Operating Instructions
- Secure the Workpiece: Firmly secure the bolt or threaded rod in place, such as in a vise, to prevent movement during the deburring process.
- Attach to Drill: Insert the 1/4 inch hex shank of the deburr bit into the chuck of a power drill and tighten securely.
- Set Drill Speed: Set the drill to its lowest gear. Rotate the bit between 0 - 400 RPM. Do not exceed 400 RPM.
- Apply Pressure: Apply consistent, even forward pressure to the deburr bit against the damaged threads.
- Deburr: Rotate the bit slowly until all damaged threads have been removed and a clean thread end is achieved.
- Use Cutting Oil (Optional): For harder materials, applying a small amount of cutting oil can assist in the deburring process and extend tool life.

Maintenance
After each use, clean the deburr bit thoroughly to remove any metal shavings or debris. Store the bit in a dry place to prevent corrosion. Periodically inspect the tungsten carbide cutting blades for signs of wear, dullness, or chipping. Replace the bit if the blades become dull or damaged to ensure optimal performance and safety.

Troubleshooting
Issue: Bit not effectively removing burrs or threads.
Solution: Ensure the drill is operating at the lowest RPM (0-400 RPM). Verify consistent forward pressure is applied. Check if the material being deburred is excessively hard; consider using cutting oil. Inspect the cutting blades for dullness or damage.
Issue: Damage to the deburr bit cutting edge.
Solution: Avoid using the bit above the recommended RPM (over 400 RPM). Do not use with hammer drills or impact drills, as this will destroy the cutting edge and void any potential warranty.
