Are you troubled by the mixing of screws of different lengths?
The unprecedented driver "Skilled Worker" developed by our company. For example, even if an 8mm screw is mixed in with a 6mm screw, it can detect this during the tightening process and prevent it from being released.

basic information
During the screw tightening operation, the built-in motor captures the number of rotation pulses generated and automatically detects any tightening defects. After tightening one screw, the driver recognizes the maximum and minimum pulse counts required to reach the component and sets the acceptable range for judgment. If screws of different sizes are used during the operation or if the bit lifts during tightening, the pulse count will fall outside the range, leading to a determination of a defect. When a defect is detected, an alarm sounds, and a pass/fail judgment on the screw tightening is made. An LED indicating PASS (pass) or Fail (fail) lights up on the main unit's small screen to inform the operator. It is also possible to connect to a network for centralized management. - It operates when connected to a power source. (DC 30V / 20V) Safe and secure design with low voltage output.

Applications/Examples of results
The detection of poor screw tightening is easy, which enhances peace of mind during work. - Confirmation through pulse management is achieved for deep hole operations where the bottom surface is not visible. - Prevents tightening of screws with different lengths. - Detects pinching of wiring cables during assembly. - Detects insufficient torque during screw tightening. - By connecting with external input/output, centralized management via network connection is possible. (External input/output dedicated cables are sold separately.)

Company information
Our company was founded in March 1970, starting the manufacturing and sales of electric screwdrivers and special screws (Totsune screws). The Totsune screw is characterized by a round hole formed at the center of the negative screw head, and it all began with that screw. Since the bit's tip can be guided accurately into the groove of the screw head in one go, the company name was inspired by the concept of a hole-in-one in golf. We always strive to create products based on this hole-in-one system as our motto.
