It can be used for drilling hard and brittle materials such as marble, ceramics, cement, and ceramic tiles. The drilling is neat, smooth, and free of broken edges, without causing vibration. The cutting resistance is small, which improves the opening speed. After slotting, it is easy to decorate and debris removal is easy. Attention: Water must be added during the drilling process, and good cooling can prolong the service life of the drill bit Do not dry the drill without adding water, otherwise it may cause damage to the drill bit Suitable for drilling operations in marble, stone processing, granite quartz stone, ceramic tiles, etc Operating instructions: 1. The hole opener is suitable for angle grinders, and can be directly used on hand drills and table drills with a connecting rod. As the hole opener does not have a center positioning drill bit, it must first slowly tilt at a 45 degree angle to contact the marble. After opening the crescent groove, use this crescent groove for positioning, and then drill vertically at a speed of about 800-1000 revolutions per minute 2. During the drilling process, coolant or water needs to be added to extend the service life. At the beginning of drilling, it is necessary to slowly contact objects and not collide with them. The working speed should be low (the larger the drilling tool, the lower the speed). When drilling through, pay attention to slowing down the speed 3. When the chip removal is not ideal, please stop working and clean it before starting work Package Including:1pcs Diamond Hole Saw Drill Bit / 1pcs connecting rod(Randomly send colors) Payment: We accept Paypal only, It is fast, Easy and Safe.
