5. Operating Instructions
The Flex Shaft provides a pen-like grip for enhanced control and comfort during detailed work. Always start with a lower speed setting on your rotary tool and gradually increase as needed for the material and application.
- Fingertip Control: The slim handpiece allows for precise control, making it ideal for intricate tasks like fine engraving, delicate polishing, and detailed sanding.
- Access Tight Spaces: The 36-inch flexible cable enables you to reach awkward angles and confined areas that are difficult to access with the main rotary tool.
- Versatile Applications: Use the Flex Shaft for a wide range of applications including carving, engraving, cutting, cleaning, polishing, and sanding on various materials such as wood, metal, glass, and plastic.
