Installation and Maintenance Guide
Setting It Up
- Ensure your rotary tool collet matches the 1/8 inch shank diameter before insertion.
- Clean the shank with a cloth to remove any dirt or grease for a secure fit.
- Insert the carbide burr straight into the collet, avoiding any angle to prevent wobble.
- Tighten the collet securely but avoid overtightening to prevent damage.
- Test run at low speed first to ensure stability before full use.
Keeping It Going
- Regularly clean the burr with a wire brush to remove metal shavings and debris.
- Avoid excessive pressure—let the burr do the cutting to extend tool life.
- Store in a dry case to prevent corrosion and damage.
- Inspect for wear or dull edges and replace if surface finishes suffer.
- Use proper personal protective equipment like gloves and safety glasses during operation.
