Alpha Wet Core Bits

The Alpha® Wet Core Drill Bit is designed for drilling the faucet-mounting holes in countertops 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, concrete 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-680, AWP-158 or VSP-320. 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. Available in 3/8”, 1/2”, 3/4”, 1”, 1-1/4”, 1-3/8”, 1-1/2”, 2 and 2-1/2” sizes, these wet core drill bits are ideal for common faucet hole applications. The 5/8”-11 arbor is a common size found on most drills and polishing tools in the marketplace today. The direct sintered metal segments are brazed to the steel core and provide the long life and aggressiveness expected from a quality core bit. We recommend a template be used when drilling free-hand and a scrap piece of stone be clamped under the stone to prevent excessive chipping on the backside of the stone.
