specifications Product Name: Brazed Sawtooth Tile Drill Hole Opener Product Material: Aluminum Alloy Description: Wet dry dual-use: In dry drilling mode, there is no need to add additional water, making the operation more convenient; The wet drilling mode can effectively reduce dust and heat, extend the life of the drill bit, and ensure a safer and more reliable drilling process. High quality materials: Using high-quality materials, alloy serrations are firmly welded onto the drill bit to form sharp cutting edges. Whether it is all ceramic tiles, marble, granite or vitrified tiles, they can be easily penetrated to achieve fast and precise drilling operations, meeting various construction and decoration needs. Efficient cutting: The unique serrated design greatly improves the cutting efficiency of the drill bit, enabling the drilling of large diameter holes in a short period of time, saving a lot of time and energy compared to traditional drill bits. Long service life: able to withstand high-intensity workloads. The precision machining process ensures the concentricity and balance of the drill bit, which can maintain stable operation even at high speeds, avoiding the occurrence of vibration and offset phenomena, greatly extending the service life of the product Strong applicability: This drill bit supports both dry and wet drilling modes, making it easy to handle whether it requires fast construction or pursuit of fine results.
