- Lithium electric drills below 21V are not recommended. When the wall is perforated, when encountering concrete stones, the position of the steel bars must be changed, otherwise it is easy to cause edge collapse.

The Overlord bit is a cutting tool primarily used for drilling metal, so speed control is critical. Recommended drill bit speed: 100-800/MIN, the larger the diameter, the slower the speed requirement. When working with a hand-held electric drill, you need to pay attention to adjusting the speed. If the rotation speed is too fast, the drill bit is easily damaged. Do not knock when using, the workpiece must be fixed, and the drill bit will break when the workpiece swings during operation.
-
For metals with high hardness and many magazines, the rotation speed is slower than ordinary drilling, and the cooling effect is better. For products with a large thickness, if there is abnormal chip removal, the chips should be removed in time. Drill bits can be reground.
