Extension Set — 80 mm, 120 mm, 140 mm What this set does for you Gives you three adjustable extension lengths (80 mm, 120 mm, 140 mm) so you can reach screws at different depths without changing tools. Holds screwdriver bits securely during use with a locking mechanism and magnetic support at each interface, reducing dropped bits and speeding work. Lets you position and turn screws accurately with one hand thanks to a separated outer sleeve and bit shaft that provide a firm grip while allowing smooth rotation. Protects fingers and reduces wobble on long screws with a self-retracting guide sleeve that covers the screw head during insertion. Key features and benefits Versatile lengths: 80 mm, 120 mm, 140 mm adapt to a wide range of drilling and fastening tasks, from shallow jobs to deeper recesses. Secure bit retention: locking mechanism plus magnetic support keeps bits in place for safer, more efficient operation. One-handed precision: outer sleeve design enables a solid hold and smooth rotation for accurate screwhead alignment and reduced strip risk. Safety and stability: self-retracting guide sleeve stabilizes long screws, minimizes wobbling and helps protect your fingers during use. Compatibility and performance Designed for use with standard screwdriver bits and common power or manual drivers, improving reach and control without changing your bit. Improves accuracy and reduces rework by stabilizing long screws and enabling precise positioning in confined or awkward spaces. Simple to swap between extension lengths for fast adaptation to different tasks. Practical applications Furniture assembly: reach recessed screw locations and hold bits steady while assembling cabinets or flat-pack furniture. Cabinetry and trim work: stabilize and guide long screws in tight or awkward angles for accurate fastening without hand strain. Maintenance and repairs: access screws behind panels, in equipment housings, or inside appliances where reach and control matter.
