Frequently Asked Questions
Q: What drill or driver types are compatible with this hex shank extension bar?
A: These extension bars feature a standard 1/4" (6.3mm) hex shank, making them compatible with the vast majority of cordless drills, power screwdrivers, and impact drivers that accept 1/4" hex bits. Simply insert the bar into your tool's chuck and attach your preferred bit to the magnetic tip.
Q: Can I use these extension rods with impact drivers?
A: Yes. The high-strength steel construction and self-locking quick-release mechanism are designed to handle the torque demands of most standard impact drivers, making them suitable for both light and more demanding fastening tasks.
Q: What is the difference between the 3-piece and 5-piece sets?
A: The 3-piece set includes three extension rods in a selection of available lengths (50mm–300mm), while the 5-piece set includes all five lengths — 50mm, 60mm, 100mm, 150mm, and 300mm — giving you maximum versatility for any job. Choose the 5-piece set if you need a complete range of reach options.
Q: How does the magnetic tip work?
A: A built-in magnet at the bit-holding end of each extension bar keeps your screwdriver bits firmly seated during use, reducing the chance of bits slipping or falling. This is especially helpful when working overhead, in tight spaces, or in hard-to-see areas.
