Accurate Positioning: These bits are designed to position screws accurately without wobble or misdirection, enabling faster and more efficient work. Depth Limiter: The magnetic collar prevents screws from penetrating too deeply, protecting walls and boards from damage caused by overtwisting. Magnetic and Nonslip: Equipped with a magnetic ring that enhances magnetism to securely hold screws in place, making work easier and reducing slipping. Strong and Lasting: Made of chromium vanadium steel, these bits are wearresistant, durable, and resistant to hardness. They are suitable for gypsum board, woodworking board, and drywall. Use scenarios Installing shelves, cabinets, or fixtures where precise screw placement is essential to ensure level, secure mounting and a clean finish. Drywall or gypsum board installation to prevent overpenetration and protect wall surfaces from screw damage. General woodworking and furniture assembly where a secure grip on screws reduces slipping and speeds up workflow.
