5. Operating Instructions
The WORKPRO Rotary Tool Accessories Kit provides tools for a variety of applications. Always test on a scrap piece of material first to determine the optimal speed and pressure for your task.
5.1 Sanding
Use sanding bands and papers for smoothing rough surfaces, shaping, or removing material from wood, plastic, or stone. Attach the sanding band to its mandrel and secure it in the rotary tool. Apply light, even pressure and move the tool consistently across the workpiece to avoid gouging.
5.2 Cutting
Cut-off wheels (fiberglass, heavy-duty, and diamond) are used for slicing, slotting, and trimming various materials like metal, plastic, or thin wood. Ensure the workpiece is securely clamped. Use a light touch and let the accessory do the work. The diamond cutting wheel is suitable for harder materials.
5.3 Grinding and Sharpening
Grinding wheels, alumina grinding stones, and silicon carbide grinding stones are ideal for sharpening, deburring, and general grinding on metal, stone, or ceramic. Maintain a consistent angle and pressure for best results.
5.4 Carving and Engraving
HSS grinding points and diamond grinding drills are used for detailed work, carving, and engraving on materials such as wood, metal, stone, or glass. Use a slow to medium speed and a steady hand for intricate designs.
5.5 Polishing and Cleaning
Felt wheels, felt wheel points, rubber polishing bits, and polishing compound are used to bring a shine to various surfaces. Brass, steel, and nylon brushes are effective for cleaning and light deburring on different materials. Apply polishing compound to the felt wheel before use. For brushes, select the appropriate brush type for the material to avoid damage.
5.6 Drilling
HSS drill bits (1/8”, 3/32”, 1/16”) are included for drilling small holes in wood, metal, or plastic. Ensure the drill bit is securely fastened and apply steady, downward pressure. Clear debris frequently to prevent overheating.
