Features When renovating your kitchen or bathroom walls or fastening mirrors in bathroom or installing shower, you will need to drill holes on mirrors or tiles without cracking them, hence you will need to use these diamond drill bits to make those holes very precise. Our porcelain diamond core drill bit uses vacuum brazed technology, so the bit can be used at a higher temperature cutting harder materials, great for drilling clean holes to granite, ceramic, glass stone brick and marble tile stone Jars and similar materials (not for wood). Dry diamond drill bit integrates wax lubricant inside of the bit. During drilling, this integrated lubricant will melt to cool the cutting surface, perfect for project which lubricant is not applicable. If additional cooling is required, water can be used to prolong the life of the bit and to remove the debris during the drilling process. Steps to drill clean and precise holes 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. 2. Slowly move the drill bit into a more up-right position and wobble the drill bit in the circular motion. 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. 4. Take care when using them as a bit can glaze and burn out if use too fast.
