💡 Expert Pro Tip for Core Drilling:
Safety & Speed: Always match your RPM to the bit diameter. Larger bits (6"+) require slower speeds and higher water volume to prevent segment glazing. If drilling through heavy rebar, ease your pressure and let the Supreme Aligned Diamonds do the work—forcing the bit only increases heat and shortens the tool's life.
