Using Steps: Step 1: Start Drilling the hole in an angle about 45 degrees to the surface, so the drill has the chance to start and will prevent the drill slipping Step 2: Slowly move the drill bit into a more up-right position and wobble the drill bit in the circular motion Step 3: Do not need to apply much pressure, let the drill bit do the work, you will feel the drill bit break through the back of the glass or tile once the hole is completed Step 4: Take care when using them as a bit can glaze and burn out if use too fast ProductSiteLaunchDate : 2022-04-09T17:16:27.664Z Size : 3/16 in StreetDate : 2015-03-04T00:00:01Z Style : Hex Shank SupplierDeclaredDgHzRegulation : not_applicable SurfaceRecommendation : Ceramic, Porcelain, Tile, Concrete, Marble SurfaceRecommendation1 : Tile SurfaceRecommendation2 : Porcelain SurfaceRecommendation3 : Porcelain SurfaceRecommendation4 : Glass SurfaceRecommendation5 : Plastic SurfaceRecommendation6 : Brick UnitCount : 10 UnspscCode : 27112845
