If there are more, the work becomes a torment. Your hands get sore and blisters appear on them in just an hour. So if you need to tighten a lot of screws or bolts, it'll be much better to use an electric screwdriver. It can tighten screws as small as 3 mm in diameter. This makes electric screwdrivers perfect for repairing and assembling various devices such as TV sets and computers. The basic difference between an electric screwdriver and a drill driver is that drill drivers are much more powerful. However, they can not work long-term (more than 40 minutes). Electric screwdrivers can be battery or mains powered. The former are more common and mobile, the latter are more powerful. Batteries that are used in electric screwdrivers have voltages from 3 to 7 V.Power of electric screwdrivers ranges from 150 to 200 or 300 W. This is enough for performing most assembly operations. Torque of electric screwdriver rarely exceeds 6 nm, and the rotation speed is about 150-200 rpm. All electric screwdrivers have the reverse function, and the most "advanced" ones have also the "strike" function.Most electric screwdriver designs do not have sockets; instead, they have bit holders that secure bits for different types of screws. Although there are professional screwdrivers with collets. A set of bits can be quite impressive - up to 150 or 200 items. Handles of most electric screwdrivers belong to the "break in two" type. They can be secured in several positions ranging from 90 to 180 degrees with respect to the body. Electric screwdrivers are usually sold in a special case along with a set of bits. Some models are equipped with a special stand, which functions as a charger. MIS 1 Micro Screwdriver with adjustable torque ranging from 0.35 to 2.0 Nm. It is quiet, light, and has a slip clutch. It is supplied with 16 replaceable bits of chrome-molybdenum. This screwdriver is used in automated machine assembly lines, as well as by modelers and watchmakers. The three stage planetary gearbox offers a reduction ratio of 93:1, yielding the ideal speed of 200 - 250 rpm, depending on the type of network adapter which is supplied individually. The clutch has 5 stages adjustable from 0.35 to 1.0 Nm. Tightening torques can be selected precisely. The sixth stage bypasses the clutch and creates a moment of 2.0 Nm. The switch is located on the body and has three positions: ON - OFF - REVERSE. Fiberglass reinforced nylon lends high impact resistance to housing. The chuck is designed for bit shanks up to 6 mm (1/4 inch) in size. The flexible cord is 200 cm long. The device operates off 12-16V DC. CT-3410 Electric Screwdriver specifications: Supply voltage: 24V. Rotation speed: 1000 rpm. Operating time: 2-10 FCT / cm. Slot diameter: 4mm. ST-3420 Electric Screwdriver has different parameters. The operating torque ranges from 2 to 12kgf/cm, and the slot is 5 mm in diameter. SK-2205LSB, SKD-5300B and SKD-2000B electric screwdrivers are used for conveyor assembling units and blocks of electronic equipment. They have a low torque that can be adjusted with an accuracy of + / - 3%. The screwdriver uses high-quality engine with a cooling fan for continuous operation. It is light and small in size, so it can work with tiny screws (up to 1 mm in diameter). Removable bits allow you to work with all types of screws. When the set torque is reached, the screwdriver stops automatically. These models differ in specifications. Specifications: • supply voltage: AC 220V....240V/50 Hz • torque (kg / cm): 0.5 ... 7 (+ / -5%) • rotation speed (rpm): 1000 • screw diameter (mm): 1.6 ... 2.6 • length (mm) / weight (g): 230/480 • BIT SS type: 6.5 mm We also provide power supplies for electric screwdrivers. For example, SKD-2 power supply is designed for SKD series. Specifications: • Input Voltage - AC 220V (50/60Hz) • Output Voltage - DC 32/24V • Current - 1A The power supply for CT-3410/CT-3420 is called ST3200. Its input voltage is 220V. The output voltage is 30V. The load current is 600mA. You can buy an automatic screw feeder in addition to your electric screwdriver. It feeds screws of 2 to 3 mm in diameter one by one. The device has an electronic screw calculator. The feeder will significantly improve the productivity of assembly operations. Using electric screwdrivers will help you work more efficiently and avoid blisters and fatigue. [endtext]
