Compatibility: Fits most standard electric drills with chucks, suitable for a variety of setups. Polishing capability: Can polish workpieces with or without threads for smooth finishes. Main function: Quickly damaged bolts and securely tighten nuts in place. Simple operation: Streamlines tasks and avoids replacing expensive or hardtofind hardware. Use scenarios After drilling metal components, use the tool to deburr and chamfer edges to ensure easy bolt insertion and proper fit. In maintenance or work, salvage a damaged bolt by smoothing threads and edges to restore engagement and allow nut tightening without replacing hardware. During preassembly, polish threaded and nonthreaded surfaces to improve fit and reduce crossthreading or binding. Key attributes Function: Deburring, chamfering, polishing, and tightening assistance for bolts and nuts. Compatibility: Designed for use with most standard drill chucks. Size: Built for standard drill compatibility; exact dimensions depend on the model. Material: Specific material not stated; intended for deburring and polishing tasks on metal components. Performance: Enables quick repairs and smoother assembly by reducing burrs and restoring fit.
