Core Bit Conversion Adaptor 5/8 Inch (Male) to 1-1/4 Inch (Female) works great for using smaller diameter core bits threaded at 5/8"-11 on a core drill machine threaded at 1-1/4"-7. This adapter is usually required when using under 2" in diameter wet core bits or dry core bits that have the 5/8"-11 female thread using a Core Drill.
