The bimetallic hole opener with M42 bimetallic teeth ensures smooth sawing and is suitable for materials such as building materials, thin iron sheets, and thick cast iron, with a wide range of applications;
The bimetallic Hole Saw drill bit has the strongest resistance to tooth detachment among all metal hole openers, so even if other Metal Hole Saw drill bits are not good at making holes in materials such as round pipes and thick plates, the bimetallic hole opener can still be competent. Currently, it is widely used in the installation of fire pipelines and round pipes;
The product specifications are the most complete, ranging from 13mm to 230mm, including various non-standard specifications and can be customized in small quantities.
Points for Attention:
1. Always wear eye protection glasses when using;
2. Ensure that the drilling material is tight and avoid rotation;
3. Refer to the tachometer and adjust the drilling speed for different sizes and materials;
4. When opening a hole, it should be perpendicular to the surface of the material being cut, and remember to tilt it to prevent the edge from cracking due to high-speed rotation;
5. When drilling thick plates, pipelines, and other materials that require the removal of springs, the springs can be removed, but the drill bit must not be removed. When the handgun drill is running at high speed, the hole opener is not positioned, which is prone to deviation and is very dangerous.
