Who this is for Designed for professional carpenters, hobbyists, and any user who frequently changes drill bits and needs faster, more precise work. Key benefits Extends reach and access: the extension bar lets you drill in tight or hard-to-reach places without repositioning the workpiece. Faster bit changes: the 6.35 mm (1/4") hex shank and quick-change design speed up swaps for continuous workflow. Better angle control: the 20° swivel (pivot) joint provides controlled angular access where a straight bit cannot reach. Secure and reliable: built-in locking mechanism holds bits firmly during use, reducing slippage and improving safety. Durable construction: made for repeated professional use to maintain performance over time. Broad compatibility: works with a wide range of drill and driver models that accept a 6.35 mm hex shank. Main features 20° swivel/pivot joint for angled drilling and improved maneuverability 6.35 mm hex shank for fast, secure bit engagement and compatibility with standard quick-change chucks Locking mechanism to keep bits locked in place under torque Robust design intended for frequent use by professionals and enthusiasts How it solves common problems Eliminates awkward repositioning when access is limited: pivot the head to reach screws or holes at an angle instead of forcing the drill into place. Cuts downtime caused by repeated bit changes: the hex shank and quick-change system let you swap bits in seconds. Reduces stripped screws and downtime from slipping bits: the locking mechanism maintains a tight grip during high-torque operations. Typical applications / use scenarios 1. Cabinet and furniture assembly: reach hinge screws and mounting hardware in tight cabinet corners without removing doors or panels. 2. On-site carpentry and remodels: drill and drive at an angle behind HVAC ducts, inside stud bays, or under countertops where a straight driver won’t fit. 3. Repetitive fastening tasks: production environments or DIY projects where frequent bit swaps and reliable retention speed up the job. Why choose this extension bar Practical angle flexibility, quick-change compatibility, and a locking mechanism make it a simple upgrade to any toolkit for improved speed, precision, and reliability in professional and hobbyist work.
