4. Pilot Drill Bit: The kit typically includes a pilot drill bit that helps center the hole saw for more accurate cuts, improving precision and reducing the chance of wandering.

5. Quick Change Mandrel: The set comes with a mandrel, making it easy to switch hole saws as needed for different sizes or materials. This feature enhances the kit’s convenience and efficiency.
