Widely used for drilling various materials such as steel, wood, thin iron, aluminum alloy, etc.
Note:
1. During operation, it is necessary to inject water to cool the drill. When Uranus is in operation, the high temperature flue gas is prone to annealing, avoiding the life of the drill.
2. Titanium drill bits are very suitable for cutting holes on different materials such as brass, wood, plastic, etc., with a hardness of less than 25 degrees; 1-5 mm iron, aluminium, wood, plastic, carbon steel, durable.
3. When drilling a new hole with a new drill, it is necessary to remove debris (rocks, debris, etc.) around the hole. When rotating, slowly ventilate near the surface to prevent the drill from being knocked down and damaged.
4. When the drilling tool is in the well, the rotation is strictly prohibited to prevent the drill from falling into the well.
