Pro-Tip: When drilling through heavy rebar, listen to your core motor. If the RPMs drop significantly, slightly reduce the feed pressure to allow the diamonds to grind through the steel without glazing. Always maintain a consistent water flow to flush out metal and concrete slurry, which prevents the bit from binding and overheating.
