💡 What is the proper maintenance routine for extending the service life of abrasive core bits
Running fresh coolant through the barrel drastically reduces thermal stress on the cutting edges
- Flush the hollow barrel with pressurized air after every shift to clear packed dust
- Coat the exposed steel flange with light machine oil to block moisture absorption
- Test the chuck grip regularly since loose spindles cause dangerous wobble and kickback
