Installation Notes

Installation is performed by the same trade professional servicing or operating the hole saw arbor assembly. Power down the drill or driver completely before swapping the pilot bit. Confirm the hex shank is fully seated and locked in the arbor chuck before resuming operation. Inspect the bit for wear or damage before each use, as a dull or bent pilot bit can cause the hole saw to walk off center.
