This diamond coated core drill bit removes a complete circle from glass, tile, ceramic or other materials and only needs water for lubrication. Excellent for making clean and accurate hole on glass, tile . High quality and long life span. Start your hole diagonally, make a round trace and then hold drill straight. Add water for coolant and drill slowly. Package included: 20 x Diamond Coated Hole Saw Drills
