3. Setup and Compatibility
These accessories are designed for use with most rotary tools. Ensure your rotary tool is compatible with accessories featuring a 1/8-inch (3.175mm) shank diameter.

Attaching Accessories:
- Power Off: Always ensure your rotary tool is unplugged or its battery is removed before changing accessories.
- Loosen Collet Nut: Use the provided wrench or your tool's collet wrench to loosen the collet nut.
- Insert Shank: Insert the shank of the desired accessory into the collet. Ensure the shank is inserted as far as possible to provide maximum grip and minimize run-out.
- Tighten Collet Nut: Hand-tighten the collet nut, then use the wrench to firmly secure the accessory. Do not overtighten.
- Test: Briefly run the rotary tool at a low speed to ensure the accessory is properly seated and balanced before beginning work.
4. Operating Instructions
Always wear appropriate personal protective equipment (PPE), including safety glasses, gloves, and a dust mask, when operating a rotary tool and its accessories.

General Usage Guidelines:
- Speed Control: Match the rotary tool's speed to the accessory and material. Lower speeds are generally better for polishing, delicate work, and softer materials. Higher speeds are suitable for cutting, grinding, and harder materials.
- Light Pressure: Allow the accessory to do the work. Excessive pressure can cause premature wear, damage to the accessory or workpiece, and potential kickback.
- Workpiece Security: Always secure your workpiece firmly to prevent movement during operation.
- Ventilation: Work in a well-ventilated area, especially when generating dust or fumes.
Specific Applications:
- Sanding: Use sanding bands and discs for shaping, smoothing, and removing material. Start with a coarser grit and progress to finer grits for a smoother finish.
- Cutting: Emery and fiberglass cut-off wheels are for cutting metal, plastic, and thin wood. Always cut away from your body and use a cutting guide if possible.
- Drilling: HSS drills and diamond-point drill bits are for creating holes in various materials. Use appropriate speed and cooling for the material.
- Polishing: Felt wheels and points, along with polishing compound, are used to bring a shine to metals, plastics, and other surfaces.
- Grinding: Various grinding stones and wheels are suitable for sharpening, deburring, and shaping hard materials.
5. Maintenance and Storage
Cleaning:
- After each use, clean accessories to remove dust, debris, and residue. A brush or compressed air can be effective.
- For polishing accessories, remove excess compound.
- Inspect accessories for wear or damage. Replace worn or damaged items immediately.
Storage:
Store all accessories in the provided solid storage box to keep them organized, protected from damage, and easily accessible. Keep the box in a dry, cool place away from direct sunlight and moisture.

6. Troubleshooting
Common Issues and Solutions:
- Accessory wobbles or vibrates excessively:
- Ensure the accessory shank is fully inserted into the collet and the collet nut is tightened securely.
- Check if the accessory is bent or damaged; replace if necessary.
- Poor cutting/sanding/grinding performance:
