Setup
Proper setup of accessories is crucial for safety and performance. This kit includes universal copper collets and a wrench for secure attachment.
1. Selecting the Correct Collet
The kit provides four universal collets (1/16 inch, 3/32 inch, 1/8 inch x2) to fit most rotary tools, including WORKPRO, DREMEL, and MILWAUKEE. Choose the collet that matches the shank size of the accessory you intend to use.

2. Attaching Accessories
- Ensure your rotary tool is unplugged.
- Insert the appropriate collet into the rotary tool's collet nut.
- Insert the accessory shank into the collet, ensuring it is seated as deeply as possible without the accessory touching the collet nut.
- Tighten the collet nut using the included spanner/wrench until the accessory is firmly secured. Do not overtighten.
- For sanding bands, felt wheels, and other wheels that require a mandrel, first attach the wheel to the mandrel, then insert the mandrel into the collet.

Operating Instructions
This kit supports a wide range of applications. Always refer to your rotary tool's manual for specific operating speeds and safety precautions.

Figure 6: Common applications: Cutting, Sanding, Carving, Drilling.

Figure 7: Common applications: Grinding, Cleaning, Polishing.
1. Cutting
Use cut-off wheels (fiberglass, heavy-duty, or regular) for cutting wood, metal, plastic, and other materials. Select the appropriate wheel based on material hardness and thickness. Always cut in a straight line and avoid applying excessive side pressure, which can cause the wheel to break.
2. Sanding
Sanding bands and sandpaper discs are ideal for shaping, smoothing, and removing material from wood, metal, plastic, and stone. Start with a coarser grit for material removal and progress to finer grits for a smoother finish.
3. Polishing
Felt polishing wheels and various brushes are used for polishing and buffing a wide range of materials to a high shine. Apply a small amount of polishing compound to the accessory or workpiece as needed.
4. Grinding & Sharpening
Grinding stones (rubber, aluminum oxide, silicon carbide) are suitable for grinding, deburring, and sharpening various materials, including metal, stone, and ceramic. Select the stone type based on the material's properties.
5. Drilling
HSS drill bits are included for drilling small holes in wood, metal, and plastic. Ensure the drill bit is securely fastened and apply steady, even pressure. Use appropriate speeds for the material to prevent overheating.
6. Carving & Engraving
HSS grinding points and diamond grinding points are used for detailed carving, engraving, and material removal on wood, metal, stone, and glass. These accessories allow for intricate work and fine detailing.
7. Cleaning
Steel, brass, and nylon brushes are effective for cleaning and deburring various surfaces, including plastic and metal. Choose the brush type based on the material and desired aggressiveness of cleaning.

Maintenance
Proper maintenance extends the life of your accessories and ensures consistent performance.
- Cleaning: After each use, clean accessories to remove dust and debris. Brushes can be cleaned with a stiff brush or compressed air. Sanding and grinding accessories may require a dressing stone to refresh their surface.
- Inspection: Regularly inspect accessories for wear, damage, or dullness. Replace worn or damaged accessories immediately.
- Storage: Store all accessories in the provided durable storage box. This keeps them organized, protected from damage, and easily accessible. Ensure the box is closed securely to prevent loss.
- Rust Prevention: For metal accessories, consider applying a light coat of rust preventative oil if storing in humid conditions.
Troubleshooting
If you encounter issues while using the accessories, consider the following:
- Accessory Wobbles or Vibrates: Ensure the accessory is fully inserted into the collet and the collet nut is securely tightened. Check if the accessory itself is bent or damaged; replace if necessary.
- Poor Performance (e.g., not cutting/sanding effectively): The accessory may be worn or dull. Replace it with a new one. Ensure you are using the correct accessory type and grit for the material.
- Accessory Overheating: Reduce the rotary tool's speed or apply less pressure. Ensure the accessory is not dull. Allow the accessory and workpiece to cool.
- Difficulty Changing Accessories: Ensure the rotary tool is unplugged. Use the included wrench to loosen the collet nut. If the collet is stuck, gently tap the collet nut while turning.
