Drill Bit Guide for Stable Hole Starts The Alpha® Drill Guide & Water Delivery System gives compatible electroplated diamond drill bits a stable starting position on marble, granite, ceramic, porcelain, and glass tile. The drill bit guide helps prevent the bit from wandering across the surface when starting a hole. Integrated Water Delivery System The system supplies water directly to the cutting edge during drilling. Cooling the diamond drill bit supports cutting performance and service life while combining guidance and water delivery in one accessory. Vacuum-Secured Portable Drill Guide A suction cup creates a vacuum that secures the portable drill guide to the work surface during drilling. After completing a hole, the guide can be released and moved to the next drilling location in seconds. Drilling Guide for Anchor Holes The guide accepts electroplated drill bits from 3/16" through 1-3/8" in diameter. It is particularly useful with 1/4" bits when drilling anchor holes for towel bars, soap dishes, shelves, cabinets, and shower door frames.
