The Gyro has a 4V MAX lithium-ion rechargeable battery capable of holding a charge for up to 18-months. The charging slot is conveniently placed on the bottom of the handle and out of the way if the user needs to charge the tool and use it at the same time.

The Gyro has the ability to operate at 180 revolutions per minute and apply 35 inches per pound in torque while screwdriving. Depending on how steep the user turns the Gyro after activating the screwdriver, the gyroscopic technology will control the speed of the screw bit. The user needs only to rotate their wrist one-quarter turn to the right for a clockwise motion or left for a counter-clockwise motion. The Gyro also has the ability to fluidly change from clockwise to counter-clockwise, or vice versa. For added functionality, the Gyro also comes equipped with a bright, white, LED light that will illuminate where the user is aiming.


The Gyro, while simplistic and small in design, is versatile and functional in use. Although the Gyro only comes with two standard screwdriving bits, it has the ability to accept many other standard bits, making it a perfect tool for many screwdriving needs. The Gyro’s small design also makes it ideal for use in tight or cramped spaces, where other larger screwdrivers may not fit. Additionally, the small size combined with its long charge time affords the user the ability to store the Gyro almost anywhere.
