A diamond core drill bit for glass is a specialized tool designed for drilling holes in glass materials. Diamond core drill bits are known for their durability and efficiency in cutting through hard materials, and the use of diamond ensures a precise and clean hole. To prevent overheating and to lubricate the cutting action, it's often recommended to use water as a coolant during the drilling process.
