Parts List: 8 × Connecting Rod 2 × Base or 16 × Connecting Rod 4 × Base Highlight description: Efficient and Fast: The hexagonal connecting rod is equipped with a strong magnet tip and a magnetic bit holder that picks up and holds screws securely, preventing them from falling out, making it easy and efficient to use, and providing reliable fastening and assembly support for all types of work Flexibility and Easy to Use: With a precisely set length of 60mm (2.36 inches), the coupling bar is designed to make it easy to pick up and place the drill bit, and to change the drill bit when needed Strong Adaptability: This series of connecting rods include 1/4 inch, 3/8 inch and 1/2 inch sizes, which are designed according to common standards and can be adapted to all well known brands of electric drills on the market, providing stable and reliable connection support for various drilling operations Premium Texture: The connecting rod is crafted from chrome vanadium steel and the sleeve is constructed from a premium aluminium alloy. Both of them are strong and stable, anti rust, high pressure and wear resistant, with high strength and hardness, not easy to break and damage, which can fully meet the needs of long term use Wide Range of Application: This connecting rod is suitable for nuts, pneumatic screwdrivers, electric screwdrivers, pneumatic drills, hand screwdrivers and other tools, which is the best choice to meet different conversion purposes. Its characteristic is that only the bottom of the hole is magnetic, the hexagonal rod is non magnetic, you need to pay attention to this difference in order to achieve the best results Detailed description: Description: The hexagonal reinforced structure of the connecting rod effectively increases the contact area with other parts. Its unique internal magnetic design makes the connection more tight, ensures that the drill bit is stable and not easy to fall off, and greatly improves the safety and reliability of the operating process Key Feature: The connecting rod usually adopts a convenient card lock design, simply insert the connecting rod into the corresponding interface, the steel ball will automatically snap into the slot under the action of elasticity to achieve fast connection, and when disassembling, you only need to press the unlock button or apply a certain amount of external force, you can easily pull out the rod, which greatly improves the work efficiency Specification: Texture: Chrome Vanadium Steel Size: Shortest Rod: 6cm Longest Rod: 7.5cm Colour: Black + Silver Note: 1. There may be slight differences between the picture and the actual color of the commodity. We will try our best to show you the exact color. 2. Please allow slight dimension difference due to manual measurement.
