The Alpha® Wet Core Drill Bit is designed for drilling the faucet-mounting holes in counter tops and vanities. It can also be used to make clean rounded corners for square or rectangular sinkholes. The Alpha® Wet Core Drill Bit is very versatile and can be adapted for use in construction trades wherever holes are needed for water, gas and electrical piping, especially when natural stone or ceramic tile is already installed. The Alpha® Wet Core Drill Bit is designed to work on a drill press with a water swivel attachment or free-hand using a wet polishing tool such as the AIR-658, AWP-158 or VSP-110. Since it must be used wet, a tool with a central water-feed or a water swivel is necessary. The convenience of a portable hand polishing tool makes the Alpha® Wet Core Drill Bit very adaptable for a variety of applications.

 

Attach the Alpha® Wet Core Bit onto your center water-feed polisher with a 5/8”-11 spindle. Mark the location of holes that need to be drilled. Use a template as a guide on the stone in order to avoid any mistakes during drilling process. Clamp a piece of stone scrap under the stone being core drilled to prevent excessive chipping or “blowout” on the back side of the stone. Proceed with drilling, pressing steadily until the wet core bit drills through the stone. Refer to the owner’s manual of the tool for proper attachment and usage.
