How to Change The Bit for Electric Screwdriver #1.The selection of the electric screw driver bit Selecting the bit specification model of electric screw driver is mainly based on: torque, joint station, screw groove size, screw station length and diameter reduction requirements; At present, the electronic industry is rapidly changing, more and more special screws or other fasteners appear on the assembly market. For these screws, non-standard customized bits can meet the locking requirements. Therefore, customers need to provide the bit drawing or use the caliper to measure the size of each part of the bit. If not, customers can directly sent the screw sample to the bit manufacturer to match. The engineer will help confirm the specifications of the electric screw driver and select the appropriate bit to ensure production efficiency. Bit selection step 1.Determine the size and shape of the electric screwdriver bit jack According to the size and shape of the shank diameter, there are 4 main types of bits:  5MM Hexagonal shank: the height of opposite side is 5MM  6.35MM Hexagonal shank: the height of opposite side is 6.35MM  4MM Round shank: Shank diameteris 4MM  5MM Round shank: Shank diameteris 5MM 2.Determine the screw size.

Since it has been rubbed with the screw, it needs to be replaced after a period of use. There are five steps, the steps are as follows:  Prepare one electric screwdriver and one φ4 bit. φ4 means the handle of the batch head is a 4mm outer round handle  Press down the shaft cap of the electric screwdriver with the female finger, so that the steel ball of the card starter bounces back and the shaft core leaks out.  Put the screwdriver head down on the card position and release the shaft cap.  Pull the puller to judge whether it is installed in place  Make sure to install the OK and then power on the electric screwdriver to lock the screw #3. Conclusion The bit is one of the important parts of the electric screwdriver. Only by selecting the matching bit and changing it in time can the electric screwdriver work efficiently.
