Utoolmart Flexible Shaft Extension Drill Bits, Magnetic Extention 1/4" Hex Shaft Screw Drill Connection Tip, 6.7-inch Flexible Drill Bit Extension, for Electric Screwdriver Power Impact Drill

6.7-Inch Flexible Drill Extension Shaft, 1/4″ Hex Carbon-Steel
170 mm Length for Deep, Tight Spots
Slides past obstacles inside PC cases, cabinets and furniture where standard bits can’t reach—no more disassembling half the project just to tighten one screw.

Electro-Plated for Rust-Free Durability
High-carbon spring steel resists kinks and delivers long-term torsion strength; bright plating wipes clean and shrugs off corrosion.

Bends Smoothly, Snaps Back
Precision-wound coils allow full 360° articulation while an internal spine returns the shaft to straight alignment when released—perfect control in cramped quarters.

Dual 1/4″ Hex Sockets with Magnet Catch
Magnetic ends grip both driver and bit—swap bits in one second, no dropped hardware. Works with cordless drills, impact drivers* and hand drivers at ≤300 RPM.

From PC Builds to Auto Trim
Ideal for electricians, furniture installers, hobbyists and mechanics—drive screws behind dashboards, inside junction boxes or under sinks without contortion.

FAQ
Q 1 | Will it work with an impact driver?
Light-duty impacts at low speed are fine. For high-torque impact wrenches, use a rigid extension.
Q 2 | How much can it bend?
Up to 90 ° in any direction; tighter bends may reduce torque transfer.
Q 3 | Is the magnet strong enough for larger bits?
Yes—it firmly holds standard 25 mm driver bits and most 50 mm power bits.
Q 4 | Can I lubricate the coil?
A drop of light machine oil keeps the flex joints silent; wipe off excess to avoid dirt build-up.
