drill offers an impact rate of 27,000 beats per minute and 1800 revolutions per minute. The settings for the torque ranges from 1 to 20. The head of the drill is adjustable in that it can go from a “normal” drill to a “hammer” drill.

The battery is nestled conveniently at the bottom of the handle. It contains a button that, upon pressing, releases the battery. The battery connects with the cumbersome charger. The charging time is said to be around 50 minutes.
